Cool. Checking these out. Any recommendations on eye protection as well? Always struggle with pinching of the safety glasses over the ears with traditional muffs, so these may help.
I realize this video is old but this shows the difference time can point out. "It's just plastic..." We are just learning the dangers of ingesting microplastics into our digestive systems. Cutting a plastic finish is going to introduce small amounts of plastic into your body. I don't know what the safest finish may be, but it isn't something that cures into plastic that is then cut up, thereby getting into your foods.
There is a growing body of research showing that there are micro plastics in food and water we consume daily. Odds are anything you dislodge on a cutting board is going to be large enough to harmlessly pass through your digestive system. It’s the microplastics small enough to get into your bloodstream that are worrisome and those are undetected in the food and water you drink daily. At this point I’m not going to worry too much about it since when I was a kid we had DDT, Asbestos pipe insulation , we played with mercury and had lead based paints.
@@randsipe224there’s research showing that cutting boards do release microplastics. Not only when you cut but also when you dish wash and it releases into water and gets attached to other utensils. I’d avoid any plastic where there’s friction, damage, or liquid contact. Even if it doesn’t cause you any harm (which you might not even know how it affects you, because even scientists don’t know everything), you (and all of us) release more and more of the plastic just by using it into the water, the air, the soil (then crops) for future generations to consume. And can you guarantee they’ll be fine?

Great video, as usual, although I'd like to point out that while lac resin is secreted by bugs it is not actually poop. Long story short, lac bugs suck sap from trees, and most of that sap is converted by the bug into lac, which is secreted by various glands on the insect's body so that it can harden into a protective shell all around the bug. "Droppings" are just that - a waste product that most creatures drop and leave behind because it serves no purpose. So, lac is more like hair than poop - a substance produced by a creature as a secondary protection from the elements. But lac tastes better on jelly beans :)
As a food scientist I can tell you about nut oils. These oils, and in general most oils, are purified or processed to a point where any proteins (the stuff that you would actually have an allergic reaction to if you have nut allergies for instance) would either be virtually nonexistent or denatured to a point your immune system wouldn't interact with it, thus no allergic reaction. This is highly refined oils, not cold pressed essential oils. Essential oils would likely give you a reaction because they aren't processed to remove anything nor are they heated.
Please by all meams go do a study with a group of deathly alleegic children and have them drink a cup of highly refined peanut oil to prove that point. As someone with food allergies I can absolutely guarentee you, it doesnt matter how highly refined it is, we still react. The FDA not requiring highly refined soy oil to be listed as a food allergen is nothing but a lobbied decision payed for by the soy industry.
@@HenryLeslieGraham I don't know about Tung oil much, but it wouldnt be an allergic reaction. Cyanide will kill you also but it's not due to an allergy to cyanide.

Please stay seated in the middle of the proverbial wagon so you don’t fall off , your times not up yet.
My mind did go down the path of accumulated ingestion of microplastics, and I gather that is becoming increasingly problematic (I need to do more research), but I suspect us woodworkers are not going to be major contributors to this even if we do paint some finishes on our products.
2:29 - "and you turned fine, right?" - l'm not sure about that, because of relatively long exposure, or when we are talking about long time effects, which cannot be tracked into single source, but it is made of many sources. And what side effects are yet to be discovered in the future.
I worry about the damage to the finish that will result with a well used cutting board. I have many wood and plastic boards and after a lot of use there is clear damage to the surface. So while contact with a hardened finish may be safe, after enough use that finish is going to start to come off in small pieces and get into food, and while likely small in quantity I think this is the real issue. Not so much a problem with serving ware that will not need to withstand abrasions. Washing and contact is one thing, but repeated cutting is different.
You will also be eating the wood flakes. Although microscopic pieces may not do any long term effects. I’ve had good results with mineral oil and have even used vegetable oil on cutting boards. Even washing them in soapy water, just rinse dry and when I think it needs another coat it’s easy to apply. A teaspoon of oil coats a lot of surface area. The newest reports say that millions of plastic nano particles are in a bottle of water and people are worried about a little flake of polymer.

Thanks for the reminder, I remain amazed and how passionately some folks will defend products carrying the food safe label will defend said products as the only option for anything that might come in contact with food or children. Also thanks for the safety reminder at the end. Cheers from BC!
Even though finishes are contact-safe, there is something to consider when it comes to heat resistance & how well the finish holds up (some just don't). I wouldn't mind a video on which types of finishes hold up best with a hot plate on them, or when filled with boiling water as a wooden cup might be.
Avoid shellac. I made a trivet and tried that as the finish. It looked beautiful but the hot pots that got put on it eventually melted part of it. I sanded it all off and replaced it with my regular beeswax/mineral oil treatment for cutting boards and that's held up fine.
I second this request. My Dad used to make cutting boards as a hobby and used a finish that I don't recall off hand. I forgot the board was in the oven and turned it on to preheat. I realized pretty quickly when I started smelling the tell-tale smell of finish fumes. I pulled it out and allowed it to cool completely and then called my dad for his opinion on what to do. I left that cutting board alone for months before I used it again.
@@halsonger1317 Yea, I've been looking for a film finish that can hold up to things like that but they never seem to last very well. Oils are fine but it'd be nice to find something that can seal the wood pores, but with better moisture resistance than wax.
G’Day fellas , I made a hot pot board from many off cuts of ‘Mackay Cedar’ glued together with ‘Aquadhere’ and finished with ‘Cabots’ Polyurethane and it withstands large dishes of bubbling hot yummy food time and time again. It would be at least 4years old now and still good as. 👍
I have used Walnut oil - salad type from the grocery - on my rolling pins and cutting boards. It takes up to a month to "dry". I was told that the drying is actually a polymerization and oxidation process. It seems to resist moisture but I don't soak these things in water. Does darken the wood a bit to a pleasant brown color. It doesn't become sticky like the board that I used olive oil on (ti was a food preparation board that was not intended to be a treated board). I once used a raw linseed oil - not boiled - on a piece of wood; it takes a month to two months to harden but does soak about an eighth inch into the wood in the process ( I cut the board in half after drying).
Lots of options out there. Personally I use my own mix, a 'bees wax and walnut oil' finish for cutting boards, bowls, wood trays, spoons, utensils etc.
I'd love to hear more about what happens when the finish starts to wear down on a cutting board: does it ever end up in the salad I'm cutting, or does it always go down the drain?
I’ve been debating switching from the standard Mineral oil/beeswax finish for cutting boards for a while, but the ease and speed of application and maintenance without fumes keeps winning my requirements.
THANK YOU! I've been telling people this for years! On my cutting boards, I dilute wood bowl finish with 50% mineral spirits and let the wood soak it up with a few coats. Just enough to seal the wood without a build up of film. It works so much better than mineral oil and wax....
Useful information, well delivered. Thank you. One point on finishes like polyurethane which form a skin. Knives will cut through the skin and so you can expect slivers to come off, and some will end up in your food - yummy! Once moisture gets under the skin, it's only a matter of time before the whole sheet peels away. That's why I prefer things like waxes and mineral oil. Yes they might need reapplication, but that is pretty quick and painless.
I'm thinking of printing the link to this video and place it on my cutting board tags, along with instructions to never put one in the dishwasher or into water for more than a few seconds when washing. Thank you for this video and here is a hearty AMEN!!!
Interesting. All told, though, I’ll stick with mineral oil for salad bowls and cutting boards. After 20 or 30 coats, I have found the wooden surface is essentially impervious to liquids. After use, wipe it out or off, apply another coat of mineral oil. Works very well on cheap teak bowls! Turns them into great presents.
Calm, sensible advice as always. One thing to bear in mind is temperature - hots food on cutting / serving boards could leach stuff out of the finish, so I agree, always check thoroughly. Those interested in BPA might be interested to note some epoxy resins contain it or it’s replacements BPF and BPS, but that’s a different story.
My go to food safe finish is a mixture of mineral oil and bees wax. I turn a lot of bowls and this finish really make the colors and grain pop. For reference, Bob Flexner wrote a book years ago and he states like you did that once cured, all finishes are food safe. Good video 👍👍👍
Love your videos. The information you’ve shared here is good. You are correct that the term food grade is misleading for things that can be toxic. What it actually means is that the product has been produced and handled in such a way that it will not transfer any contaminants that can get into the food. In the case of finishes it could be things such as metal shavings or even bird droppings. However it doesn’t mean that it’s safe to eat as you’ve said.
I often use a mix of beeswax and olive oil (20-25% beeswax to 80-75% olive oil), heated up to combine and apply when hot, so soaks in better. Very easy to apply, both products are edible "raw", and easy to re-treat later
My friend just got an oak table from his grandma. He used a card scraper to take off about a quarter inch of what looked like wax. She told him that she would spray Pledge on it every week for years. Yummy. Thanks for the great vids.
So very helpful!!! Thank you! I forget the brand of “food safe” wood block finish I originally used but I liked it. Currently I go back and forth between mineral oil and watco butcher block oil and finish. The issues I have……….. not fond of the shiny finish, but on pieces that have high contact (spoon edges)… those contact areas get a dried out and worn look that the oil can’t seem to overcome. Just thought I’d share. Any feedback is highly welcome and appreciated!
Hi, Any suggestion for a finish to put on plywood in a high humidity area? I am building a egg incubator so it has to be easy to clean and not off gas after it cures. Thanks.
I saw your comment below about mineral oil and I have to say that is the reason why I use and encourage new woodworkers to start with it: it is the easiest finish for a non woodworker to maintain, and you item can be used immediately. Also there is not any kind of smell or taste to the mineral oil (although that may just be me).
Yes, and mineral oil is one of the few things that won't turn rancid. That may not be an issue directly on the finish, as it may wear away before becoming rancid, but it will in storage. There was a time when you could buy 2 inch thick oak butcher block slabs from ikea for incredibly reasonable prices (15 years ago). So we replaced a sad old counter in our tiny old house with it. Once or twice a year I flooded the thing with mineral oil, letting it sit over night and wipe off. Treated it pretty much like it was impervious to damage (since it was so thick I could remove any actual damage). And it still looked basically new 8 years later. I loved it because I never needed a cutting board! I don't miss that house, but I do miss that counter.
This is a tough topic. I think you gave great advice with broad strokes. I am a Chef and one thing that is never brought up in these types of discussions are food contact surfaces. In the health code there are two types of surfaces. Direct contact and indirect contact. It’s the difference between intentional and incidental contact. Think of it this way if you are preparing food directly on it, that’s a direct contact surface. Such as bowls, cutting boards, pots and pans. Indirect contact are things that food is not prepared on, but has the potential to come into contact with food. Things such as counter tops or your stove top. Cleaning and sanitizing protocol is different for direct versus indirect surfaces. Our woodworking finishes should be thought of in the same way. Personally I wouldn’t use a hard film finish on a salad bowl. Over time it could get brittle and chip off and go into your food. That could become a physical hazard (choking or cut your mouth).
Very informative, you objectively provided concise and accurate data without shamelessly endorsing any one product.... oh, but wait! what's that hideous red thing on the bench? I kept waiting for a cunning smashy-smashy cut where a large leaf-shaped mass would crush that Red Wings cup-holder. My initial reaction was to question your credibility with that "not a nut comment", but the fact that you left it on the bench, where it belongs, shows that you are indeed a master of the wit, and a probably a Leafs fan at heart. Classic!
I still don’t know what to choose for finishing my cup… Same way I solve many problems: I’ll just use what I have on hand. It may take awhile to dry, but you got me started knowing this finish will do.
You make nice educational videos! Compliments :) As long as contact times and temperatures are small and low (as is the case with almost all household apllications of finished woods), your reasoning holds well. Just don't use a finished wood product for food storage (contact times < 1hr), and make sure the contact takes place at regular ambient temperatures or below, and the migration of any harmful ingredients, if present, will be negligably low. It also depends on the kind of foodstuff the wood comes into contact with: watery, fatty, alcohol,... they all have different migration characteristics for different ingredients. A bigger concern would be the wood itself. As a soft and "porous" material, it can easily be damaged beyond the finish (by cutting with a sharp knife...), and harbour moisture - and therewith bacteria - without the means to clean properly. That has nothing to do with the migration of chemical elements from the wood or finish to the food (which is the "food safe" criterion), but is the higher risk in the cutting board application. That is also the reason why we as European machine builders for the food industry are not allowed to use wood as the material to make any machine parts of (EU law differs in that respect from FDA CFR 21)
It's almost creepy how this channel constantly has content that directly applies to what I am doing or figuring out. I just ordered a few different cutting board oils along with a bottle of mineral oil & wax to make my own. About a week ago I was in the hardware store trying to figure out which finishes were safe.
I was going to comment on that too. He must have a heck of a lot better set of teeth than I do if he can eat Tupperware(r). I can barely make an impression in the stuff, and only on the edges. 🤣
I have a can of "Tried and True Original" on order ... going to try it on turned items including salad bowls. It is polymerized linseed oil and bee's wax ... nothing else.
I love their line of finishes. The are great for bowls, cutting boards and spoons. I also use them for a lot of other projects. So nice not to have that solvent smell around when applying it.
If it’s a finish that dries with a hard surface like polyurethane or shellac it can chip as a knife is chopping on the board. I don’t want to be eating small bits of polyurethane.
hello . thank you for your video . got much clear picture now .I am a newbie to this industry . I started to work on drifting wood and turning it to a home decoration (indoor) . at this moment I am a little confused what finishing I need to apply. would appreciate your advice. and ... do I need to do additional treatment prior applying finishing? thank you in advance 🙏
Question: I was wanting to make a wooden mug for drinking purposes. I will most likely only do room temperature and cold beverages. Is there a wood finish that you would recommend for this purpose? Hopefully something that I would not have to constantly re-apply and will not dissolve in my drinks.
Tried and true because it actually cures for my boards. Mineral oil always weirds me out, hated how you can wipe it down and then more seeps out later, and it doesn't hold up to washing. I tell people to use butcher block oil and wax for maintenance since I know they can get it everywhere but I wouldn't use it myself due to the mineral oil but at least it has waxes. Thanks for the great video!
Is there a good finish for aromatic cedar that will keep it looking red used outdoor? Love your dry humor. And reading comments from other subscribers indicate a bunch of quality peoples in the world.
I have chestnut trees that I was going to make wood plates and cups out of for my son’s wedding. But someone said you can’t do that with chestnut because it has tannins. Can I seal it to make it food safe?
A hard film finish is a poor choice for cutting boards, if you actually plan to cut on them. The finish will scratch, and eventually chip. Mineral oil and wax is best for cutting boards, but it does need to be reapplied periodically.
i know this video was from 2 years ago but i hope you still see this question because i've been putting off a project for a while now. so my question is, what kind of wood finish would you recommend for a wooden kitchen counter (sorta like a counter, its a long table that covers one whole wall)? i'm looking for something that can give it a lot of protection from water since its going to be a cafe kitchen counter and need to clean it with water and soap fairly often. i just dont know which specific one will do, we dont mind if it stains the color too much since its not going to be out in the open and/or mess with the cafe's aesthetics. so long as it does then job and is simple to clean and maintain. (we're not treating the counter as a cutting board or anything, )
Thanks you - I will cite this *and* the CFR you linked to when the need arises. (I used to read CFR for medical devices a lot and that brought back old times👴)
"Now asbestos free!" Good knowledge, thanks! I always wonder about these things. Same thing with silicone caulk, though there's a bit more data on food safety there.
I would appreciate an update on this video. A lot of us are looking for finishes that are food safe and that are not a risk for micro plastics, especially for cutting boards.
I make it myself with food quality substances. My best results came from half beeswax and half grape seed oil. Lard will also work. Yes the oils/fats can turn rancid but if your wood spoons. and cutting boards complain you need better ventilation in the spray booth when using non-food finishes.
Ever try Velvit Oil? It’s a penetrating polyurethane based finish that supposedly hardens and reinforces the wood beneath it’s surface and won’t crack, chip, or peel. People have found it to be very useful on charcuterie and cutting boards as well as bowls, etc..
Great info, as always. and thanks for the FDA link. I have cedar raised vegetable garden beds and have been paying top dollar to garden supply companies for their food safe stains and weatherproofing finishes. It would be great to know if I can use something less expensive and more readily available.
Once again, great, concise, accurate information that needs to be heard. Bob Flexner has said this before, but it hasn't been widely heard. Keep up the good work.
While I believe Flexner is of the same opinion on this subject and I do greatly respect his knowledge on all things finishing (as I do other experts such as Charles Neil), I did not refer to his book when writing this.
A good example of what you are saying is urushi lacquer. The oils produced by the various urushi plants are extremely toxic and produce severe allergic reactions in most people. The North American urushi plant most Americans know is Poison Ivy. And yet the lacquer made from usushi sap has been used for centuries in eastern Asia. It can be found on a variety of items that have close contact with human skin or food, including fountain pens and expensive rice bowls. I can only guess at the amount of care required to safely produce and use the lacquer, but once the lacquer has been produced, applied, and allowed to cure completely, it is perfectly safe. And, when applied by a master, beautiful. richard -- Ah, those three little words so many people seem to have so much trouble saying: “I was wrong.”
Thanks again for another great video - learned something and free laughs along with it! What finish do you recommend for children's toys, that may be put in the mouth of a little one? Is a 'food grade cutting board wax' etc the best choice to be on the safe side? Or like you say, would any finish that cures hard like varnish or poly be OK? Thanks

As old mate was taking about his Beer mug I assumed you were to ( I still haven’t learnt that lesson yet “don’t assume anything “) wood is a reasonable insulting medium so I would highly recommend a wood hand carved mug finished with polyurethane. Please stay seated in the middle of the proverbial wagon so you don’t fall off , your times not up yet.
2:09 "Can plastics harm you? ... Sure, if you eat a set of tuperware bowls..."
That cracked me up.
My Tupperware salesperson says actually it shouldn’t be any problem, just chop it up into tiny bits…..just kidding!
My mind did go down the path of accumulated ingestion of microplastics, and I gather that is becoming increasingly problematic (I need to do more research), but I suspect us woodworkers are not going to be major contributors to this even if we do paint some finishes on our products.
There is nothing as refreshing on a hot day as a glass of shellac with a twist of lemon.
I find blonde shellac too weak personally. If you get something a bit darker and add some bee propolis with orange zest you've got yourself a treat.
I mean it is alcohol
Actually, if you like jelly beans, you've almost certainly consumed shellac.
Many candies are sealed with shellac, gives a glossy hard shine like what we use it for on furniture. Yup jelly beans and sugar babies.
I find the texture offputing unless it is thinned.
2:29 - "and you turned fine, right?" - l'm not sure about that, because of relatively long exposure, or when we are talking about long time effects, which cannot be tracked into single source, but it is made of many sources. And what side effects are yet to be discovered in the future.
Great commentary on wood finishes, your sarcasm is epic. Never stop.
I worry about the damage to the finish that will result with a well used cutting board. I have many wood and plastic boards and after a lot of use there is clear damage to the surface. So while contact with a hardened finish may be safe, after enough use that finish is going to start to come off in small pieces and get into food, and while likely small in quantity I think this is the real issue. Not so much a problem with serving ware that will not need to withstand abrasions. Washing and contact is one thing, but repeated cutting is different.
You will also be eating the wood flakes. Although microscopic pieces may not do any long term effects. I’ve had good results with mineral oil and have even used vegetable oil on cutting boards. Even washing them in soapy water, just rinse dry and when I think it needs another coat it’s easy to apply. A teaspoon of oil coats a lot of surface area. The newest reports say that millions of plastic nano particles are in a bottle of water and people are worried about a little flake of polymer.
A person must be very careful to avoid drinking anything they would not wish expelled through their nose while watching any of your videos.
Dean James Hamilton of Harvard Woodworking University with yet another graduate level course designed “to make you a better woodworker.” Works for me. Thank you James.
Thanks for the reminder, I remain amazed and how passionately some folks will defend products carrying the food safe label will defend said products as the only option for anything that might come in contact with food or children. Also thanks for the safety reminder at the end. Cheers from BC!
Even though finishes are contact-safe, there is something to consider when it comes to heat resistance & how well the finish holds up (some just don't). I wouldn't mind a video on which types of finishes hold up best with a hot plate on them, or when filled with boiling water as a wooden cup might be.
Avoid shellac. I made a trivet and tried that as the finish. It looked beautiful but the hot pots that got put on it eventually melted part of it. I sanded it all off and replaced it with my regular beeswax/mineral oil treatment for cutting boards and that's held up fine.
I second this request. My Dad used to make cutting boards as a hobby and used a finish that I don't recall off hand. I forgot the board was in the oven and turned it on to preheat. I realized pretty quickly when I started smelling the tell-tale smell of finish fumes. I pulled it out and allowed it to cool completely and then called my dad for his opinion on what to do. I left that cutting board alone for months before I used it again.
@@halsonger1317 Yea, I've been looking for a film finish that can hold up to things like that but they never seem to last very well. Oils are fine but it'd be nice to find something that can seal the wood pores, but with better moisture resistance than wax.
G’Day fellas , I made a hot pot board from many off cuts of ‘Mackay Cedar’ glued together with ‘Aquadhere’ and finished with ‘Cabots’ Polyurethane and it withstands large dishes of bubbling hot yummy food time and time again. It would be at least 4years old now and still good as. 👍
@@geoffbrumpton8544 Thanks; pity the brand seems hard to find here. Do you happen to know whether it was oil or water based?
"And you turned out fine right?"
Ummm I'm a woodworker and we are all a little off.
He only said that because he doesn't know me.
*"I'm not fine"*
Thanks for asking.
I was wondering why I live in sawdust.
Due all the saw dust and finishes
Define this state of "fine"... ;o)
I used 100% tung oil cut with citrus solvent on my butcher block countertops a few weeks ago . Outstanding so far, I'll keep you posted.
I have used Walnut oil - salad type from the grocery - on my rolling pins and cutting boards. It takes up to a month to "dry". I was told that the drying is actually a polymerization and oxidation process. It seems to resist moisture but I don't soak these things in water. Does darken the wood a bit to a pleasant brown color. It doesn't become sticky like the board that I used olive oil on (ti was a food preparation board that was not intended to be a treated board). I once used a raw linseed oil - not boiled - on a piece of wood; it takes a month to two months to harden but does soak about an eighth inch into the wood in the process ( I cut the board in half after drying).
Lots of options out there. Personally I use my own mix, a 'bees wax and walnut oil' finish for cutting boards, bowls, wood trays, spoons, utensils etc.
I'd love to hear more about what happens when the finish starts to wear down on a cutting board: does it ever end up in the salad I'm cutting, or does it always go down the drain?
I’ve been debating switching from the standard Mineral oil/beeswax finish for cutting boards for a while, but the ease and speed of application and maintenance without fumes keeps winning my requirements.
Just use raw linseed oil without turpentine then. Wax if you feel like it.
Or walnut oil, i prefer over linseed both from the perspective of colour and smell.
THANK YOU! I've been telling people this for years! On my cutting boards, I dilute wood bowl finish with 50% mineral spirits and let the wood soak it up with a few coats. Just enough to seal the wood without a build up of film. It works so much better than mineral oil and wax....
Useful information, well delivered. Thank you.
One point on finishes like polyurethane which form a skin. Knives will cut through the skin and so you can expect slivers to come off, and some will end up in your food - yummy! Once moisture gets under the skin, it's only a matter of time before the whole sheet peels away.
That's why I prefer things like waxes and mineral oil. Yes they might need reapplication, but that is pretty quick and painless.
Thank you. I agree-using a plastic film-forming finish is a bad idea on something like a coating board.
I'm thinking of printing the link to this video and place it on my cutting board tags, along with instructions to never put one in the dishwasher or into water for more than a few seconds when washing. Thank you for this video and here is a hearty AMEN!!!
Interesting. All told, though, I’ll stick with mineral oil for salad bowls and cutting boards. After 20 or 30 coats, I have found the wooden surface is essentially impervious to liquids. After use, wipe it out or off, apply another coat of mineral oil. Works very well on cheap teak bowls! Turns them into great presents.
i love your no nonsense common sense explanations, always simple and accurate, keep it up stumpy
Calm, sensible advice as always. One thing to bear in mind is temperature - hots food on cutting / serving boards could leach stuff out of the finish, so I agree, always check thoroughly. Those interested in BPA might be interested to note some epoxy resins contain it or it’s replacements BPF and BPS, but that’s a different story.
My go to food safe finish is a mixture of mineral oil and bees wax. I turn a lot of bowls and this finish really make the colors and grain pop. For reference, Bob Flexner wrote a book years ago and he states like you did that once cured, all finishes are food safe. Good video 👍👍👍
Love your videos. The information you’ve shared here is good. You are correct that the term food grade is misleading for things that can be toxic. What it actually means is that the product has been produced and handled in such a way that it will not transfer any contaminants that can get into the food. In the case of finishes it could be things such as metal shavings or even bird droppings. However it doesn’t mean that it’s safe to eat as you’ve said.
"And you came out fine, right?" Making a loooot of assumptions there...
Thank you for making this video. Your explanations are clear and succinct, every time I watch a video of yours I learn something.
So , well, thats bloody useful to know. Best woodworking videos on youtube by far.
Wow what a timing! I was trying to find info about tung oil as a food safe finish all day!
I’m in the coatings industry, and your videos on coatings are always spot on. Do you have a friend in the industry who helps you?
I often use a mix of beeswax and olive oil (20-25% beeswax to 80-75% olive oil), heated up to combine and apply when hot, so soaks in better. Very easy to apply, both products are edible "raw", and easy to re-treat later
Finally pulled the trigger on some isotunes. Thanks for supporting small businesses and your viewers.
My friend just got an oak table from his grandma. He used a card scraper to take off about a quarter inch of what looked like wax. She told him that she would spray Pledge on it every week for years. Yummy. Thanks for the great vids.
THANK YOU!!!!! I get this all the time with the resins I use. The finish is only as good as the cure and the person using the item afterwards.
So very helpful!!! Thank you! I forget the brand of “food safe” wood block finish I originally used but I liked it. Currently I go back and forth between mineral oil and watco butcher block oil and finish. The issues I have……….. not fond of the shiny finish, but on pieces that have high contact (spoon edges)… those contact areas get a dried out and worn look that the oil can’t seem to overcome. Just thought I’d share. Any feedback is highly welcome and appreciated!
Yep. In depth and informative. It's why you my boy blue!
Once again, clear and to the point.
What finish would you use for the inside of a pine hand carved mug so i can have my hot coffee in it ?
Hi, Any suggestion for a finish to put on plywood in a high humidity area? I am building a egg incubator so it has to be easy to clean and not off gas after it cures. Thanks.
I saw your comment below about mineral oil and I have to say that is the reason why I use and encourage new woodworkers to start with it: it is the easiest finish for a non woodworker to maintain, and you item can be used immediately. Also there is not any kind of smell or taste to the mineral oil (although that may just be me).
Yes, and mineral oil is one of the few things that won't turn rancid. That may not be an issue directly on the finish, as it may wear away before becoming rancid, but it will in storage. There was a time when you could buy 2 inch thick oak butcher block slabs from ikea for incredibly reasonable prices (15 years ago). So we replaced a sad old counter in our tiny old house with it. Once or twice a year I flooded the thing with mineral oil, letting it sit over night and wipe off. Treated it pretty much like it was impervious to damage (since it was so thick I could remove any actual damage). And it still looked basically new 8 years later. I loved it because I never needed a cutting board! I don't miss that house, but I do miss that counter.
This is a tough topic. I think you gave great advice with broad strokes. I am a Chef and one thing that is never brought up in these types of discussions are food contact surfaces.
In the health code there are two types of surfaces. Direct contact and indirect contact. It’s the difference between intentional and incidental contact.
Think of it this way if you are preparing food directly on it, that’s a direct contact surface. Such as bowls, cutting boards, pots and pans.
Indirect contact are things that food is not prepared on, but has the potential to come into contact with food. Things such as counter tops or your stove top.
Cleaning and sanitizing protocol is different for direct versus indirect surfaces. Our woodworking finishes should be thought of in the same way.
Personally I wouldn’t use a hard film finish on a salad bowl. Over time it could get brittle and chip off and go into your food. That could become a physical hazard (choking or cut your mouth).
Omg I was wondering exact that and from the comments you've been definitely reading our minds!
Very informative, you objectively provided concise and accurate data without shamelessly endorsing any one product.... oh, but wait! what's that hideous red thing on the bench? I kept waiting for a cunning smashy-smashy cut where a large leaf-shaped mass would crush that Red Wings cup-holder. My initial reaction was to question your credibility with that "not a nut comment", but the fact that you left it on the bench, where it belongs, shows that you are indeed a master of the wit, and a probably a Leafs fan at heart. Classic!
I still don’t know what to choose for finishing my cup…
Same way I solve many problems: I’ll just use what I have on hand. It may take awhile to dry, but you got me started knowing this finish will do.
You make nice educational videos! Compliments :)
As long as contact times and temperatures are small and low (as is the case with almost all household apllications of finished woods), your reasoning holds well. Just don't use a finished wood product for food storage (contact times < 1hr), and make sure the contact takes place at regular ambient temperatures or below, and the migration of any harmful ingredients, if present, will be negligably low.
It also depends on the kind of foodstuff the wood comes into contact with: watery, fatty, alcohol,... they all have different migration characteristics for different ingredients.
A bigger concern would be the wood itself. As a soft and "porous" material, it can easily be damaged beyond the finish (by cutting with a sharp knife...), and harbour moisture - and therewith bacteria - without the means to clean properly. That has nothing to do with the migration of chemical elements from the wood or finish to the food (which is the "food safe" criterion), but is the higher risk in the cutting board application. That is also the reason why we as European machine builders for the food industry are not allowed to use wood as the material to make any machine parts of (EU law differs in that respect from FDA CFR 21)
Where was this video 4 years ago when I made a butcher block countertop and after weeks of searching, purchased a "special" finish oil at $45 a pint!
It's almost creepy how this channel constantly has content that directly applies to what I am doing or figuring out. I just ordered a few different cutting board oils along with a bottle of mineral oil & wax to make my own. About a week ago I was in the hardware store trying to figure out which finishes were safe.
I want to do a acrylic paint pour on a rolling pin. I'm thinking rubbing a varnish on it is the best way to finish it. What do you recommend?
I’ve gotten more from your channel than any other woodworking channel. Thanks.
What is the best finish to use on a dyed wooden utensil to hold the color in? Like spoons and spatulas??
Excellent, excellent, excellent! I know it's been 2 years but thank you so much!
"Eat a set of Tupperware bowls". Thanks for the laugh.
I was going to comment on that too. He must have a heck of a lot better set of teeth than I do if he can eat Tupperware(r). I can barely make an impression in the stuff, and only on the edges. 🤣
All that "food" talk was already making me hungry, but the suggestion of eating Tupperware made me jump up and run to the kitchen!
@@ArTrvlr
The storage containers just sounded too good to pass up, huh?
@@thomasarussellsr Yummy 😋
I have a can of "Tried and True Original" on order ... going to try it on turned items including salad bowls. It is polymerized linseed oil and bee's wax ... nothing else.
I love their line of finishes. The are great for bowls, cutting boards and spoons. I also use them for a lot of other projects. So nice not to have that solvent smell around when applying it.
Use it as my primary finish on most everything. Love it.
If it’s a finish that dries with a hard surface like polyurethane or shellac it can chip as a knife is chopping on the board. I don’t want to be eating small bits of polyurethane.
Just what I needed.. As usual!
Thank you for the information. I am planning on making serving platters (charcutier) as presents this year and needed to know how to finish them.
I like the side discussion in the video on what finishes are potable
hello . thank you for your video . got much clear picture now .I am a newbie to this industry . I started to work on drifting wood and turning it to a home decoration (indoor) . at this moment I am a little confused what finishing I need to apply. would appreciate your advice. and ... do I need to do additional treatment prior applying finishing? thank you in advance 🙏
Excellent content and delivery as always. The comedic flair is always spot on.
Question: I was wanting to make a wooden mug for drinking purposes. I will most likely only do room temperature and cold beverages. Is there a wood finish that you would recommend for this purpose? Hopefully something that I would not have to constantly re-apply and will not dissolve in my drinks.
I am building a wood roof for collecting rain water which will be filtered for drinking. Is a pine tar turpentine mix recommended? Thanks
Tried and true because it actually cures for my boards. Mineral oil always weirds me out, hated how you can wipe it down and then more seeps out later, and it doesn't hold up to washing. I tell people to use butcher block oil and wax for maintenance since I know they can get it everywhere but I wouldn't use it myself due to the mineral oil but at least it has waxes. Thanks for the great video!
What would be a good finish to put on a double to make a candle out of it
Is there a good finish for aromatic cedar that will keep it looking red used outdoor? Love your dry humor. And reading comments from other subscribers indicate a bunch of quality peoples in the world.
I have chestnut trees that I was going to make wood plates and cups out of for my son’s wedding. But someone said you can’t do that with chestnut because it has tannins. Can I seal it to make it food safe?
You're my go to tool guy since I've gotten into wood work
Brilliant video James. Very informative and certainly made the choices a lot clearer. Thanks.
A hard film finish is a poor choice for cutting boards, if you actually plan to cut on them. The finish will scratch, and eventually chip. Mineral oil and wax is best for cutting boards, but it does need to be reapplied periodically.
Thanks for replying to my question on todays video on Tung Oil with this video. As usual, great information. Thanks
i know this video was from 2 years ago but i hope you still see this question because i've been putting off a project for a while now. so my question is, what kind of wood finish would you recommend for a wooden kitchen counter (sorta like a counter, its a long table that covers one whole wall)?
i'm looking for something that can give it a lot of protection from water since its going to be a cafe kitchen counter and need to clean it with water and soap fairly often. i just dont know which specific one will do, we dont mind if it stains the color too much since its not going to be out in the open and/or mess with the cafe's aesthetics. so long as it does then job and is simple to clean and maintain. (we're not treating the counter as a cutting board or anything, )
A good quality oil based polyurethane. I have a video on it if you search my channel page
Thanks you - I will cite this *and* the CFR you linked to when the need arises. (I used to read CFR for medical devices a lot and that brought back old times👴)
Thanks for the video. This is something I have been trying to explain to people for the last 20 years. Now I can just send them the link.
"Now asbestos free!"
Good knowledge, thanks! I always wonder about these things. Same thing with silicone caulk, though there's a bit more data on food safety there.
I've never laughed more from a Stumpy video than this one. 1:55 , 2:08
Thank you for this useful and good information.
Legend! Was just looking into this and a little confused with the outcome of my research! Great video, thank you!
I would appreciate an update on this video. A lot of us are looking for finishes that are food safe and that are not a risk for micro plastics, especially for cutting boards.
I am doing a cedar wood kitchen table for outside. What is the best sealer for that?
Hope another behind the sawdust comes out. Stumpy and Mike crack me up.
I've said this for a long time about finishes that dry but others have said no it has to say food safe! TFS, GB :)
I make it myself with food quality substances. My best results came from half beeswax and half grape seed oil. Lard will also work. Yes the oils/fats can turn rancid but if your wood spoons. and cutting boards complain you need better ventilation in the spray booth when using non-food finishes.
Ever try Velvit Oil? It’s a penetrating polyurethane based finish that supposedly hardens and reinforces the wood beneath it’s surface and won’t crack, chip, or peel. People have found it to be very useful on charcuterie and cutting boards as well as bowls, etc..
This clears up a lot of confusion I had about food safe finishes. Thanks for sharing this information.
Great info, as always. and thanks for the FDA link. I have cedar raised vegetable garden beds and have been paying top dollar to garden supply companies for their food safe stains and weatherproofing finishes. It would be great to know if I can use something less expensive and more readily available.
Once again, great, concise, accurate information that needs to be heard. Bob Flexner has said this before, but it hasn't been widely heard. Keep up the good work.
I kind of feel like he's been reading Flexner's "Understanding Wood Finishing" and making videos on it as he goes through it, which isn't a bad thing.
While I believe Flexner is of the same opinion on this subject and I do greatly respect his knowledge on all things finishing (as I do other experts such as Charles Neil), I did not refer to his book when writing this.
Thanks! Does anyone have recommendations for a stain? I want to change the color of my project that will contact food stuffs.
Excellent. How often would one need to re-apply vegetable oils such as olive and walnut?
Thanks for bringing some common sense, along with some levity, to a contentious subject.
A good example of what you are saying is urushi lacquer. The oils produced by the various urushi plants are extremely toxic and produce severe allergic reactions in most people. The North American urushi plant most Americans know is Poison Ivy. And yet the lacquer made from usushi sap has been used for centuries in eastern Asia. It can be found on a variety of items that have close contact with human skin or food, including fountain pens and expensive rice bowls. I can only guess at the amount of care required to safely produce and use the lacquer, but once the lacquer has been produced, applied, and allowed to cure completely, it is perfectly safe. And, when applied by a master, beautiful.

Ah, those three little words so many people seem to have so much trouble saying: “I was wrong.”
Educational is an understatement. Best explanation ever!
Thanks again for another great video - learned something and free laughs along with it! What finish do you recommend for children's toys, that may be put in the mouth of a little one? Is a 'food grade cutting board wax' etc the best choice to be on the safe side? Or like you say, would any finish that cures hard like varnish or poly be OK? Thanks
I know what I would do, but when talking about someone's child, I think it is best to direct you to the FDA.
Another great presentation. Covered all the bases and scored extra points in my book.
