Don is absolutely right. Now if you are careless, and you have one of those razor blade scrapers where the blade goes into a metal clamp type device you may scratch the glass with the part the blade sits in. In other words, the blade slides under the clamp, and now you are scraping with the clamp and not the blade. That blade has to be secure in the clamp, especially those scrapers that retract the blade, or the ones that use a screw to secure the blade.
Glass can degrade a razor leaving behind marks of steel if it is rough enough though. That can be interpreted as a scratch but wiping it away would show the steel being ground off in this case. If you made textured glass you could sand away steel, for examole.
You are correct razor blades will not scratch the glass but sometimes people think a utility knife blade is a razor blade which it is not a utility knife blade will scratch the glass. We had a construction site that was just finishing up with the final clean and there was some shipping material on some partition glass for a conference room... The laborers used utility knife razor blades out of the utility knife instead of straight razor blades and they scratched the glass $25,000 later the glass was replaced... It seems that the corner point ends of the utility blades scratched and etched the glass.
I used glass on my light table for graphic design, paste up, cutting paper with a xacto and single edge blades and the blades did not scratch the glass. It must have been tempered glass, like fish tank glass. So I agree.
One other guy kinda mentioned the crap on the glass during manufacturing. I have a slightly different theory... If you have scratches already on the glass anywhere... There are tiny almost microscopic fragments of glass in that scratch-so when you run over the scratch with anything, it can potentially pick these fragments up causing more scratches elsewhere. I switched from different glass cleaners because of old scratches, to razor blades and I still kept finding more scratches. So yeah not the blades fault.
Great point dan i agree alot people forget most tap water contains calcium particles either from lime deposits from our aquifer here in florida n know for a fact build up calcium particles from hard water will scratch glass not the razor.but thats just my observation
I’m pretty sure I have, I was scraping glass at a pretty steep angle, it slipped and jumped along the glass and left a line of chips that looked like a scratch. It wasn’t a normal scratch but same result pretty much.
This is hilarious....we were just cutting some new backgrounds for Jack’s new tank and I was showing him this as I trimmed the tape to hold it on and explaining this to him and then your video popped up and he was like....wow you’re right dad....and I was like....of course son, I’m always right hahahaha....then he ran a razor across the glass like 10 times and was so impressed....hahahaha....perfect timing Dan....👍
When I worked I construction way back when guess what we used to clean the new windows......... wait for it, wait for it, we used razor blades. Great video Dan you are exactly right on this one. Thanks for putting it out there
I totally agree .... I use a razor all the time to get that stubborn algae off the glass. I scrub old glass down with wet wire wool to clean it before i construct a tank. I have never scratched a glass aquarium in this way .... Plastic and perspex tanks are a different kettle of fish though.
I agree with this video dan I use a razor so many times and never scratched my tanks glass and the people that scratched there glass with a razor then they don’t know what they are doing
Does the dried food scrape the glass, with the razor? I wouldn't buy the cleaner with the razor blade, just cleaned my stove, have the marks still there! You had a great video, thanks, now I want to buy the other cleaner, with the razor!😅
well, then, tell that to OLFA. They make stainless steel snap-off blades specifically for glass because the regular steel blades can and do scratch/score glass very easily. This is an especially serious issue for window tinters across the globe. But I DO AGREE that it is the (manufacturing) debris on tempered glass that does the scratching. But most all OLD tempered glass - pre-1990's- including my old aquarium do not have that issue. That's my 2 cents worth from 35+ years tinting auto's, homes, farm equipment, RV's, commercial buildings, boats, etc, etc...
point 1. diamonds are cut with steel blades. it is not just a question of hardness. point 2. tempered glass has fabrication debris weakly fused to the surface as a consequence of the manufacturing process. This debris is dislodged by the blade and gets dragged around by it viewswindowcleaning.ca/2017/12/03/will-razor-blades-scratch-windows/
Yeah razor blade won't scratch glass. But if there is a laminate or film then you can scratch the laminate or film but not the glass. Between that and partical, I think is where the confusion comes from.
I'd say only 0000 steel wool pads. I've seen higher leave micro scratches in the glass. I'm not saying it was necessarily the pad but having been taught by a glass cleaner I was told 0000 will polish glass anything else could leave the micro scratches
Carbon razor blades absolutely can scratch glass! The carbon carbides in the steel are harder than the glass. Happens from time to time when everything is just right. Never happens when you try to make them. I'm sure the next one will hit home very well for most. Look what happens to your car windshield when you don't run wiper blades the steel arms will wear right into the glass. Along with that, the wiper arms are not even as hard as razor blades.
Hahahaha. I work in the sign and vinyl installation field. And stainless steel razor blades are what they use to DIRECTLY cut vinyl on glass. Hell I use them to clean my glass top oven too
Very fine dirt particles can do it. Same stuff that makes it into your pocket and leaves tiny scratches on you phone screen. I was taught by my dad how to clean glass with a razor blade (used to be a professional glass cleaner). I do it at work when rooms are remodeled. Now there is concrete dust from when they smoothed the concrete subfloor mixed in with the tiny paint specks on mirrors and such in these rooms so you have to be very careful, keep the glass and blade lubricated and wipe things clean often enough you don't scratch it with the concrete dust, but my boss told me not to use a razor blade to clean the glass, so I cleaned the glass with one in front of him and after cleaning it pressed the blade as hard as I could into the dry glass and scraped it to try to scratch it. Dulled the blade to the point that I could press it into my thumb and slide it across without cutting it and then asked how the razor blade would scratch the glass.. he just looked at me kinda dumbfounded
Dan said the FastOrange in that soapbox will scratch the glass before that razorblade will...LOL. I feel you brother, that's one reason I've never started a YT channel... I'd just be arguing with comments all the time.
No you can't scratch glass just scrubbing the algae off but if you where to fire a razor blade out of a cannon/gun at 700 mph at along a pane off glass it will indeed scratch glass.
I doubt the iron oxide would scratch it, but I'm not sure about that, as I've never looked into it. I use them once then throw them away just because they rust so quickly.
All the scratches in all my 'used' tanks were there when I got .it. *I swear* I have scratches on the outside - on the front - that I didn't notice until after my friend left -after helping me lift the tank onto the stand.- - - So now and then, I draw a line on the scratches with a white candle, then buff it with a soft cloth. poof. ooo fish Love your videos and insight Dan. Oh, and can I mail you plants?
You can try. I don't know how well they'll do in my tanks. I still have plants someone else gave me in a bucket in my bathroom. Lol danielhiteshew@gmail.com
Nice video and take. I always know people who argue with me telling me I'm wrong, be it cleaning glass, my area of expertise, or even politics, are the ones who won't even take the time to research what they're arguing about to learn the truth. Their arguments are always emotionally based and not on facts. I always say to them that I guess facts don't matter. Please people, for all humanity, and those of us that do research what we're talking about, if you're going to accuse someone of being wrong or take a strong stance on something, just be a rational and honest person and Educate yourself. Who cares if you were right or wrong before you did your research? As long as you know the truth. Anyways, sorry about my rant. Nice video, and I don't even like fish, lol. Was just researching the topic to Educate myself.
You are forgetting the difference between hardness and brittleness plus pressure. Both the razor and glass are not perfectly smooth, each contains imperfections which are really viewable under a microscope. You are correct in saying the soft razor can't scratch hard glass, but you are forgetting the difference between a scratch and a gouge. As the soft razor wears out, it's imperfections will increase. Combine these imperfections with those of the glass, and the soft material can shear the hard, brittle material. Even "gentle" force on a microscopic imperfection will shear it off, and the soft razor, under pressure, will have no trouble finding those groves and amplifying them. You're calling it a scratch, and what you say is true. The correct word is "gouge", and most people would call it a scratch. So it's true that soft steel can't"scratch" hard glass. But it's not true that soft steel can't gouge hard glass. Hardness is combined with brittleness. The soft steel will fill these imperfections and shear, rather than scratch, the brittle edges of these imperfections.
@@DanHiteshew-oneandonly Are you trying to claim that a softer material can't gouge a harder material? Did you even know the difference between a scratch and a gouge? Keep on keeping on, my man. Love your confidence.
tl;dr: flawed arguments. i can be 85% sure razors can scratch glass Being hired as a professional window cleaner, I have used razor blades to remove stickers off windows a good couple of times, and I've also had a short go at removing industrial material that gets on the glass (in my case, silicone - which when it comes to windows, is a stupidly sticky glue which is very very difficult to get off.). Now, I have yet to scratch glass (and hopefully I never would,) though my boss taught me that it's important to lubricate the window well (with soapy water), and to scrape at a good angle, and to not use much pressure, all so that the blade doesn't sudenly stop and therefore go at a sharp angle at the glass - as then the glass would be scratched/cut. Also, my boss mentioned we can't use razor blades on all window like surfaces, such as mirrors, low quality glass, and some other stuff. I don't remember the reason but it was probably something to do with the glass simply being very cheap, and therefore very easy to scratch. And when you criticise window cleaners blaming the razor blade for when concrete scratches their windows, well it's fair to blame the razor blade. The reason is that the razor blade did a insufficient and flawed job at effectively removing the concrete, ultimately resulting in a scratched window. Had the cleaners used some corrosive chemical or something instead, then the concrete would be removed and there would be no scratches. And so when cleaners hear people say "razor blades don't scratch glass", they'd immidently say otherwise since evidently using blades on windows, one way or another, may leave you with scratched glass. Also your foundations for this claim seem poor - sounds like you just use your razor on your high quality glass of your aquarium, and hear about other stuff via internet - which is that "since razor blades aren't as tough as glass, it is physically impossible to scratch glass with a razor blade". Which of course sounds like a stupid claim - how can some material be impossible to scratch glass? I tried just then to scratch my glass desk with a razor blade. I was unable to scratch it a traditional way, although I did for sure scratch the glass when slicing the edge of the glass. Which sugests that a razor blade will have a difficult time scratching glass, though it's still possible to do. And also that low quality glass is very likely to be heaps more susceptable to scratching.
I use cheese on my glass all the time, it leaves a lot of scratch marks :( 😂😂 Just kidding, but razor blades are fine, maybe some people are too rough with them?
I know using a razor blade is effective for cleaning glass, but I disagree with you. Soft materials can most certainly scratch a harder surface. Here are some examples: A rubber fan belt on older cars is softer than metal, but 100,000 miles of driving, and the rubber fan belt will scratch components of the motor if the belt rubs it.

Fiddle players can comment on this, I don’t know much about it, but damage is done to the bow and the strings when they play.

(Have not seen in person, studied about it school tho) Magic erasers for cleaning granite counter tops... polishing cloths on metal or brass... Leather belts or horse saddles on metal buckles.... Fishing line on rod and reels... Chain and sprockets on dirt bikes..(both chain and sprocket take wear over time, no matter which metal is used for chain and which metal is used for sprocket) But more factors are at play in the exceptions I mentioned, including weight, density, force, time, and friction... others as well. they key take away is under "normal settings"

If your glass is tempered, your blade will scratch it despite what someone told you.
I was still thinking that a razor on edge could scratch, so I took a razor to some glass. It was futile.
I used glass on my light table for graphic design, paste up, cutting paper with a xacto and single edge blades and the blades did not scratch the glass. It must have been tempered glass, like fish tank glass. So I agree.
Graet video. In the middle of cleaning my aquarium. The build up on top of glass cover needs a blade to remove that stuff! Thanks

Lol I guess I should have pointed out that I was only talking about glass, not plastic tanks.
That would make all the difference. Acrylic will get scratched!

Use a Tunze Care magnet. It doesn't pick up the substrate and wont scratch your glass.
Informative upload, Thanks, Dan👍🏾.
I have stainless steel blades, will they scratch the glass because they are not razor steel?

I am so confused. I used a razor blade scraper to remove window film on a residential window, and there are scratches.
You can get contaminates on the glass that get dragged by the blade, but the blade itself won't (can't) scratch glass.

I doubt the iron oxide would scratch it, but I'm not sure about that, as I've never looked into it. I use them once then throw them away just because they rust so quickly.
if its not the razor blade then what is it cuz it happens when you use razor blades i have seen it on 100's of tanks
and it has NOTHING to do with substrate since there is none on the outside of the tank
I don't know what it is, but it's not the razor. (I seriously doubt you've personally seen it on "100's" of tanks. Lol)
Maybe calcium or lime build-up on the glass? Hard water will leave deposits that can scratch glass.

Fiddle players can comment on this, I don’t know much about it, but damage is done to the bow and the strings when they play. Like extreme fiddle, “devil went down to Georgia” etc.
Tires from vehicles damage pavement. Not sure if it qualifies as “scratch” ... but definitely dents, chips, crushes. Weight is a factor here, like your Ax example. And hammer example.
Then supernatural situations: tornados have been known to take soft objects, like pine straw, and pierce glass or metal. (Have not seen in person, studied about it school tho)
Magic erasers for cleaning granite counter tops... polishing cloths on metal or brass... Leather belts or horse saddles on metal buckles.... Fishing line on rod and reels... Chain and sprockets on dirt bikes..(both chain and sprocket take wear over time, no matter which metal is used for chain and which metal is used for sprocket)
But more factors are at play in the exceptions I mentioned, including weight, density, force, time, and friction... others as well.
