- MIke shows how stones are cleaned with muriatic acid. All my videos are my ways and ideas, I always suggest anyone doing any type of work to consult professional help.
Beautiful stone work, Mike.
thanks, Mike, my brothers job, I appreciate it. mike
Mike,nice looking stonework! one mason to another.
thanks, I appreciate it. mike
I had a sister in law that was giving me a hard time because she didn’t know you could clean the haze. I snuck up a few days before they got to the cabin and did use acid but very diluted. It was the only time she almost was wrong until she saw the hose wasn’t coiled.
That’s a a great line about your brother.
Thanks Jonathan, Mike
This is great video. Not instructional but helps a lot.
Thanks, Mike
Mike, I love it when I look up something and your name just pops on up lol 😅👍
Thanks, I appreciate it, Mike
so I know you have been doing this a long time and have experience. something you might want to consider is adding your acid to the water. it's a little safer that way. thanks for the video. Cheers!
thanks, I did say that thought, thanks again, mike
+Mike Haduck my mistake, I missed that.
Thank you for the demonstration and its effect on soft brick! I had no idea! Now i know! :)
Thanks, Mike
Just a tip; for minor to average mortar cleanups on aged brickwork, use an electric power- washer(1500-1800psi)concentrating the wand on the 'bricks' (not on the grouting). It's fast & no acid or chemicals, just H2O!
Hi Jeff, I appreciate it. mike
Gee whiz Mike. Acid is apparently a potentially touchy subject...Thanks for all of your great videos~instructional and otherwise. Hope you are well.
Hi W Tango, yes it is, best to be done by those who use it regular. thanks mike
Mike commented to me yesterday. He doesn't recommend acid. For cleaning.
Never add water to acid. ALWAYS add acid to water to avoid violent reaction.
I said that, thanks mike
water was added to the acid in this video.....
@@MikeHaduck You said it, but you didn't do it.

Nice video!
Thanks, Mike
I have a newer natural bluestone patio (a year old) that now has what looks like dark black embedded stains only on one paver. All the others look normal. Also some rust spots. Would this method work to clean those stains or should I try something less invasive? Regular outdoor cleaners did nothing.
Hi Michelle, natural stone bleeds for a while, I am not a fan of using a acid, I would just try some water and stiff scrub brush first, acid could cause more damage then what your trying to fix, thanks Mike
Try a pressure washer. I pressure wash my stone patio one a year and it makes it look like new.
i have this type of stonework/paving on a huge interior wall. the missus is giving me continual grief cos its filthy and impossible to clean with hands and brushes etc. Maybe I will try an acid wash, do you reckon acid or sandblast? I havent used a sandblaster and not sure if practical interior options for that
I only showed how someone used acid on a outside project, I can not say how anyone should do it where or how, I hope it helps, thanks mike
Sand blasting is very messy outside of an enclosed space.
After reading some of the comments here
I think people stil did not learn how to read
He said it 15 million times
This is NOT a how to video
Thank you I have wood stain droppings on my pavers. how can i clean that?
Hi Miximus, maybe a solvent, steel brush, sandpaper, rub some mud in it, whatever works, thanks Mike
I had a guy regroup my bluestone patio and he left a mess. Mortar all over the place. What is the best way to clean it off?
Hi Lucid, you got to be careful bluestone is very soft, sometimes a scraper and a good scrub brush and plain water will do the trick, thanks mike
@@MikeHaduck I’m going to start easy and see what happens. Thanks!
It's much safer to add acid to water than water to the acid.
very true, and it was explained why we did it the other way. But Good point for everyone to remember. thanks mike
Andrew Bent Exactly.
Wrong. Always pour the acid in first. That will mix it up. Just wear glasses and gloves.
DUH!!!!!

😄😄 another Einstein ..
does the Muriatic acid also clean up mortar/concrete residue? my mason did a bit of a sloppy job on my wall and I need to clean it up, thanks
Hi Gus, it all depends on how much, it's a hard call, thanks mike
@@MikeHaduck thanks for the reply Mike, it's not a lot just smears here and there almost like a paint layer thickness, you know the usual smear around the joints, nothing that could be chiseled out.
you never want to stand over acid when applying it or poring water to mix it without a respirator
+Anthony Mcgavin I agree, thanks mike
Would this approach work to get grease stains off of stone counters in my outdoor kitchen?
That is something I can not comment on, I would ask the counter guys, thanks mike
Use detergent for grease. Acid removes mortar haze because mortar is a base (alkaline).
What do you recommend to clean off chalky white residue on brick from old plastic window shutters? It doesn't appear to be paint per se, it appears to be resin pigment run off from the plastic itself (the shutters were not painted, they were white vinyl)
Hi Medic, I would say it all depends on the brick, there is nothing specific I could recommend, trial and error, thanks mike
tell your bro wear some gloves , it's acid can't be good for your hands over time.. great video thanks
I will tell him, thanks mike
Gloves only fit on your hands...
Joel why don't you make a video entitled " The acid police?"
Some stones like what stones ? Can I clean my culture stone with it to remove excess mortar ?
Hi zac, I never use acid on fake stone, fake stone us cement itself , I heard of peopke doing it and it ruined the whole job, thanks mike
@@MikeHaduck no the culture stones I have are not take , they're the stone panels
Can I use muriatic acid to clean real coral stones on my exterior wall of my home? They are some areas that have mildew and algae. I already tried bleach but that didn’t work. Any advice I would really appreciate it.
Hi Robert, coral is soft, and I am not a fan of acid, if I don’t have to use it, I always do a couple samples first,n. Thanks mike
Mike Haduck Masonry Thank you Mike.
Good evng, can some one give quation for per sqm for acid wash for stone masonary.
Thanks.
Hi, I rarely use it, I would check with the directions, thanks Mike
Okay so I'm trying to Clean
Effrolecsence off a 12in split face block wall I've used SureKlean 600 NMD80 Ef-Fortress and more nothing has done the trick and Unifrax is on my ass any suggestions?
Hi Mark, usually if is does not come off with soap and water then water is getting into it and or behind it and it is always gonna keep coming back, I did a video called "Efflorescence what is it, (mike Haduck)" that is all I can tell you, mike
Mike Haduck well I mean I've used so many different acids and pressure washed it nothing's working
You haven't sealed it have You? Most manufacturers recommend waiting 90 days prior to sealing. It takes a while for that efflo to seep and block to to cure. If you did seal, you're going to have to strip it. Techniseal makes a great efflo remover.
Hi Dana, I am not big on a sealer for real stone or brick, sometimes it traps the water in, especially when it lays flat, every job like chimneys are different,,, everyone has a different opinion, I hope that makes sense, thanks mike
Will this work getting non-shrink grout off bluestone? We HAD a gorgeous walkway my husband fixed (cracks and chipped out mortar) but now most of each stone is covered and looks awful.
By the way, he has already sealed it too. HELP!
Hi Carol, it’s a hard question to answer, if it does not come off easy with a scraper wire brush and a hose, you could grind it , maybe acid, but, I really cannot say anything will defiantly work, mike
Mike Haduck Masonry thank you for your fast response! I’m sorry to say he’s already used a power washer on it and nothing budged 😫! I’m afraid to use the acid personally, I’ll try a scraper and wire brush first. Thanks again.
Did you take this tank with clear hands right after it was filled with acid? :)
+Boby Bob I just filmed what someone else was doing, I don't really use acid, I guess it depends on the job. thanks mike
Bob your comment doesn't even make sense...
Hey Mike so what do you use on smaller jobs then if not acid?
Hi A.K. I just keep it clean and hit it the next day before it gets too hard with a hose and brush, thanks, Mike
@@MikeHaduck ah I'm dealing with removing remnant stucco on 100yr old brick that definitely wasn't glass surface as it may have lost its fire skin but can't determine without removing paint and debris safely
You should never pour muriatic acid first and then water. It creates fumes and high temperature from the reaction splashing the acid out of the container. I learned that in a chemistry college course.
+Ruben Arias I thought I explained that, thanks mike
@@MikeHaduck Geeezzzzee, how many acid" arm chair quarterbacks " can there be? Crap, the guy can mix it like he wants to.........
Hello i am from india
I'm Hubble request to u plz suggest us acid or chemical
to remove cement from natural black basalt stone and give a natural shinning to stone.
Hi Ravi, I can't say, every situation is different, acid can cause a lot of damage I would try other ways first, thanks Mike
I have effervescence leaching from my Stonewall, was thinking of trying this, have you had any experience with this problem
Hi John , check out my video "Efflorescence, what is it? (Mike Haduck) I think it will answer a lot of questions, thanks mike
Use a wire brush to scrape it off. Then make sure you have a proper cap over the top and a drip edge cut in so water doesn't run down the face of the stone. Most often, efflorescence occurs when water saturates.
Can Mauriac acid be used on colored pavers that are faded to help revive their color? Have a red and gray pattern paver walkway and backyard and they really need reviving?
hhova29 I never used it on pavers and because they are man made I would be very skeptical. maybe do a test on a old one. good luck ,mike
What do you do if the stonework is indoors and you don't have the ability to spray everything down with water?
Hi Joseph, I never had to do it indoors, I always cleaned as I went, thanks Mike
hey thanks for uploading this , i do quite a bit of masonary work and i always wondered how you use this stuff I have a few bricks i want to clean the mortar stain off ,l Layed the bricks a couple months ago you think it will still work??
I would do a couple samples with some old brick first so you know what happens at the end, too much will burn and too little will do nothing, some stone and brick you can not use acid, I rarely use it myself, thanks mike
if you mix masonry cleaner with root killer can it corrode metal? I think one of them contains copper sulphate and the other phosphoric acid. I'm not 100% on this 'mythbuster' but I'd appreciate it if someone could reply
I don't know much about that, but I seen when I left a shovel in the acid it would rust, thanks mike
"You're gonna wanna use some eye protection, hand protection, and breathing protection."
Guy in video: "I'm just gonna walk into my spray direction and give a hard brush of the acid-sprayed surface right in front of my face"
Thanks, Part 2 ,is better, Mike
HI.. Isnt best to add the acid to the water.... NOT water to the acid because of splash.... IMO
YES< YES< YES>>>>>>>>>>>>>>>>>>
Somebody took chem 101
No. Add the acid first. Take care when adding the water which will help mix it up. Wear gloves and safety goggles.
That's Exactly How I Do it Except I Always Add Acid to Water Not the Other Way Around. I Also Shake Up the Mixture in Sprayer. I Noticed it Didn't Fizz Up Much on Cap Stones But Fizzed Up Like Crazy on the Rest. Acid Washing Chimneys Makes a Cloud of Acid Gas.. Sometimes You Come Around the Valley & the Fumes Make You Choke.. That Can't be Good for You.
Thanks John, mike
Well John, why don't you make a video instead of pester Mike?
Posting a Comment isn't Pestering.. People Have the Option to Turn Comments Off if they Don't Want to be "Pestered" By Them..Why Would I Make a Video When Mike Does Such a Good Job of it.. I Dunno if you Ever Got Choked By Acid Gas Coming Around the Back of a Chimney But it's Something I'm Careful Not to Do Again. Why Are You Pestering Me Over a 2 Year Old Comment Jaggoff!?
@@johncrowe5164 John may I pester you to use a respirator it is highly recommended & stay well.
how do you remove what looks like a bleach stain on ceramic tile thanks
that would be hard to answer, It could be anything, I really never cleaned tile., thanks mike
can I use this product on pebble stone tiles
hi alan, I would do some test first, every product is different, check out part 2, mike
now add some wet look sealant & it will look awesome!
+Juan Fraire thanks mike
Mike Haduck Mike maybe you can answer this. I recently had some laja stone set on a walk way.the constructor put an excess amount of grout and is all over the stone. Will the muriatic acid work to clean it off or should I just use an iron brush?
+Juan Fraire like the video says some stones you can't use acid on. I personally very rarely use it. every situation is different, so I wouldn't dare to answer, I would probably do a side test on some of the extras to make sure, thanks mike
Mike Haduck tried acid didn't work i'll just grind it off thanks mike!
What is the mixing ratio?
Hi Ram, it's best to follow the directions on the container, mike
How we can polish black rocks for original shine
Hi Waheed, I really can't answer that, maybe a buffing stone, thanks mike
U build the bench?
It was my brothers job, I was just helping, thanks mike
How about on pavers?
Hi John, I never used it on pavers, only for new brick or stone clean up, thanks mike
What if the brick is in a building that can't be flooded with a hose?
HI Karen, I can not comment on that, usually it is done well before the house is complete, I hope it helps thanks mike
Then you're on you're on, lady.
Every instruction I had ALWAYS said to pour ACID into WATER, NOT VICE VERSA, regards
that is what the video said, thanks mike
then it should have showed in that order! regards
😊
Thanks , Mike
Spraying water into acid at pressure...Insane. Where's all your body protection.
Thanks David, mike
David, none of your business...
The acid will destroy any metal inside the sprayer head, spring. I know.
Thanks Kenny, mike
Mike knows that.........Now tell Mike " how acid can spill" then go on and troll someone else..
You look good
thanks ouchen, I appreciate it. mike
You told me two days ago. You dont recommend any acid at all
Hi Jerome, that's true, last resort, on most big industrial jobs you dont have a choice, but you got to know what your doing, thanks mike
@@MikeHaduck Went got a couple chisels from your recommend. Started at it. Almost done. Swollen thumb. Ouch
My hands burn and hurt watching. Insurance adjuster alert for hand problems.
Hi Mike, I almost never use acid, too many things to go wrong, thanks Mike
This is just plain old HCL aka Hydrochloric acid.... it is just one of its other names ..... dont be fooled into believing it is anything special.
thanks Steven, I appreciate it. mike
Seriously? You add acid to water, you NEVER add water to acid. Standing above that mixture is a big no no as well. That vapor tears into your lungs.
Thanks Brian, I'll try harder, mike
All good man, your masonry work is beautiful! The problem with adding water to acid, it creates a vapor that can really damage your lungs, especially if you are above where you are mixing the two. I use about 5 to 1 water to acid and would never walk on the acid solution with leather boots since they absorb the acid. Your work is amazing though, you should be very proud of your skills.
Thanks Brian, mike
There's hardly any change on the topstones. Seems pointless there and a bit of overkill for the messy pointing which could have been pressure washed to clean too I think
Hi Peter, the laziest man always finds the easiest way, pressure washing ain't as good as everyone thinks and sometimes causes a lot of discoloration and damage, thanks Mike
Well, then why even reply, Pete?
You and your brother sound the same.
+Murray Hart yep, we is from the hills of PA. LOL. Mike
Yeehaw!
Thanks Sudo, mike
Pre soft wash days
Thanks , mike
so much for acid to water
This video is completely pointless! Doesnt show anything in detail of why its used, really doesnt show anything do before and after, and doesnt really even state why you use this stuff. waste of time!
+Brandon Fuller I did the best I could with what I had at the time, I will try to do better. God Bless. mike
brandon, you sir are a waste of time
Please wear gloves geeze
thanks for the tip, mike
Why? what good are gloves going to do.
My toes and lungs are burning... Should of wore your gloves,

+Captain Hook . I guess everybody got their own way, thanks, mike
You must be from the South (with the God Bless You bit) Take the darn thing dow before you hurt someone!
@@bostonw2102 no shit bro. Acid ain't no joke
Add acid to water always. Never add water to acid. Pretty basic stuff.
Thanks, mike
So you're a member of the acid police, Konak?
Acid to water not water to acid🙈
Thanks, Mike
He can do as he pleases....Who are you? The acid police?
Not a good video for beginners.
Those acids are very dangerous, so gloves and boots are really necessary.
Hi Dino, check out part, it is a 2 part series, thanks , mike
Dont be such youtube cops with the gloves folks they are his hands not yours. Sheesh and it does not matter how you dilute it as long as its mixed it is a non explosive product .
Bare hands no mask
Thanks, Mike
this guy has been doing it wrong for a long time. lol.
Thanks Powerstroke, Mike
No safety wear
I use it, thanks Mike
Glad you can see good, kid wood.
Water first wow.
hi curtis, I commented on that, thanks mike
OMG cannot believe these guys are foolish enough to use acid without proper Personel Protection equipment like Googles,Gloves,long sleeves and walking on the wall whilst spraying it.
Do not not use acid like this please.
Thanks user, I will tell my brother, thanks Mike
This guy gave up on life lol. That's acid bro
hi Anthony, just filming the real world, thanks mike
LOL using acid will kill any vegetation for 3 feet wide and 2 feet deep for up to 3 years, it would have been better to power wash felles. Not saying you didnt do a good job just stating the facts of the process because I use to do it for a living.
thanks KB, I appreciate the comment, mike
Mike, I’ve been watching your videos for several years. You’ve always said you can do your work without acid. You show an expert (brother) using acid and all the smart Alec’s come out of the woodwork, nitpicking in a fury. Gee whiz!
KB, no one cares what you think. The guy is cleaning stone.
Incredibly stupid move to add water to acid! BAD VIDEO
Thanks Steven, mike
Incredibly stupid to be the 100th. person to make the same comment......No one cares what you think.
🦘🦘🦘🦘 ... I found this GREAT IDEA on another site & want to share it if anyone has this same problem & how to fix it. I had a terracotta pot with a wonderful indented fancy pattern etched into it when it was made, around the top & bottom sections of the sides of the pot. It had been well painted with thick black paint then sprayed over with a tough shiny, hard, silver paint over the black, but ONLY on one side of the pot!! I wanted to strip the paint to return it to pure terracotta again & fully preserve the pattern. ................ I read that full strength 🌿🦘EUCALYPTUS OIL🦘🌿 dissolves paint. I found a 50ml bottle in my cupboard & used an old toothbrush to brush in & massage into the paint: small amounts of pure Euc oil. I let it work into the paint, scrubbing it in. Soon the top silver layer dissolved away so I dripped on more oil & used old tooth brush to scrub into the black paint within the intricate etched pattern. Soon the black paint turned to tar like substance as it softened & mixed with Euc oil. I used a small wire brush & a few squirts of WD40 to scrub away the softened tar like thick black paint. WD40 will not work by itself on paint, only use to remove the tar like paint after Euc oil works. It does not take a lot of Euc Oil, use sparingly drop by drop. Clean brushes of build up if needed, with turpentine or WD40 & rub with old rag. Worked well. Used an angle grinder scrub pad on large smooth portion of pot. Wiped it with a good smear of Euc oil & left to soften, then used angle grinder with pad & it came off in one buzz. Cheers.
Thanks, Mike
