How To Remove Any Stain From Concrete (Cómo quitar cualquier mancha del concreto)

Stained concrete? No problem. Have tried everything, including scrubbing the hell out of it. No problem. This video is not to be used by children or anyone that has no sense.

[@nobrizzle]

I would also use some sort of base afterwards like baking soda to neutralize the acid to prevent any further issues as it drains.

[@billwilliams774]

nobrizzle Thank you.

[@robert28111]

I used this stuff and it came out like new . Nice job good video.

[@Tbone.357]

Best to use a thinned down version of this. Will etch the hell out of the concrete if it's left on too long. Try 50/50 mix with water.

[@blackseptemba]

Can I use a pump sprayer with this acid 50/50 mix with water. Pump sprayer from HD

[@stevemueller4703]

Great episode! Just be yourself and keep telling your story.

[@claudiotamez89103]

Ive used this over the past 40 years without ever an issue...you don't need a lot unless your preparing for an overlay.. best and safe,,,, "little by little".

[@MrShaun_D1]

so when you rinse it out of the garaged floor onto the driveway going into the drainage...is that okay?

[@WilliamAshleyOnline]

You shouldn't use muriatic acid on concrete as it will damage the concrete. For oil stains you can try something like acetone or naptha (organic solvents) trichloroethylene. Muriatic acid is best used on acid resistant masonry such as brick.

[@conquryourfear]

I have not seen any damage to my concrete. the pool guy uses muriatic acid to clean heavily stained pools; and that's not made out of brick -- and this is where I got the idea to clean my patio deck in this video.

[@WilliamAshleyOnline]

yeah it is great for cleaning but it also eats away at concrete.

[@johnireland3521]

What would you know cock nose

[@maxberry3464]

Im a mason and the brick cleaners use muriatic acid to remove cement left from the bricklayer and to remove the slick finish on the joint to show the aggregate essentially eating the concrete. This should have been diluted so much though and brushed around. Brickcleaners use 1:20 water but no more than 1:5. Looks good

[@paulinamb]

William Ashley does this work with dog pee on concrete?

[@qwertyuiopasdfghjkl7422]

some old concrete can turn brownish so always test a spot if it is brown use an aluminum brightener to whiten the concrete

[@Homepros888]

You should have use a brush, it would have clean it better and cover a larger area. Get a brush that you can screw on to a stick ( like a push broom). The brush you get should be nylon (acid safe) or stainless steel bristle. Wear safety glasses, gloves and respirator. Here in NYC I have customers that live near the highways and they get a lot of sloot and dirt from the cars, I go clean their bricks and limestone stairs step after the acid wash it looks brand new.

[@TheMysoldier04]

What about stains inside your house? I'm assuming NO. But I'm trying to make my slab all one color or close to one color before we seal it. What do you recommend?

[@hobiebassassassin9136]

You should try acetone on a small section of concrete and go from there

[@grapefruits_gd-geometrydas5604]

Does it taste good?

[@conquryourfear]

too much fizzzz for me

[@MrTopsyTervy]

Good idea, but definitely do not want to breathe the fumes, wear safety glasses and gloves. Having worked in the swimming pool industry for over 18 years, and doing many acid-washing of plaster pools, I've had some close calls with muriatic acid, it's some bad stuff, and frankly there are better materials to use to clean concrete imo! The muriatic acid will also eat up the mortar in the concrete leaving it very porous if you leave it on too long. Before rinsing, I would suggest neutralizing the acid with soda ash or baking soda. Everything can be purchased(as well as further advice, tips) at your local mom & pop swimming pool supply store. Be safe out there! -Trent

[@paulinamb]

K. Murray would these work with dog urine on concrete?

[@KM-xn5kj]

Paulina Medellin it should... If you agitate it good enough and let it sit ..they have different types of choices for different surfaces..if you acid you have to be VERY careful with it..don’t breathe in the fumes and wear proper PPE

[@KM-xn5kj]

Paulina Medellin I would recommend you check out pet stores too..they should already have particular chemicals to use for pets ..if not check out lowes or home depot

[@LamborghiniGal]

Thank you for sharing. I LOVE the statue, by the way. :-)

[@eknight101]

Bro, that Muriatic Acid is absolutely lethal. I'm surprised that retail stores are even allowed to sale it to the average consumer. I used Muriatic once on a 30 year old pressure washed driveway with really stubborn stains. I diluted it, which is probably the reason that it wasn't effective. Either way, I will never use that stuff again for anything. Even with full PPE on, it's still too dangerous to handle. Even a microscopic spill will burn the heck out of your skin and eat through your clothes. I'm going to look into using phosphoric acid for any future jobs. I'm told that it's a lot safer and just as effective.

[@TheSargeGaming]

Thank you for sharing

[@extremesteamcarpet]

So you put it out straight ? No dilution ?

[@conquryourfear]

Yes sir

[@shywiz1543]

I live in an upstairs apartment and our balcony is filthy with stains everywhere. Our porch is shorter than the downstairs so anything spilled falls onto the neighbors balcony. Are there any tips for cleaning my balcony without getting stuff on my neighbors? Thanks.

[@conquryourfear]

You could get some used old towels and put them on the edge of the porch to prevent over spillage

[@truvipbabee]

Nice thank you

[@hanskonrad5850]

correct nobrizzle thankyou

[@dennis17116]

[@fatwanmunaser2516]

Let people know that you need to wear a mask to not breath the fumes. Very dangerous to breath the fumes.

[@conquryourfear]

fatwan munaser definitely good advice. Thank you brother.

[@aeroblivion2823]

Well if you’ve actually ever been around the stuff it’s almost impossible to breathe so...

[@NdnUrbanCat]

Eye goggles wouldn't hurt, either.

[@Brutis-tj9qn]

@@aeroblivion2823 Muriatic acid is literally a gas , how would you not breath it? You should be using an respirator with acid gas filters to be safe. Used directly like he did on this video , it literally emits a thick yellow smoke....

What do you recommend for the stains that the smoke ball leave

[@danieldelatorre1673]

I had a fire pit on a concrete patio and some chunks of burning wood fell and left black burns. Will it work on that?

[@peterhenry2923]

You should be rinsing this off with baking soda and water mix. Acid will continue to eat away at you concrete otherwise. Basic chemistry you silly boys.

[@conquryourfear]

this video was done back in 2015. no such "continu[ing] away".

[@RenataGruszecka]

absolutely right

[@restlessflame]

Where did you buy? How much does it cost? My garage floor DESPERATELY needs that. Wondering how many gallons I would need. I finally bought a 75 foot hose :)

[@maryleebrooks4829]

danae what did you use

[@restlessflame]

Never done. Sigh.

[@Brutis-tj9qn]

Muriatic acid will rust anything metal in your garage, as it's really a gas not a liquid. ( the gas is what destroys metals). Use phosphoric acid , much safer and will do the job. Buy the concentrate it's about $20 for a gallon , dont buy the premixed stuff ( products containing phosphoric acid) As they are a waste of time and money.

[@callieannabrown2258]

Would this work for stains from smoking ? Also if the patio is on the second floor of apartment building would this chemical not be a good idea due to the downstairs peoples patio/plants

[@conquryourfear]

I would surely take care of those smoking stains. You have however a dilemma regarding the neighbors downstairs. Therefore I would suggest that you find an alternative. Sorry.

I just need to clean my concrete patio of the green algae, moss and mildew that grows on it due to living in a hot, humid state. Will Muriatic Acid do this? How long do I leave it on my concrete? And do I need deactivate it with baking soda before rinsing so as to not kill any plants and grass around my patio? Thanks for any advice!

[@conquryourfear]

Nightbird I'm not a professional. I am just passing my experience and results on. It was my experience that after leaving that acid on my concrete, it cleaned itself after about leaving it on the concrete for two minutes. After watering it down, and watering the edge of my grass, my grass was not effected.

[@markm2302]

Use diluted bleach for mold, NOT acid.

[@gatecrasherkz7]

Nightbird, I seal concrete for a living. I would use a 3000psi (min) water blaster which would remove all moss. I use a whirl a way attachment on flat concrete. If you wanted to seal it I would then use hydrochloric acid to acid wash the area (1 part acid to 9 parts water). First, wet the concrete with a hose then apply the acid with a watering can and be careful not to miss any areas. You can use a broom If easier for you to get 100% coverage. Leave for at least 30 seconds for the fizzing to stop then hose off with water. Work in stages. Let concrete fully dry. Apply sealer the next day preferably if no rain is forecast. Sealer can not get wet until it is fully dry

[@dingo3354]

@@gatecrasherkz7 and the difference between muriatic and hydrochloric acid would be?

[@gatecrasherkz7]

@@dingo3354 it's the same, but where I'm from (NZ) no one uses the word 'muriatic' 🤷🏻

[@KingParisBuckingham]

Yes this acid is the best but depending on how bad stain is you have to know just how strong to makenit,cause dont want it rating up the concrete too bad ( i use it for like half hr soaking wash off then use clorox water to whiten,then wash off

[@doola1609]

Is that like hydrochloric acid?

[@conquryourfear]

nope

[@conquryourfear]

straight up hydrochloric is stronger. this stuff is a mixture of it.

[@doola1609]

I've worked with hydrochloric and hydrofluoric acid. Both very nasty..

[@Zourkoskey]

Muriatic acid is hydrochloric acid 30%

[@SmurfYeahBizNitches]

What is the environmental impact of using this? I have a few stains in my garage I need to take care of but if this stuff changes the PH balance of my yard my avocado trees are toast. No pun intended

[@conquryourfear]

I have had no visible differences to report after this video was taken. I did thoroughly rise the concrete and grass adjoining the concrete.

[@BracaPhoto]

Add baking soda or ammonia to the acid BEFORE you rinse it away and it will neutralize the acid... If you're really worried about pH levels use some pH paper to check it BEFORE you wash it away

[@TruthSurge]

jesus..... no one pays attention in school? It's just an ACIDIC compound. If you dilute it with water as he did when he rinsed it, it will be less and less acidic because it is more and more DILUTED. There is no environmental impact if you dilute it well once it's done its job. What's the impact of pouring out a Coke into the grass? That stuff has phosphoric acid in it. It'll eat a hole in your stomach if you drink it all day.

Zero damage. I watered down the grass a little. But seriously-zero negative affect.

[@demon__adrian393]

what do you do if its in a basement?

[@conquryourfear]

there's this other stuff that's much safer. Called, Simple Green. it's no where near as toxic as this stuff. the trick is, don't be shy in applying Simple Green on the floor, put enough for the floor to soaked. let it sit for 3 minutes. then grab scrubber (or a broom) and scrub away without worrying about the fumes. Rise. if you have windows, open them up. and if you have a fan, face it going out on the threshold of the basement door.

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.

You are right that it is not special and its basically $4-6 for a gallon, but it is not the same as Hydrochloric acid. I think if you add salt, you can consider it "hydrochloric" acid, as its missing that part :-)
