Customer Reviews for Klean-Strip Green 1 gal. Green Muriatic Acid (4-Pack)

White floor was extremely dirty, dogs do a number on the entrance and simple brushing with degreaser was not cutting it anymore. I was amazed at the result.

Cleaned my porch before painting it. Worked great.

Klein-Strip was for a brick fireplace clean project i clean real good

Clean hardened calcium buildup in toilet within minutes

Cleans Old Toilets and makes them look like new

I have used muriatic acid for many years. I use the reuqired PPE and work carefully. After all, it is acid. I really appreciate the low odor feature of the Klean-Strip Green. I used it to etch a concrete garage floor. Working indoors, even with good ventilation, with conventional muriatic acid, can be a bit intense, but with Klean-Strip Green, I never noticed any objectionable vapors.

I purchased the Klein Strip.Green for the purpose to remove paint from my front concrete patio. I applied as the instruction on the label, I let set for 5min-10min after I used the a wide brush & scrapper to remove the access paint . It spotted in a few places, but didn’t remove the remaining paint. I informed the sale person for my use to remove paint.. he recommend the product .

Wear old shoes. Use protective gear. Avoid letting undiluted product continue down driveway --as that was the purpose for my use, cleaning old driveway stains. After degreaser, this product took that last layer of dirt out of the concrete with several consecutive treatments. This was mostly caution on my side as I was nervous of it etching too deeply at a given time. Apply, wait ten, rinse. Three times for light dirt, five for the heaviest spot. Before image is from beginning to degrease. Brake Cleaner and rags, then power wash with Dawn dish soap. After image is post third application of this product. Still needed some touchup in center and low end of that block of driveway to equalize. Next step is to apply some concrete patching material to smooth out pock marks (went too heavy some spots) and seal.

have aquapure that has heavy calcium deposit (6 years without cleaning). it wasn't generating any chlorine anymore and was throwing a 120 code. I then followed jandy instruction to mix the muriatic acid with water and soak the cells for 30 minutes. calcium mostly gone. I will follow up in a couple months or so to do a 2nd cleaning. The error code is gone now and seems like it's generating chlorine again!

This muriatic acid I bought to clean the inside of a rusty steel gas tank worked wonders, very happy with it, especially for the price

I used this to remove mortar haze from the steps that I repaired the day before. I didn't like having to use such a strong toxic product, but that was what the job called for and it did what it was supposed to do simply, quickly, and easily. Next time I will be more fastidious in my post cement work clean up.

Did what it was supposed to do - removed the mortar film from my new flagstone patio. I put about 28 oz and 2 gallons of water in a spray pump and scrubbed away. No fumes, easy to use and it worked!

Used this to clean ac-heater vents from 1953 and came out stunning (like New)

I wish they would use the winged seal design that lifts up so you can grab it and peel off the seal. Without the wing you have to poke through the seal or cut it with your knife and inevitably use your fingers on the wet side of the seal. It is acid so both of those methods make me a little nervous. I am able to get it done without too much trouble but some older people or those with limited dexterity may have a problem. Other than that what can I say. It's acid and yes I would buy it again. It doesn't splash easily so if you are careful you shouldn't get it on yourself.

Product does not strip galvanized metal as good as it should. Took way to many bottles

Wow!! Much cheaper than the premixed etch stuff. I just followed the directions, and it went perfectly! I just used a cheap sprayer and bought a acid brush for about 5 bucks. You have to basically spray and brush at the same time to keep it going. I dreaded this whole process, but it was actually pretty easy.

I bought it to remove green algae from my pool. The last stuff I bought was from the pool store. This stuff did not work. It must be a lower concentration or something.

Not too strong. Perfect for garage floor cleaner and prep.

Used it to clean off oxidation from electronic equipment/metal.

Excellent strength Muriatic Acid that we used for cleaning our carport floor. The first step for us was to strip the cheap paint that was applied many years ago with a decent stripper designed for that purpose. Once the paint was lifted we found a horrible concrete surface that required an acid etching/cleaning effort to remove the streaks, stains and muck on a carport floor neglected for over 20 years. We mixed the acid at a 50/50 solution [SAFETY NOTE - Place water in bucket first then add acid] and applied it for 15 minutes. To neutralize the acid we used baking soda straight from the box - the floor consumed 4 full boxes - and did a final cold water rinse using the garden hose. The floor "came back" and took on a clean concrete gray. We waited 12 hours and sealed it with a concrete sealer design for this purpose. REMEMBER- USE EYE GOGGLES, RUBBER GLOVES, RUBBER BOOTS and a MASK DESIGNED FOR THIS ACID! The photo, below, shows an area where we tested the acid to see how it would work. . . "a picture is worth a..."

My girl friends daughter 8 years old spilled paint at the entry way of her shop, alot of paint. It was water base but still left a large ugly stain. Water ,soap, other chemicals did not improve the look. Used muratic acid and a wire brush and the stain was gone

The countertop was great ,but installation leaves a lot to be desired, they damaged our cabinet and instalantio should have been a lot better, attitude of installer leaved alt to be desired.i heard they have since switched installers

I have a 1999 Miata and I hadn't been able to clean the stock alloy rims with a variety of cleaners and methods. I diluted the muriatic acid with water and (with rubber gloves and eye protection and outdoors) just wiped it on repeatedly and it started taking off the discoloration almost immediately. The picture shows a cleaned section at the bottom. This was after they had been cleaned with soap and water. I used baking soda in water to neutralize the acid and rinsed thoroughly with water.

Good product, fair price, good delivery. Thanks.

Excellent product, prompt delivery.

Worked well to clean patio tile.
