Klean Strip Green Muriatic Acid-Eco friendly Brightens Masonry Etch Concrete Removes Excess Mortar from Bricks and Cleans Algae and Scum-1 Gallon Plus Centaurus AZ Chemical Resistant Gloves

Works great for oil stained driveway.

This stuff is great for cleaning concrete and removing grout haze.

This stuff is a strong acid. Do not treat this stuff trivially. Thank the Good Lord God above, and his Holy Son and Spirit, that my wife who is an actual scientist that worked with stuff like this was on hand after I let this get out of control. I even cut it with some water and it started going crazy on some aluminum! My wife thankfully had baking soda to neutralize the reaction; this stuff was legit boiling in the glass container.Moral of the story; don't wing it in your shed. Take it outside; keep baking soda on hand, and cut the acid with more water than I did. That part was ruined boys, but I didn't get chemical burns, and the fumes I luckily didn't burn my aveoli. Don't play about with this stuff. It works; it's strong, have great respect for it.

I used this to clean a large rock in our water feature. It worked very well in cleaning the scale and brought back the color of the rock.

Klean Strip Green Muriatic Acid is a good eco-friendly option for tough stains on various surfaces. While effective, protective gear should be used when handling, and a well-ventilated area is recommended. Overall, it's a solid 4-star product

I poured this onto some oil stains undiluted. Let it sit for at least 5 minutes but then had to still scrub the oil stain out of the driveway. this will work - but it make take a couple of tries.

This product is for you if you have been dealing with stubborn hard water stains! I have hard water and no matter how many times I scrubbed my toilet it wouldn’t come out. I ordered this product as a last ditch effort to clean lime deposits out of my toilet. I was fully prepared to replace my toilet if this didn’t work. Let me tell you, this acid is a miracle worker!! I let it sit in the toilet for 5 minutes and the stains brushed away with no issues!Be aware that this is a powerful product! Because you’re working with acid be sure to wear protective gloves , safety goggles and a mask! Never poor acid into a container first then add water to dilute! This can cause a severe chemical reaction resulting in injury. Start with water first then add the acid second. Because acid is so Corrosive, it can eat through your plumbing pipes. It is extremely important to neutralize the acid with at least 16 ounces of baking soda before flushing down the pipes. Do not use this product regularly as again, it can be damaging.

Arrived intact and since purchasing. I have learned so many additional purposes for this item.
