EcoProCoteEco Etch Pro Concrete Etcher, Concrete Cleaner, Efflorescence Remover, No Fumes, Will Not Burn Skin, Safer Than Muriatic Acid, Stronger Than Phosphoric Acid, Will Not Harm Plants, 1 Gallon

I have a colored concrete driveway that was poured just a week ahead of the cold winter temperatures setting in. Unfortunately, the efflorescence that formed created a terrible, splotchy appearance which almost completely negated the colored look which is what we paid extra to get. I tried a variety of products, some acids, some other efflorescence removers, etc. but this one was worth the money spent. It works exactly as the manufacturer claims. It foams like crazy when poured onto the surface of untreated concrete and definitely etches it. The one thing that it is not effective at doing is treating efflorescence that is covered with a sealer. The label clearly states this however. I have learned that I first have to take steps to remove the sealer that remains on the driveway and then use this product. Once that is done, the results are very good. I highly recommend this product.

Bought this for all the calcium build up on my bathroom tile grouts.Works like a charm. My dark brown grouting had gone white with mineralization. This got rid of it, all of it.

Product does not burn skin as it says but did bother my throat but went away after use. I suppose that should be expected with any cleaner that will work. It cleans well if you do not dilute it as it states. If you cut the recommended dilution in half it works well with hard scrubbing and some elbow grease. Decent product if you don’t want harmful chemicals.

I love this product. I had to etch a concrete garage floor to prepare to stain. This product is very easy to use if you follow the directions. It also gives a deep cleaning to the floor. This is completely non-toxic. No fumes or bad smell. Cleans up easy. I watered down after use and used a shop-vac to clean up the water. It gave me the pourous surface on the concrete I was looking for in preparation of applying the stain. It is definitely Eco friendly.

The first gallon did just what it should do but the second left more white residue than what was on the brick to begin with. Now I just have a mess and am going to have to pay someone to come look at it and see why some bricks have more efflorescence than they did and why some grout came clean and some didn’t. I had someone helping me from the company, but he left for the weekend and I didn’t hear back on Mon, Tues or Wed. Of course it can’t be returned so I’m just out the money now.
