Eco Etch Pro Concrete Cleaner & Etcher Dissolver - Efflorescence, Rust & Dirt Remover from Brick, Driveway, Garage - Gentle Substitute for Citric & Muriatic Acid - Non-Toxic & Safe - 1 Gallon

Product worked great, in conjunction with the hard plastic bristle brushes that I purchased for my drill, at removing the efflorescence from our red brick house.

The product did a pretty good job I did 2 applications and the areas where the efforvesents was minimal came our perfect. The areas where it was very thick will need a 3rd or 4th application. I bet muratic acid would have worked better but I’m worried about getting it my eyes or skin. I will try this 2 more times.

This worked so well for my outdoor pavers and efflorescence. Had a bunch of white stains after a huge rain.Sprayed this with a $20 pump. Scrubbed with a brush. Gone in 5 min.

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.

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.

Does not do anything at all.

This works but I had to treat the areas several times to get rid of it all. If you follow directions and scrub hard with a hard bristle brush it does the trick. It can take 15 minutes or more and some heavy scrubbing labor. I got a brush that would screw into the pole on my push broom for easier scrubbing. Instead of using a sprayer to apply the product I just put it into a spray bottle as I only had two spots about 6” in diameter to treat.

I followed the instructions and the white calcium buildup on my paver stones was not removed using this product. Would not recommend
