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.

I think it did a fair job of etching and cleaning basement floor. It certainly etched well and the odor was tolerable. My wet vacuum had some concrete dust in it so it worked.Concerns: they say it has a ph <1 but isn’t harmful to skin. I wore gloves and rubber boots along with painters overalls.The active ingredient is not listed. Not a concern for me, but would be important in an accidental poisoning incident.There should be a glued on seal under the cap. There was obviously some minor leakage during transport, although not enough to really complain about.

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.

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 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.

Does not do anything at all.

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.

I used this product on my pation to get it clean and ready for a stain. I sprayed it with a spray bottle, used a stiff brush then rinsed. Patio is old so it had some spots that still had the sealer but it was mostly gone. It didn’t get rid of all the sealer patches but I think it made a good job of cleaning the surface and getting it ready for the stain. 1st picture is before, 2nd picture is after this product is applied and 3rd photo is after 2 applications of concrete stain.
