Eco Etch Pro Concrete Cleaner & Etcher Dissolver - Efflorescence, Rust & Dirt Remover from Brick, Driveway, Garage - Gentle Substitute for Citric Acid - Non-Toxic & Safe - 5 Gallon

Non abrasive cleaner. Removes concerted, mortar splatter. Really good on glass for removing water residue easily. Strong acid odor use proper hand protection. Indoors use in well ventilated areas. A favorite cleaner for construction Why did you pick this product vs others?:ECO

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 product worked wonders cleaning my exterior basement walls. I would highly recommend!!!

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.

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.

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 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.
