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

This product works! I could see it bringing the mineral deposits to the surface and foaming up. It took multiple rounds of spraying to get the deposits to completely break down but I was fine with that. I used this product indoors on a stamped concrete floor. It has no smell or at least not a strong one and does not burn the skin. It was hard to find a product that was recommended for the indoors that I felt comfortable putting around family and pets. I am so happy with the results.

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.

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.

It has only one positive point - is not acid-based, and not toxic at all.Is it effective? No! I used it for haze removal after flagstone installation with mortar. Well, this product does not work effectively.Bottom line, nice idea, but acid-based reagents are way to go.

This was my 3rd time using Eco Etch Pro and I’ve never had an issue yet. This last time though it didn’t foam up as much as the other times, though I do believe even though it was a newly poured (45 days old) slab of concrete, I believe it was a little too dirty for just etcher. So now I’ll give it a light clean and seal it and see how it goes. This is my first ever exterior concrete slab etching all other’s were done inside in a controlled climate and this is for a metal garage with no garage door so dirt and pollen keeps pouring onto the slab. Otherwise it seems to of opened up the pores like expected.

So I recently received a pesky notice from our HOA, telling us we needed to remove efflorescence from block wall. I dreaded the task because all those other concrete etchers have harsh chemicals that make it nearly impossible to apply without feeling like your lungs are getting vaporized and skin disintegrated! This product is absolutely AMAZING! Not only is it effective, but it doesn’t burn your skin or hurt your lungs. There is a slightly intense smell to it and you still should avoid inhaling the fumes, but it is possible to apply to block walls and not come in contact with the fumes.I recommend this solution over all those harmful chemicals. It is very effective on your block walls, not on your pocket.

Appears to work ok. But had difficulty getting the coverage it claims. Have to dilute to get the coverage, then its not strong enough.

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.
