Crete Away Concrete Remover & Dissolver – Non Toxic, Biodegradable, Acid Free Cement Cleaner for Dried Grout, Mortar, Stucco & Splatter Removal on Cars, Tools, Painted Surfaces, 1 Gallon

Used to clean up cement splatter from a recently poured patio slab.The cement guy was sloppy and splashed cement onto a nearby cement walkway and parking area.Used this product diluted 4:1 and sprayed it with a typical landscape sprayer for bugs/weeds.Use sparingly until you get the hang of it.It began to react immediately upon application so be careful where you spray it.I let it sit for maybe 5 minutes and then used an electric powered Ryobi 2000psi pressure washer on the area sprayed.I did it a section at a time so the chemical didn’t sit too long before I could hit it with the pressure washer.Not only did it dissolve the splattered cement, it also took off years of oil, rust, and mold stains.I ended up doing the entire walkway and parking area because it was working so well! Lol

Did not dissolve concrete or mortar on cement tools had to work just as hard as I normally do to clean them,too expensive even if it worked had to return.

Bought this on a reco from a reddit thread. Had some sloppy work to clean up from a substandard contractor. Door, siding, garage door all got the treatment. Followed the instructions, sprayed and retreated after 15 mins. While it isn't as easy as "spray and wash away" it does work to loosen and break down bigger chunks and splatters are generally cleared following the instructions. Had to retreat a couple areas and ultimately scrape a few spots with a putty knife or chisel, but Crete Away made that possible and the effort was minimal. The four star review is from the extra effort needed, but not a knock on the product. Truly appreciate that it works to weaken if not fully treat problem areas. Would definitely buy again.

Did its job

I gave a try . But it didn't work. I spray my rims , waited for fifteen min. Rinse it out with high water pressure. And it didn't remove the concrete.

We had concrete slung down the side of a pickup. It was mostly very thin but well-adhered. This product worked, kinda. It wasn't as easy as 'spray it on and power wash it off'. It took several applications, each sitting for around an hour or so, and a 4k PSI 240-degree hot water pressure washer. Eventually, we got it off using muriatic acid between applications of this product. I'm not saying it's a bad product. I realize there might be differences in the concrete it's tasked with removing. All I'm saying is if it happens again, I'll probably try one of the other products on the market.

Useless.

removed a lot of cement off my bricks
