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

This stuff worked great. Some of the concrete on my dump truck had been on there for over a year. It's gone now. Takes a little elbow grease with it to get thick stuff off, but a great product

Sprayed product on metal and siding. Let sit, took off nothing. Tried again still nothing. A waste of our money we will not get back. Do not buy!

Not effective

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.

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

Received a very old package. Soften the concrete a little bit (40%)

Disappointed for the priceI applied as directed (diluted) and nothing happened. I applied the next day as full strength and it loosened the thin film of concrete over spray, but anything over 1/32" it does not affect.Ill stick to the product the old timers used.

removed a lot of cement off my bricks
