Concrete & Masonry Dissolver - Remover for Cement, Splatter, Concrete, Grout, Brick, Mortar, & More, Ideal for Tools & Walls (28 Ounces)

Had to remove 2 year old concrete from iron railing and this worked like a charm. This was not a few simple streaks, these were dried on drips over a foot long and in some spots 1/4” thick. I wrapped paper towels around the uprights and soaked them with the solution, let them sit for about 30 minutes, and went to town on them. Because I had to paint the rails anyway I took the them with a scraper, in some spots in just wiped off, in others I had to go at it with the tool, it honestly worked great! Be warned do not wet the concrete first, be prepared to put some work into thicker spots, and put drops clothes down because it will start to eat the existing concrete. This solution definitely weakens the thicker spots where just a few taps with the scraper got the big chunks off. I will be buying this again 100%.

It really works. I had a driveway replaced 4 years ago and the workers got little concrete splatters all over the garage door. It didn't bother me much honestly. They offered to take 10% off the price since they couldnt get it off and had to go to the next job that day. 4 years later, I've tried vinegar, pressure washer, nothing worked. Finally, a contractor friend came by one day for a party and he told me to look up this stuff. I ordered off here, and got it in a few days. Sprayed it on and let it sit for 30min, then sprayed a bit more on and scrubbed with a tire brush. All of the concrete remnants completely came off my painted garage door without any residue whatsoever after I sprayed it with a hose. The only negative is that it kinda made my concrete white! Kind of like it oxidized the solution dripped onto the concrete. I was able to use a brush and pressure washer to clean it off, but just be aware that this may cause your concrete to become chalky.

My hardened concrete was 14 years old and stuck fast to an aluminum door sill. at first the solution had little effect. Then I made a paste with this solution and baking flower. I left the paste on the solidified concrete overnight and it began to loosen. I repeated the process several times, now it's clean.

Definitivamente Este producto me desepcionó nunca sacó El cemento aún siguiendo las instrucciones

Did good cleaning up my levels for most part it didn’t do the best on medal surfaces but did tell him remove decent amount, works really good on plastic and rubber all my handles are spotless, did take half the bottle to get good results though. Still trust it better than acid on my tools

Idk what everyone else was saying this stuff worked great. I’m a detailer and needed something that was car paint safe but could remove concrete on a truck. I found this stuff and it dissolved it in like 5 mins. The customer loved the finished product. It does leave behind etching like hard water marks but I was already expecting that. I machine polished (you can hand polish to) and removed all the left over residue. I applied at 6am before the sun came out and sprayed in on the trim, glass, paint, and wheels. Worked great!

Loved this product. It worked quickly but did not damage my auto finish. I used a plastic scraper to get the concrete off. It was finished in about ten minutes. Took longer to set up the task. Very happy to have found this product.

I got the product timely Manor. It was a few days before I use it, but I sprayed it all a few of the tools that had concrete on it and it done very good job of dissolving it and so I could clean the tool.
