Concrete Dissolver

I bought this in a desperate attempt to clean off over-worked grout. Foolishly I grouted late at night (base tile) and didn't bother cleaning it off. Big mistake. I was left with smeared dried grout on my tile that would not budge. There were other projects that needed to be done, and I wanted to finish the rest of the tile - so I just left the base tile as is for several weeks, figuring I would get to it when I get to it. I discovered that cleaning off dried grout is nearly impossible. I tried an acid based cleaner that did very little, and even the "sugar water" trick. Surprisingly that did help a bit, but was too much scrubbing work. THIS product worked like a charm! I can't believe how well it works. I wish I had before and after photos to post. Spray it on, leave it for 20 minutes, then use a scotch brite pad. I also had to use a plastic scraper in certain heavy areas, but now my tile is clean! The really bad areas like the corners needed two applications, but it worked. I don't know how this will perform for other issues, but for dried grout - this is the one!

Right next to where I work and park, there was construction on a new apartment/condo building. A whole lot of mortar ended up on my car without any warning. No sympathy from the construction company. This product got it off well after it hard hardened (took an afternoon and a few applications), but this product runs and left streaks in the paint. It works, but be prepared for your car to not look the same. Mine is silver, for reference - it lightened the color.

My 'low priced' concrete guy left me a mess. Concrete splatter on nearly everything (walls, doors, etc). Scraping alone will only damage surfaces. I hoped to find an easy and effective chemical solution but not an acid. Speedy Clean did the job. It sprays on foamy and needs to sit on the hardened concrete for a full 10 minutes. I then used a 4 inch scraper to easily remove the splatter. Anything that didn't want to easily come off (super thick concrete blob) received a second treatment. It all came off with no damage to underlying surfaces. Be sure to wash the area well to neutralize the cleaner and lay down a tarp before starting if working on a concrete floor so you don't damage the floor.

Product took 90 year old concrete off a waste pipe under my basement slab. Now I can tee off the waste pipe and install a bathroom in basement. After applying product to concrete covered cast iron waste pipe I waited 20 minutes then uses the nail-remover side of a hammer to scrap off concrete. This required a lot of scrapping and three applications. However it worked great. Thank You. Save me a ton of money, plumber wanted to replace the whole pipe under slab. Picture 1 shows pipe, picture 2 shows pipe with this product spayed on and picture 3 shows finished product. I am so happy.

I used it to remove cement from the front of my fifth-wheel trailer. I had not realized that the splatters on my trailer were from wet cement. I had tried scraping, vinegar, WD-40, alcohol, Simple-Green, etc. and nothing would take it off. Then, 6-months later it dawned on me that the splatters might be cement. So, I tried Speedy Clean Concrete Dissolver. It took several applications, but the cement softened so that the majority could be wiped of and the rest could be scraped off with a plastic scraper. It did not damage the surface of the RV nor the vinyl trim that runs around the perimeter of the front. I highly recommend it for cement removal.

Product does work! However it takes 5 or 6 applications if the thing your trying to remove the concrete from is not laying flat as the spray just runs down. We removed splatter from vinyl siding, vinyl railing, metal garage door panel and the bottom of metal gutter drain

does not work as advertised. it will help in softening the top of the ceramic tile mortar/grout, but will not fully dissolve mortar even after repeated sprayings. I ended up using a 4.5 inch double row grinding disc on my grinder to remove the mortar for the 12 tiles that i was replacing. used the remaining spray to keep dust down when using the grinder to remove the mortar.

Some dummy (that would be me) stuck her left hand in a bucket of wet grout while wearing a diamond ring guard. Grout stuck to the back of the 1/4 carat diamonds, of course. I tried all kinds of things, but I finally gave up and ordered this stuff. Soaked for 5-10 minutes, picked up with tweezers out of the solution and rinsed. After two repetitions and a little scrubbing, took 99% of the grout off. At least I didn't have to go have the stones removed. The label does have a bunch of different warnings about how bad this stuff is for you, so be careful with it.
