Rated 3.3 out of 5 by 9 reviewers.
Rated 1.0 out of 5.0 by Glorified general cleaner I bought this primarily to clean Efflorescence from my basement walls. I tried it at the recommended usage per instructions. It didn't work. I tried a 3 to 1 ratio and it still didn't work. I scrubbed the walls with a stiff brush during the applications. It cleans dirt but this turned out to be an expensive cleaner for nothing. "DO NOT BUY FOR" Efflorescence. December 8, 2015
Rated 1.0 out of 5.0 by Barely worked I have a concrete driveway which is ten years old. Last winter while I was gone my son used fertilizer to melt Ice and it left rust stains on the concrete. I tried CLR which did not work at all. so I ordered this product and applied it exactly as stated in the instructions. I worked small sections at a time and could see it was not really working even after 30 minutes. I decided to leave it on longer and ended up with it on for about 3 hours. I never let it dry. finally I rinsed the stuff off and added a neutralizer. When the drive dried out it had a whitish color wher the concrete was bare(no rust) The rust spots were still there. wife says the product lightened up the stains a little. The reality is the product did not work as expected. I expected an expensive product like this to work but it did not. April 21, 2015
Rated 2.0 out of 5.0 by Not much phosphoric acid I bought this to use as phosphoric acid, and explored the web site, the MSDS, and even the bottle after I got it for a list of ingredients. No specifics given, except that it contains phosphoric acid. After I open it I tested it for the amount of acid present (I am a chemist and university professor) - it is only about 25% concentrated phosphoric acid. It is green (not clear like pure phosphoric) and is foamy like it contains some detergent. It would be good if the manufacturer included a list of ingredients, or at least a statement that it is ~25% phosphoric along with detergent and inert ingredients (water?). It is useless for my purposes, although I imagine it would work for the cement & tile cleaning for which it is marketed. Please label the product! May 7, 2013
Rated 5.0 out of 5.0 by Best concrete etcher/cleaner available Why don't they stock it? It has been around for decades and is harmless as they put it in cola soft drinks. Put it on concrete, scrub it and wipe/hose it off. Bingo, brand spanking new concrete ready for painting or leaving as is. December 10, 2013
Rated 5.0 out of 5.0 by Product has many uses Bought product mainly to clean/neutralize rusted auto parts. Seems to work great fot that. I removed all scale rust and applied a 3:1 (3 parts water > 1 part phosphoric acid). The rust started dissolve and I eventually was left with a white zinc residue. I also used it to clean up some lime deposits on my masonary chimmney. So far this product works great for a variety of jobs. Nice to have on the shelf. September 6, 2011
Rated 5.0 out of 5.0 by It does a great job of cleaning my tile. I used this product on my kitchen floor that seems to get dirty with grease and kitchen messes. The tile has small holes in it and they seem to catch the mess. The acid loosens it and makes it easy to clean with a stiff brush. I use a floor cleaner machine to pick up the excess water after diluting the acid that was applied to the floor. December 11, 2012
Rated 5.0 out of 5.0 by Cleans bluing finishes right off Seems to get my job done pretty well. A lot easier then sanding. May 21, 2013
Rated 5.0 out of 5.0 by Worked on tough concrete stains Worked as well as muratic acid on cleaning and etching concrete but much easier to work with. (less caustic) March 20, 2012
