Review on Singerman Labs Concrete Rust Remover - Convert 22 oz into 1 Gallon by Carmen Peterson

After receiving a ridiculous offer from my mechanic, I decided it was my duty to clean my dirty battery terminals. After weeks of hesitation and an occasional bout of shared ambition, I set to work on the blue-and-white sour cakes with a toothbrush, some baking soda, and water — only to find multicolored bubbles of toxic grime dripping and running down the driveway. . I confidently assured my girlfriend that the battery acid will wash out immediately and I know what I'm doing. Boy was I wrong! I made an unsightly mess out of concrete and my girlfriend reminded me that not only am I an idiot, but our driveway will always look like these weird photos of the surface of Mars (rather than in a cool style like Carl Sagan Cosmos) . I googled the best concrete cleaning methods and tried pretty much every single one of them. After over an hour of washing, spraying, soaking and sweating in the sun, the "before" photo is the best I could get. I decided to purchase this magic powder on a whim, very unsure if anything else could be done. It says to wait 5 to 15 minutes, but before I finished applying, the spots before my eyes were gone. Truly unbelievable! I am forever indebted to Professor Singerman and his team of chemical crackers for cleaning my porch, saving my relationships, and restoring my confidence in consumer goods. In the meantime, please accept my $40 and a heartfelt thank you! TLDR: My girlfriend is smart and I'm not, and the $**† WORKS!
