Rust Release SuperGel | The Industrial Safe Rust Remover | 1/2 Gallon Jug

Messy to work with, however, the stuff does the job..

Did not seem to work all that great, for what it is worth. I had been using Evapo-Rust on smaller tools with incredible results and hoped this product could do the trick for larger items I could not submerge, such as my grandfather's old jointer. Alas, I was mistaken... It doesn't have much open time to work with before it dries out, and even if you use it according to the instructions it does little to remove the rust. Save yourself some money and buy a 5-gallon of Evapo-Rust instead.
