After reading a couple of threads which talked about Evapo-Rust, I decided to give it a try. I had a 20% off Harbor Freight coupon, so I picked up two gallons. I had disassembled a Model A Transmission way back in the 1970s and the gears and such, which sat in a box in my basement since then, were a rusty mess. I soaked half of them over night last night. (The other half and the case are soaking now.)
Besides soaking I used a brass brush (also picked up at Harbor Freight) to scrub off the black residue that forms as the rust is removed at about the 4 hour point, and buffed away the remaining black coating today. Here is the result! I am sold. Great Stuff!
