You guys ever use this product called evaporust? You can buy it at Harbor Freight. It's a little pricey but does a real good job. I have a set of USA made Craftsman ratchets and sockets that have been abused and in storage for a long time before we bought our house. A lot of it was really rusty, so I bought this stuff to try and clean it up. No before pics of the sockets, but here's a beat down, old rusty hammer that I left sit in it overnight last night. I'm really impressed with this stuff. Label says it's safe for the environment too. Bonus!
