Any suggestions on removing surface rust from machined cast iron surfaces?
From time to time I salvage a machine from someone's garage or barn and clean it up. Big jig saw, jointer, and latest is a 14" band saw. Usually the table surface has light rust.
I've used steel wool, and Scotchbrite, with oil, and it seems to work OK. It's a lot of hand work though, and for some strange reason the table surface turns kind of black.
Any other suggestions for methods or materials?
