I know this has probably been gone over a hundred times but how about a hundred and one? I have picked up several Disston saws lately at yard sales. I'll post pictures soon so you all can help me identify what I have. I can't even distinguish between a rip saw and a cross cut saw. Anyway my first questions are on cleaning these old things up. I picked up only saws that had straight blades and no broken handles and I want to keep them as users so I don't need them sparkling. Cleaning up the handles is no problem and Brasso works amazing on the brass but how do you clean the rust off those blades? I'm hoping to use something I can find locally. What are people using?
