I have several tools (jointer, bandsaw etc.) whose table surfaces
(mostly cast iron) have become rusted due to storage in moist
environments for a time. Any recommendations for:

a) How best to remove the rust (maybe steel wool?)
b) What to put on the cleaned surface to prevent
this from happening again. Wax? oil? I'd like to
minimize the contamination of my wood when
I use the tools.

Thanks
