I recently bought a used Ridgid TS3650 for a very good deal. The saw was basically brand new with very little use but since the saw was used more for collecting clutter then cutting wood the top does have some marks and light surface rust. I am wondering if I can clean the top up with some steel wool without damaging anything? I remember many years back in my woodworking class the instructor used to have the students coat all the cast iron tops with some type of wax. Do people still do this and is there a certain type of was to use? Thanks.
