My table saw has been living unused in a garage for two years and developed several small rust spots and stains that I would like to remove now that I'm in a position to use it. I read in a local woodworking forum of a guy using a random orbit sander and 180 grit paper to remove all the stains on his saw. My question here is is that a reasonable approach to remove the stains. I've used WD-40 and 4 ought steel wool to remove the rust but the stains remain.
