How to remove pitting from table saw top?

Well, looks like they answered my question for me. Note to self, read the FAQ first next time…

I sprayed Rust Free™ on my Table Saw and after I wiped it off the surface has darker blotches?
What probably happened is the Rust Free™ was left on a little too long and began to form an iron phosphate coating where the rust used to be. The way to clean it up is to spray Boeshield T-9 on as a cutting lubricant, then go over the surface with a Scotch-Brite pad on a random orbit sander. That should make it look like new, and the residual T-9 will prevent further rusting.

Respray your rust remover ands hit it with steel wool for starters. The discolorations are no big deal, as long as the top is flat, and does not leave marks on your projects. If it is that bad, you might be looking at having it milled, but my gut tells me you can clean it to be quite usable with over the counter rust remover and steel wool, followed by a wet or dry sanding up to about 600 grit. After that, some paste wax should keep it nice and fresh.

I’ve always had good luck removing rust and glue from my table saw,jointer and planner by using a scotch brite pad and some automotive rubbing compound with a random orbital sander on top of the pad going over it more than once in really bad spots and then using a ROS on a soft cloth to first clean of the excess compound and then to apply wax to the surface.
