My table saw recently started to develop rust on cast iron top. What's
the best way to remove the rust and what should I use on the table saw
top to prevent rust?

I started to develop some rust on my TS when I hurriedly left it without
cleaning the sawdust off the cast iron top during a fairly damp period (like
all of May in Chicago). Apparently the dust attracted moisture.
Furthermore the rust seemed to be forming in the area where most of my
lumber passed over the table. I guess in a few months I wore the paste wax
coating down to the metal.

I caught it quick, just a slight darkening on the surface that quickly came
off with 5 minutes of a WD-40 soak and some paper towels. Left a film of
WD-40 on it until I get time to re-apply the paste wax.

I think it pays to look under the tool covers every so often to check things
out. I have a jointer that only gets used at intervals of a few weeks.
