I'm assuming you have a cast iron table surface. Spray the surface
liberally with WD-40 and let it sit for a few minutes, longer if the rust is
particularly bad. Take a green scotch-brite pad and either by hand or on a
hook-and-loop orbital sander rub the surface to remove the rust and polish
the top. I've done this several times and never had a problem getting light
oxidation off of my tools.
After that, I use a product called TopCote by Bostik

This seals and lubricates the surface very well.
There are no stupid questions.
There are a LOT of inquisitive idiots.
