I have an old Delta Tablesaw in my basement shop. It would develop surface rust right after using it.
I too, used Norm Abrams' technique, but, I modified it a bit.
I use 00 steel wool under my old orbital sander. Very little pressure. Let the 00 do the work. Follow up with 0000 steel wool.
Wipe the saw down with a clean, dry rag.
I use car wax. I had a bunch of Blue Coral in the garage.
Nice thick coat. Let it dry. Buff it up.
Re-do the procedure as needed to maintain surface. (Normal routine, now.)
Now, when I leave the shop, I take a section of cardboard box (that paper comes in) and place it over the top of the saw. (Large paper cartons [I'm a printer] have a moisture barrier placed into them when assembled. Sometimes, it's just wax impregnated into the cardboard.)
Last item. . . . I put a de-humidifier in my basement shop. It runs 24/7/365.
A friend of mine gave me a tub of bolwing alley wax. Never had a problem with rust and wood slides right through the blade (assuming the blade is sharp, that is)...
I had a very similar problem with a table saw and drill press in an unairconditioned shop here in southern Louisiana. I cleaned the rust off with steel wool then coated the tops with BoeShield T-9. It is a rust and corrosion prevention spray originally developed by Boeing Corp to prevent corrosion in air frames. It goes on as a liquid spray and slowly dries to a waxy surface. It's not permanent; if I use the machinery much the coating wears off and must be replaced. Link below will take you to the company site and a list of places you can get it. Hope this helps.
