After last weeks monsoon, my jointer had a faint hint of rust on the beds. Remembering that recently I had seen a tip to use aluminum foil to remove rust, I tried it- It Worked! Just wad up the aluminum foil and use as a scrubber on the rust. Cleans as well a steel wool. After cleaning, rub the top with some waxed paper to make it SLICK. Be sure to buy your own foil and waxed paper.
