I Have A Couple Of Old Tools. A Delta Table Saw And A Delta 6" Jointer. The Table On Both Are Rusty And Drag When Feeding Wood. I Have Been Agonizing On How To Properly Cure This Problem. I Suddenly Had To Get It Done Today. I Used A Circular Scotchbrite Hook & Loop Pad On My Ramdom Orbit Sander And Then Automotive Paste Wax. I May Find Out Later That I Have Ruined The Tools. But For Now They Are Slick.
