You can use any type of wax as long as it does not contain silicone. Most car waxes contain silicone. Silicone will interfere with some finishes and stains if it transfers to the wood. Most people use Johnson's paste wax. I use Minwax finishing wax because that is what I have on hand. There are folks who use silicone to lube their table, but they are just playing with fire!
