- kragen 3y agoyou can use paraffin wax, beeswax, carnauba wax, or linseed oil (ideally without heavy-metal catalysts) there are probably a lot of other alternatives that i'm not thinking of fluorocarbons work better, are less toxic, and consume less resources because you can use less of them, but they aren't essential
