Quoted from Otaku:It's funny, I bet the pinball community outbuys the majority of Novus for use on wood compared to people actually looking to use it to clean plastic containers like it is intended to be used. Anyways, the proof is in the pudding - lots of satisfied pinballers 'round these parts use Novus to clean their wooden playfields.
No one here is using it on wood. We're using it on lacquer or polyurethane, aka plastic. The fact that there's wood underneath is incidental. Try some Novus 2 on the bare wood bottom of your playfield. I don't think you'll like the results.
