Quoted from scampcamp:When you install a playfield protector... is it best to remove the wax from playfield 1st?
We do. We clean the playfield with Naptha first. We also use the Naptha to clean the bottom of the playfield protector as well before we put it on the playfield. Let the Naptha completely evaporate and make sure there is none left before you install the playfield protector.
If you do not clean the surfaces properly, wax, gum, glue etc, etc can make the protector stick to the playfield.
Good Luck!
