Where the mylar is not, what should I clean/protect playfield with? For instance on my Rollergames on the upper playfield where the lane guides are and around the pop bumpers it looks like it is just graphic with no mylar protection and other areas like the ball drains and chutes. Currently have my Rollergames tore apart and would like to wax before I put it all back together. Any other advice while I have a lot of it tore apart would be great also. I currently have on hand some Honda Glare Professional Polish and Honda Spray Cleaner and polish. I am looking into Wizards Mist N Shine and Maguiars carnuba wax.

Never heard of Naphta? Should I put mylar in the chutes on There is already some wear where the ball travels.

Naphtha sounds pretty harsh to me. Pinballlife.com has some mylar that I ordered. They seem to have the best prices.

I think if you use magic eraser lightly it will not harm, but apply light pressure when using.
