Quoted from adamtoth:... remove mylar with the compressed air/freeze spray approach. I'm having trouble finding a brand that doesn't have a bitterant added. Or can it negatively affect the playfield surface?
I have removed a lot of mylar off playfields over the years. I have used real freeze spray, compressed air (upside down) and stuff with bitterant and without it. Bitterant does not affect the playfield. Most compressed air cans have bitterant to help stop kids from huffing it. I would just use the stuff that you can easily find.
