Quoted from pinballbrian:
No alcohol.will strip paint.get fine toothbrush.make sure it is fine bristle.make sure everything is removed from playfield.then get liquid lysol and dawn dish liquid.a little (color safe bleach.just a drop mixed with water).if real dirty around kickers ect.after that then use novus and mothers carnuba wax mixture.never use alcohol or anything petroleum products.check label of wax.
Alcohol will not strip paint.
Mother's will have petroleum distillates in it to soften the carnauba so that blows that part out of the water too.
You can lose paint with alcohol if you use ME with it but it's the ME not the alcohol.
Why would you use Lysol and dish detergent on a playfield?
Good Lord...
To the OP. ME and alcohol are ok but go easy. That's ancient paint on there. Easy with the Novus. Do not use any water based product. Go easy and slow .
