Quoted from Hayfarmer:What brand of naptha are you all using? Alcohol is impossible to find right now. Thx
I get it at Lowes or Home Depot. They have it in quarts. I would definitely recommend it over IPA on anything that has clear, paint or ink. IPA might work fine on 20 playfields in a row, but that 21st playfield might lose paint down to the wood before you know what is happening. Either way, always start a cleaning by testing the method in a hidden spot.
