I acquired at long last an El Dorado. It’s dirty with moderate planking and ball swirls. Some paint has lifted in a few areas but not terrible. What is the best method to clean it? I have a Genie as well and used a magic eraser and isopropyl with mixed results. I have heard people using lighter fluid, naphtha, a magic eraser with simple green, CP-100, etc. What is the best way to clean the playfield without causing a lot of damage? Any advice is appreciated!
