Hi everyone, I recently picked up a Gottlieb Slick Chick (1963). From what I heard from the previous owner, the machine was left with the glass off for a long period of time and got very dirty (may have been left in a shed). Attached is an image of the playfield currently which I think looks pretty bad.
So I was wondering what would be the best way to go about cleaning it. I was reading in some other posts that I could use vp&m naphtha, novus 1/2, or alcohol+magic eraser. I was reading that vp&m naphtha was safest to use but I can't find any in Canada that doesn't have some sort of additives. I read in other posts that the other methods could remove the paint potentially. So I was wondering if there was either another method to cleaning it that I haven't mentioned or if one of the other methods (Novus or alcohol+magic eraser) potential for paint removal was exagerated/unlikely?
Also, for whatever method you recommend, what would be the best method to apply it to the playfield? Thanks!
