Hi all, I have been on this forum a few years now, but haven’t posted much. I finally got my second machine, and I’m working on my first real “shop out” (my first game needed a few things but was mostly looked after). I may have many questions along the way, and I will come back to this post to add new questions.
First up, there are small rubber caps the hold down the playfield plastics. They are threaded like screws. Are these okay to clean in the ultrasonic, or is I best to replace with new? They seem like they would dissolve over time, but are sturdy enough now to lightly squeeze and no cracking develops (so far). They are the originals, this game has apparently never been cleaned up since 1979. Thanks!
