Bear with me, I know there's a lot of info out there and I HAVE done a lot of reading. I tend to over-research stuff and of course, if you read enough you can find both people saying one method is great and an equal number of people saying DON'T ever use THAT method..... Case in point, when I was working on my Comet I sourced naptha, (not easy in California), and it made NO difference in cleaning my playfield. I simply used naptha on a rag. My Comet had quite a bit of planking but no horrible, worn to bare wood damage.
I understand that different playfields from different manufacturers and different eras play into cleaning technic as well. I am now wanting to clean a Stern Meteor playfield. It looks very dirty but I didn't see any planking on initial inspection and no, "worn to bare wood" spots. So after having done more reading I think I want to try magic eraser and 91% alchohol. I understand I need to not be aggressive and from what I've read I'll need to clear coat afterword. My questions are:
1. If I go this route should I move in a back and forth or circular motion, or does it matter?
2. Can I get away with a rattle can clear when I'm done? I plan to take everything off the top side of the playfield.I'm not a professional painter!
3. Do you have any specific advise to cleaning and preserving a 1979 Stern playfield?
4. If you DO have a recommended method given the make and age of my playfield could you recommend any better technics?
I know it's hard to give advise without seeing what I'm working on but I can get to the machine this weekend and take some close ups and add them here.
Thanks in advance, Bub
