My clear plastics have turned a light shade of brown/tan/yellow. I'm assuming this is what happens to clear plastic after almost 30 years. Is this cleanable? I'm not going to attempt the flame-treatment method because lord knows I'll f*ck something up that I can't repair. It doesn't really look like they can be cleaned, but I thought I'd throw out a quick call for help.

Thanks everybody!

Might be. Maybe that new as seen on tv stuff for dim headlights might work? Anybody tried that?

Thanks everybody. It's not really a huge issue. I've got the whole play field disassembled so I'm just trying to hit every red flag before I put it back together. Looks like she'll just be a little yellow in some spots.
