I was showing my kids my old collection of Game and Watches that I had from when I was little. Their interest in these games have sparked my interest again in the games. They are all in nice condition and I took excellent care of them over the years. However, I noticed that the screens have started to warp a little on some of them-like my Widescreen Donkey Kong Junior DJ-101. Is there a way to fix this? Also, I decided to buy a G&W from a flea market-but it is dirty and dusty. I don't want to open up the game and clean the inside-just on the outside-how do you clean the screen on the Widescreen Mario's Cement Factory without damaging the thin plastic film?

Thanks for any help on cleaning!

About the warp thing, that is normal due the age and time like sunlight, hot or cold.

The best way is remove, put some heavy books above and after a few days he backs to the original form = plane.

For clean the glass screen just use cotton and glass cleaner for example, in the end clean with soft paper (like kitchen paper).

The exterior plastic you can clean with water and liquid soap just pay attention to the speaker.

Thank you for your response!

The polarizer film on my Snoopy Tennis was bulging out ever since I got it, was distracting to look at.

I simply took it off then places it back in, and it was fine.

The worst thing you really have to look for is making sure dust doesn't get in the display when you open it up. A canned air blaster is nice to keep dust off it.
