Does anyone know of a way to remove a scratch from an original Game Boy screen? I just bought one recently and it's in perfect condition apart from one very small scratch on the screen. I'd like to try to repair this if possible but I'm not sure if it's worth the hassle or not?

I've already cleaned the screen so I know it's definitely a scratch, not dirt or dust. I've used a polishing cloth (without any polish) but this hasn't done anything.

I guess what I'm looking for is maybe some slightly abrasive polish or something similar. If anyone has tried something like that please let me know what you used and how it turned out. I don't want to end up with a dulled or very shiny area on the screen so I thought I'd ask here before trying anything.
