Hardware tricks to remove scratches from the screen?!

[darky2003]

I just got myself a fat vita with one game for 50€.
Good deal if u ask me.
The only con is, i'm a person who can't stand scratches and there a a few i would like to get out.
So i was wondering if there's any way to get rid of a few scratches.

I know there a few tricks floating around to get rid of scratches like toothpaste...
Also i found this one but i'm not sure if it will do the trick:

I'm scared to replace the front screen because i don't wanna put my vita in the oven

Plz someone tell me what products are safe to use on my oled screen.
