Just acquired a XEGS. The color isn't too bad, but the buttons have yellowing on the edges, and the console has yellowing on the edges, sides, and bottom.
I know that the 40% hydrogen peroxide cream works well on restoring SNES's back to their white, but will it work with restoring the XEGS back to the gray? Essentially, I'd be bleaching the plastic, so I'm concerned about making the XEGS too bright or white compared to the original color.
Also, would it work on restoring the original color of the buttons?
