I was commissioned to restore a G1 Scourge back to a better state. I cleaned it up, disassembled him and gave the severely sun-faded pieces a hydrogen peroxide bath. I used 9% strength but I'm thinking I may have got better results with 12%. The sun fading is still slightly visible, but I'm sure you'll agree it's a huge improvement from what it was to start with.
Interesting to note that the hydrogen peroxide did not effect the rub sign at all! Still works like new.
I finished the job with a fresh set of stickers from reprolabels.com.
