Just be careful with it if you do go that route. I did the Salon peroxide + water and heat method and my mouse ended up like Casper :/
But I've seen good results from others who've done it. I did the fascia of my 4400 under a blacklight, and that was
okay, if a bit time-consuming (painting on more paste every so often). Most people have luck with the plastic wrap or plastic bag, but that seemed just as labor intensive. What I liked about the blacklight method was that it was SLOW and I could control by the hour what level of "bleaching" level I could achieve.
A well-documented series of tests performed by a university(?) in Denmark seem to suggest that in the long-term it might to more harm than good for the integrity of the plastic itself, but for the short term, aesthetic desires, it's probably the only option to get the original coloration back. I can't find that study at the moment, but it's out there...
