Did you use a gel or sink the case in hydrogenperoxide?
Does a longer and harsher treatment degrade the surface significantly more?
I haven't ever noticed any surface degradation. Longer exposure and allowing the creme to dry and "bake" onto the case will almost invariably cause bleaching.
Another potential bleaching hazard is when using a UV light that is a bit overpowered. A strong UV light, in my experience, can cause bleaching in the plastic rather easily. Always be careful when bleaching darker colored plastics.
I had a UV wash light that was the equivalent of a 100W bulb, I think. It was very strong, too strong in fact. It didn't necessarily bring results quicker either.
Ultimately I bought a UV LED light bar for my retrobrighting needs and it works well and has excellent coverage while not being harsh at all.
