Usually they leave it in the sun with retrobrite applied (which I believe is pretty much just hydrogen peroxide)

  Yeah. I've done this a few times with plain old hydrogen peroxide. However, I also really do wonder if the hydrogen peroxide is even needed... it seems to help, but it's unclear. It's frustrating how unscientific retrobrighting is; it clearly works but it's so weirdly spotty that it's hard to conclude anything, with effort it usually works to some degree but when it does and doesn't work is a mystery (and people often mistake accidentally bleaching the parts for success, which muddies things even worse.)
