[QUOTE="peekaygee73, post: 453418, member: 6023"] What concerns people is the long term effect of using hydrogen peroxide on plastic. I'm no chemist, but my understanding is the plastic has already been damaged and discoloured through photodegredation, and the hydrogen peroxide attacks the yellow pigment before attacking the colouring of the original dye in the plastic. Generally any changes in colour attained using hydrogen peroxide are short-lived, so you'd have to keep using it which can (and as has been mentioned above does) cause further damage to the plastic.
