Hey there. New here. But, ive been wanting to know if anyone has answers to it possibly- for collectors items that are still in the plastic, ive always wondered how to maybe reduce some of the yellowing on the packaging, but unsure if thats even possible if the plastic has been holding the colour for that long…any suggestions? (Theres some sonic toy island and resaurus figures ive been eyeing for a while but a lot of the ones that are affordable happen to have deep yellow plastics on them.)
The only way I've read to restore yellowed plastic is using hydrogen peroxide paste and UV light (or direct sunlight), but that method is for the action figures themselves, not the packaging.
