>>10831910>orange-ish due to ageThe dye in the white plastic oxidized, aka rusted. You can fix this very temporarily with hydrogen peroxide, but since it's opening up millions of microscopic holes it will come back way WAY worse than if you just left it alone. Pic related was an experiment to clean one side of an oxidized brick and leave it for a year. The left side was the one that was cleaned. It was bone white after cleaning but after one year it became worse than if I just left it alone.
