How long does retrobrite take?

Answer 1

Retrobrite typically takes anywhere from a few hours to a couple of days, depending on the method used and the severity of the yellowing. The process involves applying a hydrogen peroxide solution to the discolored plastic and exposing it to UV light, which accelerates the whitening effect. Factors such as the intensity of the UV light and the thickness of the plastic can also influence the duration. Regular monitoring is recommended to achieve the desired results without over-bleaching.
