Alternatives
Certain beauty salon products that are primarily composed of hydrogen peroxide can also be used as an alternative to retrobright, as it has been discovered to be almost identical in effect, and already viscous so that it can be applied less wastefully to yellowed plastics (especially large devices such as computer panels or monitors). While this eliminates the difficulty of having to put together a batch directly from the instructions, one must be careful to apply the cream and wrap consistently and evenly to avoid streaks in the final product. Sodium percarbonate may also be used by dissolving it in water and following the usual steps for hydrogen peroxide, as it is sodium carbonate and hydrogen peroxide in a crystalline form. Ozone, Ozone gas can also be used for retrobrighting, as long as an ozone generator, a suitable container of sufficient size and a source of UV are available, but can take longer than other methods.Retrobright
Retrobright consists of hydrogen peroxide, a small amount of the "active oxygen" laundry booster tetraacetylethylenediamine, TAED as a catalyst, and a Ultraviolet#Sources of UV, source of UV. The optimum mixture and conditions for reversing yellowing of plastics: * A hydrogen peroxide solution (oxigenated water). * A source of Ultraviolet, ultraviolet light, from sunlight or a UV lamp. Xanthan gum or arrowroot can be added to the mixture, creating an easier-to-apply gel. In addition to homemade gel mixtures, hydrogen peroxide-based hair bleaching creams available at beauty supply stores can also be used as a ready-made mix.References
