UV-light

Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays.

, the bromide comes to the surface of the ABS plastic, and the yellowing begins. Unfortunately, even after treating the item with Retr0bright, the yellowing returns after 3-4 years, looking worse than your grandfather's underwear.

Is Retrobright permanent?

Technically, nothing is permanent :) I know a quality retr0bright treatment will last many years when the computer is stored in a friendly (low heat and UV) environment.

How long does it take to Retrobrite?

When all parts are coated and wrapped, leave them to sit out in the sun. The process can take anywhere from 6-8 hours depending on the amount of heat and sunlight available. Flip the parts around every 1-2 hours so all sides can get the sunlight they need for the gel to do its job.

Does Retrobright make plastic brittle?

But I hear the Retrobrite process can weaken the plastics of each console case and make them very brittle, which is a bad thing.

How do you use Retrobright plastic?

Retrobrighting requires two ingredients: hydrogen peroxide and a source of UV light or heat energy. All parts to be retrobrighted need to be very thoroughly cleaned in warm soapy (dishwashing fluid) water, very thorougly rinsed and completely dried.

Can yellowed plastic be restored?

Using Peroxide to Clean Yellowed Plastic

Pour straight peroxide in a container. Put the plastic in the container. Allow the plastic to soak in the sunlight until the stain lifts. Rinse and dry.

Why do old computers turn yellow?

This yellowing happens thanks to a flame retardant called bromine in those old ABS plastics. When exposed to UV light, those bromine molecules can destabilize and leech through to the surface, causing the plastic to turn yellow (or even brown if left long enough).

Will 3% hydrogen peroxide whiten plastic?

Here are my thoughts about using hydrogen peroxide to clean yellowed tupperware, plastic utensils, and stained plastic dishes: Be patient. Use 3% hydrogen peroxide, but expect that it may take more than one attempt to get the stains off. Give the peroxide time to work.

How do you reverse yellowing plastic?

Coat your yellowed plastic gadget and wrap it. In a nutshell, all you need to do is to coat the plastic (cleaned and dried, of course) evenly with the cream peroxide. Avoid having the cream coming in contact with your skin or eyes, as it can cause burns.

Do you need heat for Retrobright?

Temperature is VERY important and should REALLY never be higher than absolutely necessary.

Does UV light whiten plastic?

Whitening process. The reverse process uses commonly available 6% or 12% hydrogen peroxide and UV light as catalyst (can be common UVA bulb or even simple sunlight) to activate the whitening reaction. Ultraviolet light bombarding hydrogen peroxide generate very active hydroxyl and restore the original color.

Does peroxide whiten plastic?

Coat the yellowed plastic in hydrogen peroxide using this simple process: put the plastic in a plastic bag with enough hydrogen peroxide to cover it entirely (ability to submerge depends on the size of the object), and leave it in direct sunlight for three to four hours.

What causes ABS plastic to yellow?

Yellowing in ABS plastic occurs when it is exposed to UV light, among other factors, which causes photo-oxidation of polymers that breaks polymer chains and causes the plastic to yellow and become brittle.

Does hydrogen peroxide weaken plastic?

H2O2 is a strong oxidizer. I wouldn't even dare try it on anything metal. On plastic, it would perfectly be fine as long as it's not the industrial 35% grade.

Why has my white bath panel gone yellow?

Do all plastics turn yellow?

The ultra-violet spectrum of light doesn't play well with most polymers — unless, of course, you add light stabilizers, but we'll get to that in a moment. Exposure to UV radiation can cause plastics to change color (turn yellow), crack, break, shatter or even melt!

Can you soak plastic in bleach?

Yes, it is corrosive to plastic. It does not eat up the plastic in one go (we are assuming you are using the diluted bleach or bleach water as the cleaning agent), but the damage it would create is definite.

Can I use hydrogen peroxide?
