プラスチックの黄ばみを取る方法（太陽光で黄ばんだプラスチックを白くする）

Is there a yellowed plastic product used for remote control and white goods in your home? Except for the yellowing that has become dirty due to external factors such as cigarette tar, the plastic that has naturally turned yellow does not return to its original color even if it is dressed with detergent. This is because the yellowing of plastic products occurs due to the chemical change of the additives contained in the ABS resin used as the raw material of plastics. Discoloration caused by normal chemical changes can be restored by chemical changes. In this video, I would like to introduce you to the methods I usually use to whiten and bleach plastics that have turned yellow due to chemical changes by causing a chemical reaction with hydrogen peroxide and ultraviolet light. Please refer to it.
