- Transparent phone covers are made of TPU, which oxidizes and turns yellow.
- The polymer chains of the cover react with UV light, heat, oxygen, and skin oil.

- For excessive yellowness, hydrogen peroxide can be used with caution.
Phone Cover: Many people use transparent covers to provide protection while maintaining the look of the phone. These do not spoil the look of the phone, but after using it for some time, they start turning yellow. Due to this, the phone starts looking old, due to which one does not feel like using the cover. Today we are going to tell you why phone covers start turning yellow and what should be done to clean it.
Why does the phone cover start turning yellow?
Most transparent phone covers are made of thermoplastic polyurethane (TPU). This plastic is flexible and also tolerates shock if it falls. Besides, it is cheaper for the manufacturer to make it, but it also has one drawback. It starts getting oxidized after some time. When this cover comes in contact with UV light, heat, oxygen and skin oil, its polymer chains start reacting. With the help of these reactions the cover starts appearing yellow or brown in a short time. Even if the cover is kept completely clean, it will start turning yellow after some time. In some covers, companies add UV stabilizers or anti-oxidation additives, which slows down the yellowing reaction, but does not stop it completely.
How to clean phone cover?
No matter what type of cover you are using on the phone, it is important to clean it at regular intervals. For this, remove the cover from the phone and leave it in water for some time. Now mix some soap in water and scrub the cover with gentle hands. If there is any stubborn stain on the cover, then to clean it, rub baking soda on a brush. After cleaning, wipe the phone with a clean cloth and dry it thoroughly.
How to remove yellowness from phone cover?
It is quite difficult to prevent the transparent cover from yellowing, but with frequent cleaning it can be used for a long time. If the cover of the phone has become very damaged and has started appearing completely yellow, then it can be cleaned with hydrogen peroxide. Keep in mind that do not apply this chemical directly on the cover. Doing this may damage the cover.
