Why is the transparent phone cover yellow and how do you prevent yellowing
Causes from which transparent covers are yellowed
In the manufacturing process the covers are not transparent. The material from which they are made has a yellowish color that by combination with shades of blue, the producers manage to give them white - transparent to plastic or silicone housings.
It is a chemical treatment to which they are exposed to obtain transparency. With the passage of time, there are two main factors because of which the transparent cover is yellow: prolonged exposure to UV radiation (in the sun) and contact with sweating on the hands.
However, not all phone covers are yellow as quickly. It matters a lot and the material from which they are made. For example, a thermoplastic polyurethane housing (TPU), is prone to oxidation. Oxygen in the air can react with the materials in the case, resulting in its yellowing.
The same thing happens with poor or poorly manufactured phone covers can contain additives or impurities. They are more susceptible to yellowing in a relatively short time.

How do you prevent the yellowing of the transparent case
If you are a fan of transparent covers and you do not want to become yellow in color, here are some tips to keep in mind:
1. First, the quality of the materials matters a lot. Choose a high quality phone case, made of materials specially designed to withstand yellowing, such as polycarbonate. It can be seen in the image above how well it has resisted over time.
2. Do not expose the phone to ultraviolet. Keep the phone and the case distance from direct sun exposure or prolonged UV rays.
3. Avoid exposing the phone case to excessive heat or storing it in hot environments. The heat will destabilize the chemical structure of the materials from which the case is manufactured and it will take on a yellow color.
4. Be careful when using cosmetics or oils around the phone, as they can stain or interact with the cover material.
5. Clean the phone cover regularly using soap and water or special cleaning solutions that do not destroy its chemical treatment.
Note that, even with proper care, it is possible to appear a certain discoloration over time, especially in the case of transparent covers of certain materials.
