Many people like clear phone cases because they show off the phone’s design while also keeping it safe. But a downside is that these cases can turn yellow as they get older. This can make them look less attractive. Let’s look at why this happens and how to stop it.
Clear phone cases can turn yellow over time for a few reasons. One big one is sunlight – those UV rays can break down the plastic and make it change color. This process is called photodegradation and it’s why clear phone cases can get yellow. Heat and humidity from the environment can also play a part in causing this discoloration.
Another reason why clear phone cases turn yellow is because the plastic material naturally ages. As time passes, the compounds in the plastic can break down, causing discoloration. Factors like heat, sunlight, oils, and other substances can speed up this process. 
Aside from the environment, the type of materials used in the phone case can also affect how fast it yellows. Cheaper plastics are more likely to yellow compared to higher-quality materials. To avoid yellowing, it’s important to choose a clear phone case made from high-quality materials.
Now that we know why clear phone cases turn yellow, let’s talk about how to stop it from happening. One easy way to prevent yellowing is to keep the phone case out of the sun. You can do this by putting the phone in a pocket or purse when you’re not using it, or by using a case that covers the whole phone instead of just the back. Also, keeping the phone in a cool, dry place can help stop yellowing caused by humidity and heat.
Here’s another tip to keep your phone case from turning yellow: make sure to clean it regularly. The oils and dirt from your hands can build up on the case, causing it to change color over time. To clean it, just use a gentle soap and water mix or a plastic cleaner designed specifically for this purpose. Stay away from strong chemicals or rough cleaners, as they can harm the plastic and make it more likely to yellow.
Besides cleaning the phone case, you could also think about putting on a protective coating or sealant to stop it from turning yellow. These products form a shield between the plastic and outside elements, which can help slow down the wearing process and maintain the phone case’s fresh look for a longer time. Just make sure to follow the guidelines from the manufacturer when applying a protective coating to get the best results.
In order to prevent your phone case from turning yellow over time, it’s a good idea to invest in a high-quality clear case made from strong materials. Even though these cases might be pricier at first, they are typically more resistant to wear and tear from the environment, keeping them clear for longer. Consider getting a phone case made from materials like polycarbonate or TPU, as they are known for their durability and ability to stay clear.
In summary, clear phone cases can turn yellow over time because of things like being in the sun, getting hot, and touching oily substances. To stop this from happening, try to keep your phone case out of the sun, clean it often, maybe add a special coating, and choose a good-quality case made from strong materials. If you follow these suggestions, you can help your clear phone case stay looking fresh and in good condition for a longer time.
