Why Do Phone Cases Go Yellow and What You Can Do to Prevent It?

Phone cases are a great way to protect your mobile device from scratches, drops, and other types of damage. But, have you ever noticed that after several months of use, some phone cases start to turn yellow? It's a common problem that many people experience, and it's not just a cosmetic issue. Let's explore why phone cases go yellow and what you can do to prevent it.

What Causes Phone Cases to Turn Yellow?

There are several factors that can cause your phone case to turn yellow:

1. Exposure to sunlight: Sunlight contains UV rays that can break down the polymers in your phone case. It's particularly a problem with clear or white phone cases that allow the sunlight to penetrate through.

2. Chemical reaction: Your phone case wholesale may react with chemicals present in your skincare products like hair oil or lotion. Most of these products have petroleum or silicone bases, which can interact with the plastic in the phone case.

3. Heat: If you leave your phone case on a hot surface, such as a car dashboard, the plastic can start to degrade due to the high temperature.

4. Age: Over time, the plastic in your phone case may naturally degrade, especially if you frequently expose it to the elements.

No matter what the cause may be, a yellow phone case does not look attractive, and it may make your phone look old or dirty.

How to Prevent Your from Turning Yellow?

Fortunately, there are several ways you can prevent your phone case from turning yellow. Here are some tips:

1. Choose a quality phone case: Picking a high-quality phone case made from durable materials is the best method to prevent yellowing. Look for cases made from materials such as silicone, TPU, and polycarbonate.

2. Clean your phone case regularly: Cleaning your phone case with non-toxic soap and warm water will remove oils, dirt, and other substances that can cause yellowing. Try to clean it once a week to keep it looking its best.

3. Keep your phone case out of direct sunlight: Try to keep your phone case away from direct sunlight. When not in use, store your phone case in a dry, cool place, out of direct sunlight.

4. Avoid exposing your phone case to heat: Try to avoid placing your phone case in high-temperature environments. Don't leave it in a hot car or on a heater for extended periods.

5. Don't use harsh chemicals: Avoid using harsh chemicals such as bleach or ammonia to clean your phone case wholesale. Instead, use a mild soap and water solution or a gentle cleaning spray.
