Clear phone cases are widely loved for many smartphone users. While also offering protection they provide a sleek, minimalist design that helps the phone's natural beauty to shine through. But many people who use clear phone cases notice that their clear phone case quickly becomes yellow and  look unappealing. In this article, we will explore why clear phone cases become yellow, how you can prevent it and share some tips on how to clean yellowed cases. We’ll also show you the best five clear phone cases from TORRAS. So without further ado, Let's get started.

 

Why Do Clear Phone Cases Turn Yellow?

 

Clear phone cases, especially those made from plastic or rubber-like materials, tend to yellowing over time. This happens for several reasons:

 

1. Exposure to UV Light

 

Ultraviolet(UV) is the main reason of yellowing in clear phone cases. Sunlight can break the chemicals in the plastic, causing it to oxidize. This oxidation leads to a yellowish color, which becomes more apparent with time. This often happens with clear Apple phone cases because they are usually made from materials like polycarbonate or TPU (thermoplastic polyurethane), which are easily affected by UV rays.

 

2. Oil and Dirt Build-Up

Another major reason to the yellowing of clear phone cases is the accumulation of oils from your skin, makeup, and dirt. Over the time, the oil from your fingers or face will slowly seep into the material of the case and with dirt, it speeds up the yellowing, especially where you touch it most.

 

3. Environmental Factors

The yellowing process accelerates because of some environmental conditions too. For instance, if some one is living in a very polluted environment, smoke, or in high humidity, these environmental conditions can further weaken the material of the case and make it yellow. Moreover, constant heat can break down the plastic and result in discoloration.

 

4. Low-Quality Materials

The  materials used in a clear phone case can play a role in maintaining its longevity and resistance to yellowing. Cases made from inexpensive plastic materials or lower-grade quality TPU are more likely to yellow faster compared to high-quality, premium cases.

 

Methods to Prevent Your Clear Phone Case from Turning Yellow

 

Although yellowing is a natural process that happens over time, you can take different steps to prevent it from occurring permanently. Here are some helpful tips to maintain your clear phone case :

 

1.Avoid Prolonged Sunlight Exposure

As UV light is one of the primary causes of yellowing, it’s best plan not to leave your clear phone case directly under the sun for extended periods of time. Always attempt to keep its direct exposure to UV rays at a minimum and store it in a cool, dry location when not being used. If you must have your phone out, use a case with UV protection or a screen protector to protect it from sun.

 

2. Routine Cleaning

Cleaning your phone case regularly is one of the best methods to avoid yellowing. To avert discoloration, clean your case frequently with a microfiber cloth or soap and water. Dry the case thoroughly after cleaning to ensure no moisture, which can weaken it over time.

 

3. Apply Anti-Yellowing Coatings

A few brands have begun adding special coatings to their clear phone cases to avoid yellowing. These coatings keep the case from UV light and oils and dirt as well. These coatings protect the case from UV rays and oils as well as dirt. Always try to choose cases with anti yellowing technology for extra protection.

 

4. Keep Your Phone Away from Dirty or Oily Surfaces

In order to minimize the amount of dirt and oil be cautious about where you place your phone. Paying attention to where you set your phone can minimize the amount of dirt and oil that it comes in contact with. Avoid having your phone on dirty surfaces and try to keep your hands clean when you use it.

 

How to Clean Clear Phone Cases

 

Despite proper care, your clear phone case may still yellow over time. If you’ve  noticed yellowing don’t worry – there are different cleaning methods to restore its original clarity. Here are a few options:

 

1.Soap and Water

The simplest way for cleaning a yellowed clear case is by using soap and water. Add a few drops of mild dish soap with warm water and soak the case around 15 minutes. After soaking, wash the it gently with a soft cloth or sponge, particularly on yellowed areas. Wash the case well and dry it with a clean towel.

 

2. Baking Soda and Toothpaste

Baking soda is a quick and easy cleaning solution for removing yellowing from transparent phone cases. Just make a paste by combining baking soda with a little water or toothpaste. Apply the paste to your case’s yellow spots and scrub lightly with a soft brush or cloth. Wash the case well and dry it. This process can restore some of the clarity of the case, but it might not eliminate  severe yellowing.

 

3. UV Light Treatment

Some people have had success using UV light to reverse yellowing. There are special UV lamps that can break down the yellowing in certain phone cases. It may not be effective for all cases, but it is a good option for stubborn yellow stains.
