Clear phone cases are normally made from silicone—a polymer that’s popular for its inexpensive and flexible properties.
Unfortunately, these polymers turn yellow as they age. This natural process is accelerated when they are exposed to excessive amounts of chemicals, light and heat.
Rather than just being a stain, the yellowing is part of the material degradation.
4 TIPS ON HOW TO CLEAN A CLEAR PHONE CASE THAT’S TURNED YELLOW
TIP #1: CLEAN WITH DISH SOAP
First, you should try to clean the phone case using dish soap. A simple cleaning solution and instructions are as follows:
Make a mixture of one cup of warm water (or 240ml) and a few drops of dish soap. Mix the solution together. Use a toothbrush to scrub the solution over the phone case. Work into all the nooks and crannies and clean it on the interior and exterior. Rinse it and use the soft cloth to dry it. Let it air dry for at least an hour to make sure it’s completely dry before putting it back on your phone. Repeat this process on a regular weekly basis to move excess oils and chemicals from your phone case that can degrade the material.
TIP #2: SCRUB WITH BAKING SODA
Baking soda works on various stains; however, it is not guaranteed to remove all of them.
To use this phone case cleaning hack, start by sprinkling baking soda over the phone case surface. Then, use a wet toothbrush to work the baking soda into the stain. Rinse the baking soda off and use a soft cloth to dry.

TIP #3: DISINFECT WITH RUBBING ALCOHOL
Disinfecting your phone is a good habit to practice on a regular basis. In addition, it is also a useful tactic to prevent phone case yellowing.
Use a spray bottle of rubbing alcohol or use a soft cloth soaked in alcohol to coat the phone case. Once the phone case is coated, use a clean and dry cloth to remove it.
Let it air dry for an hour before placing it back on your phone. Even if it doesn’t remove the yellowing, it will be free from bacteria and more hygienic.
Tip #4: Scour with Toothpaste and Paint Thinner
If all else fails, you could try using toothpaste and paint thinner.
First, cover the case in toothpaste, then scrub at it using steel wool. Then, rinse the toothpaste off, and coat in paint thinner. Again, work at it with the steel wool. Finally, remove the paint thinner with water.
