Feb 21, 2025
That crystal-clear phone case you proudly sported just a few weeks ago? It's probably not so crystal clear anymore. Clear phone cases, while stylish and protective, have a tendency to attract dirt, grime, and that dreaded yellowing.
But don't despair! Restoring your case to its original glory is easier than you think. This article outlines four effective and simple methods to clean your clear phone case and keep it looking brand new.
Why Do Clear Phone Cases Turn Yellow?
The yellowing of clear phone cases happens due to a combination of environmental and chemical factors. Here’s why it happens:
- Oxidation:Most clear cases are made from thermoplastic polyurethane(TPU) or silicone. These materials undergo oxidation when exposed to oxygen, leading to a gradual yellow tint.
- UV Exposure:Sunlight and artificial lighting contain ultraviolet (UV) rays, which break down the molecular structure of the case, causing it to discolor.
- Heat and Moisture:Warm temperatures and humidity accelerate chemical reactions in the case material, speeding up the yellowing process.
- Oil and Dirt Build-up:Everyday exposure to sweat, skin oils, and dirt contributes to discoloration. Even placing your phone on different surfaces can transfer grime onto the case.
Now that you know why your clear phone case turns yellow, let’s go over four simple and effective ways to clean it and save money.
