5 Ways to Keep Your White Phone Case from Turning Yellow

Direct Answer: How to stop a clear phone case from turning yellow?

To prevent a clear or white phone case from turning yellow, keep it out of direct sunlight to avoid UV degradation, wash it weekly with mild dish soap to remove hand oils, and avoid harsh chemicals like bleach. If you want a permanently clear case, upgrade from cheap TPU silicone to a hard shell Polycarbonate (PC) case.

The Battle Against Yellowing

There is nothing quite as sleek as a brand-new white or clear phone case. However, keeping it pristine is a constant battle against the elements.

1. Keep It Out of Direct Sunlight

Ultraviolet (UV) radiation is the primary culprit behind TPU (thermoplastic polyurethane) yellowing. UV rays break down the chemical bonds in the polymer, causing an irreversible color change. Avoid leaving your phone on sunny windowsills or car dashboards.

2. Clean With Mild Soap Weekly

The oils and sweat from your hands react with the case material over time. Wash your case once a week with a few drops of mild dish soap and warm water using a soft toothbrush.

3. Upgrade to Polycarbonate (PC)

If you are tired of the yellowing battle, stop buying TPU silicone cases. Upgrade to a Hard Shell Polycarbonate (PC) case. PC does not undergo the same chemical degradation and will remain clear or brilliantly white forever.
