Why Clear Phone Cases Turn Yellow (and How to Prevent It)

Clear phone cases look sleek and stylish when brand new, but many people notice that after a few months, the once-transparent material turns yellow. This can make your phone look old and dirty, even if it’s well-protected. Why does this happen? And more importantly, how can you stop it? In this guide, we’ll explain the science behind yellowing cases, share tips to prevent it, and help you keep your OtterBox clear case looking fresh for longer.

Why Do Clear Phone Cases Turn Yellow?

Clear cases are often made from TPU (thermoplastic polyurethane), a flexible plastic that reacts to:

UV light from the sun.

Heat and humidity in the environment.

Natural skin oils and dirt from daily use.

Over time, these factors cause the material to discolor, leading to the yellow tint you see.

How to Prevent Yellowing

While some discoloration is natural, you can slow it down with a few habits:

Clean your case regularly with mild soap and water.

Avoid harsh chemicals (like alcohol or bleach) that can worsen discoloration.

Keep your phone out of direct sunlight for long periods.

Use microfiber cloths to wipe away sweat, oils, and dirt.

💡 Pro tip: Rotating between two cases can extend the life of your clear OtterBox.

Can You Restore a Yellowed Case?

Unfortunately, once the plastic has yellowed deeply, it can’t be restored to perfect clarity. Some surface discoloration can be reduced by:

Soaking in a gentle soap-and-water solution.

Scrubbing with a baking soda paste (for light stains).

Using a UV phone sanitizer (helps reduce bacteria, not color).

If the yellowing is severe, it’s usually time for a replacement.
