Why Clear Cases Turn Yellow. Make sure to also reach the corners before wiping the case with a clean microfiber cloth. I did however wear out the plastic a little bit cuz I was a little.

This will help prevent the yellowing from occurring. I ended up just rubbing the yellow out with some eraser I had on my desk and it worked out perfectly. Depends on the plastic and quality.
It is much more durable flexible and shock absorbing than silicone and hard cases but tends to yellow overtime.
Yes the sides turn an ugly brown color in less then a month of light use. I had this happen on one of my translucent TPU cases. The chemicals in the case. I can confirm that.
