"Yellowing" Clear phone case- any ideas?

[skyandcosmos]

Hey all, I've been using a clear Ringke case for my G6 for the past couple of months. I've just noticed that the corners of the case are starting to turn yellow. It doesn't seem to have affected the phone itself (yet) but was just wandering is there any way to prevent / clean this? Thanks.

My guess is it's just discoloration, similar to how plastic headlight lenses yellow over time. I wouldn't worry about it affecting the phone.

 

[sure why not]

I have a Ringke case on my phone right now.
Purchased a new one recently because the tpu sides started to tear away from the pc backplate.
Yellowing is normal over time and due to oxidation and environmental factors.
The 'stain' is *in* the plastic, so there is no way to clean it off.
