Vive Pro Controller Discoloration - Seeking Guidance

[Anarose192]

I've recently noticed some discoloration on one of my Vive Pro controllers. It's a bit concerning, and I'm wondering if anyone else has experienced a similar issue. The discoloration doesn't seem to be related to any physical damage, as the controller functions perfectly fine. Has anyone encountered this issue before, and if so, were you able to address it? I'm open to any advice or recommendations you may have.

Thank you for your help!
