R5 (and other cameras) rubber parts swelling

I've had my R5 since it launched, so about 4 years, and I'm noticing more and more of the rubber parts on it swelling. I think this happened to some degree with my previous cameras too. The cover for the mic/headphone ports doesn't quite fit right, the front grip has swollen a little bit and come detached from the body, and now I just noticed the eyecup has popped out of where it's supposed to slot onto the camera because it's swollen too. I don't know for sure what's causing this. My only guess is that I sometimes wear sunblock during the summer when I'm outdoors. That's really the only foreign chemical substance that I can think of that ever gets near the camera. Has anyone else had this happen, and is there any way to stop it, short of not wearing sunblock any more which I'm not willing to do? Thanks.
 
Greetings,
Have to hear what others say. I've never had a camera's rubber or plastics parts swell. I won't hold my camera with anything on my hands. Food or any types of lotion. At parties I sometimes double fist... camera in one hand, drink in another. I always use a BR wrist strap, or sports breathe. No fumble or slips. I wear hats in the sun. Full on safari. Skin cancer is no joke. Carry wet wipes. Might be time for your camera to visit Canon.

No DEET bug repellent involved? Ever in very hot vehicles? Other extreme temp changes? Not to be personal, but do you live in a place with higher than average pollution?
I wear DEET pretty rarely. And regardless I *know* that stuff is really aggressive at attacking rubber and plastic. I wouldn't let it near my camera.

I try to avoid leaving camera stuff in a very hot car. Sometimes it's unavoidable, but I avoid it if at all possible.

Other extreme temp changes?? Well, I mean the camera is not a studio queen, so I guess yeah, sometimes? But no more than I go through in normal life, and I'm still alive.

Well, I'm just outside of Detroit, so the air is not great, not the world's worst.

Anyway, I found a new factory eyepiece on ebay. That was the most blatantly swollen part of the camera. I might hunt down a new front grip, but honestly I feel like it's just going to happen again.

I don't understand the suggestion of sending to Canon just for a few swollen rubber parts. I mean, I get it, I guess, but really, all that cost and time without my camera just to replace things that I could myself if I found the replacement parts?

I wonder where do you store your camera when not in use?
