> My otherwise mild skin condition completely destroys the shitty grippy/gummy rubber they put on scrollwheels and sometimes the sides of the mice.

I’m not sure it’s even skin conditions. I think it’s just the natural oils in the skin. It’s part of what polishes plastics (e.g. keyboard keys), and over time it impregnates the rubber which swells then falls apart.

This process is why wet belts are stupid, no reason to think mouse wheel rubber is any different.

I agree with wet belts - it's a terrible idea - but I'm not sure the comparison is great. Skin oil and synthetic oil are very chemically different - as are the rubbers used in a cheap mousewheel versus an engine belt.

I have to wipe my kit down with soapy water every few hours or they will be caked with a disgusting amount of dead skin. My fingernails after 4 days are about as long as typical people after 2 weeks.
