Playing League for Long Periods of Time and Dead Skin / Sweat?

Hello League Players,

I was just wondering how to deal with dead skin and sweat build up on my keyboard and mouse? I don't know if this happens to anyone else, but I don't really get sweaty to the point where my fingers are noticeably moist with sweat. But still on my Razer Blackwidow Chroma and my Logitech G600 mouse there is always some gunk build up, which I believe to be dead skin / sweat. And this only happens when I am at my computer for 2 or more hours. But when I am on my computer for that long, I wash my hands like every hour roughly (I go to wash my hands after my game ends, and before I start a new game). Is this like something I need to talk to a doctor about? Or maybe like get some hand cream? Or are keyboards and mouse just prone to collecting all this skin and sweat, and I just need to constantly clean my keyboard every few hours?

Thanks for any help.
