Good thing to see I'm not the only one that cleans consoles, controllers and games, I can't stand dirt and grime especially on a controller. I always try my best to wash my hands before I play a game.

Also I do like people to bring their own controllers so one they can't complain your controller sucks and yes I'm one of those that don't like other people using my controllers. My immediate family or boyfriend are exceptions to the rule however, but of course clean hands equal clean controller with minimal dirt.

As for Genesis controllers, I've never had a problem with one, after a good contact cleaning they usually respond much better than before.
