Keep it Clean
Something that's been important to me for as long as I can remember is keeping my accessories clean. Having to use other's dirty controllers made me not want to play games at all. So nowadays I have regular cleaning days for my things: controllers, keyboard, screens, surfaces. I personally prefer deep cleaning as well and try to take things apart as much as possible and soak the plastics. It's nice knowing everything will last longer as well. Give it a shot sometime and appreciate your stuff being 'like new' again.
