I have never cleaned a controller. Ever. I did have one of my PS3 controllers go bad (super sticky buttons). I took it apart, and was never able to get it to work properly, so it went in the trash can. Another one of my controllers is slow to respond, and I've never figured out why, but my blue controller has been flawless for 3 years now.
Money can't buy happiness. Just video games, which make me happy.
