I did not think about sanitising the controller. I use it a lot but I'm mainly the only one using it. I hope my friends sanitise it though They don't visit me that often but we hang out together a lot at one of us's place
I use the disinfecting wipes, like previous posters mentioned. I've also wiped them down with alcohol pads, but we tend to keep Lysol disinfecting wipes around more than alcohol pads, so that's what I use most of the time. If you use alcohol pads though, make sure you don't touch the controller until the alcohol evaporates - that's what kills the germs!
