Good suggestions everyone...I'm going to use some of them. I'm pretty phobic about germs, too, and keep a container of Clorox wipes on the desk next to the keyboard and wipe it down several times a day....both of my sons use this computer, too, and I'm willing to bet they don't wash their hands as many times as I do.
Now that I've thought about it...I'm going to buy a new keyboard. It's been a while and the "N" and "E" are invisible...as in rubbed off.
Oh, and my keyboard doesn't have any smell to it...I waited until I was sure nobody was around and smelled it. Nope...no smell!
