I can't say for sure and for all locations on campus, but I know in most places like Norlin, they are not wiped frequently at all. I usually use my laptop, but I do wipe down public keyboards with sanitizer and a tissue when I use them. I'm sure at least some other people do the same. I did notice however, that after Spring break, some of the keyboards looked like they'd been cleaned (in Norlin and Clare Small). I assume they do this only once or twice a semester. Gross.

I don't think if they are wiped, it is done very well. In my microbiology class i swabed a few key boards and some stuff did grow. I mean when you look at the key board and certian letter are black from being touched you have to assume its dirty and not being cleaned regularly

The cleaning crews at night wipe down the computers and the keyboards so don't worry it's clean
