I have a laptop which means it goes everywhere with me, the screen constantly being adjusted and moved around, and it ends up needing a lot of polishing so I can see. So, whenever I polish the screen, I wipe the keys down too. Simple. But, it's a laptop. If someone dug in between the keys with a swab, I'm sure they could find all sorts of detritus that would grow into something nasty.
Out of 33 keyboards swabbed, four were regarded as a potential health hazard and one harboured five times more germs than one of the office's toilet seats.
During the Which? tests in January this year, a microbiologist deemed one of the office's keyboards to be so dirty he ordered it to be removed, quarantined and cleaned.
They also found that, compared to men, on average women have three to four times the amount of germs in, on and around their work area.

Take the model name of your laptop and google "removing keyboard tray from "model name"
Here is a generic guide:

Goto a male washroom and it smells like an outhouse at a beach during low tide..... go into a female's washroom and it's got flowers all over the place, fancy wallpaper which hasn't begun to peel from the stink, nice colorful soaps and just seems like a cleaner environment all together.......
Does this mean female washrooms are so clean because they take their dirt with them to their keyboards? :P

Smell and appearance aside, women's washrooms have been found to harbor way more bacteria and nastiness than men's bathrooms. Keep in mind that public women's bathrooms often have diaper changing facilities, women always have to wipe (thus almost always transfer extra bacteria), and, women menstruate, which means inevitably that they're dealing with all sorts of extra disposal containers and chances for bacteria transfer than men's bathrooms.

I read somewhere that most keyboards can withstand being washed in a dishwasher

I read an article on it. They tested a few different kinds. The important thing was that the keyboards were unplugged when the water hit them and they were TOTALLY dry when they were plugged back in. I know it sounds like a bad idea, and I'm sure they're not designed to withstand that treatment, but I know it has been done with success.
