When a British study recently showed the average computer keyboard is dirtier than a toilet seat, Jacqueline Miller's worst suspicions were confirmed.

Miller is a professional computer cleaner based out of Toronto who balances her time between educating business about IT sanitation and actually ridding them of germs herself. One of her big challenges is raising awareness that this is a problem. She said there's a lack of research available to address the Canadian market specifically.

"We can guess that Canada is similar to the United States," she says. "But even with Stats Canada, the most recent information I can get on the amount of sick time people take (due to illness) is from 2005. Do people not care about sick time?"

Miller offered an insider's view of the dirty world of office computers with ComputerWorld Canada. What follows is an edited transcript of her conversation with us.

How did you get started as a computer cleaner?

Back in the mid-80s -- without saying I'm old or anything -- I was in operations, and part of our responsibility was cleaning the computer room, because of dust and static. So you had to get the suction cups and lift the floor boards. Of course, computers really started coming in to offices in the mid 1990s, and part of my job then was training secretaries how to use a computer. Although they've now been around for a long time, no one really thought about that process of cleanliness, and it's not until all the illnesses got passed around that people started questioning it. (Later), around 2000, there was an opportunity in a company I was doing some work for, again with the computer room. No one ever cleaned it, and the IT guys are just too busy, so a couple of us teamed up. We had to organize a little business, and from that point on there were phones and things there where they said, "Could you do the call center?" So I've been doing it for several years.

How can you do a good job of cleaning keyboards and phones?

It's got to start at home, with washing your hands. You can't disinfect a dirty surface. And people don't know that. I've called Clorox and Lysol and all those companies, because if you look on the back of those products and it says it's 98.999 per cent effective, that's based on a thoroughly clean surface. So you can wipe your keyboard every day, every week, but if it's not clean, you can't maintain it.
