I have an idea, if you want it, you can patent it. :-)

How about a "fast keyboard cleaner", which would be a handheld device, and could clean a keyboard "like a fast car wash". It would be about 10 inches wide, and would be moved slowly from left-to-right across the keyboard. The first stage would be a rotating wet bristle brush, kept soaked with a germicide-viricide mixture. It would be fed to a wet-dry vac for collection. That would be followed by a strong UV light and hot air blow-dry section. It probably would be a 2-part tool...first wet-brush-vac the keyboard, followed by a 2 minute UV-blowdry under a shoebox-size cover.

I bet you could sell millions of them to health care organizations.

Ok, I'll retire now. ;-)
