I knew a fellow who worked in IT. Long before "washable" keyboards came to the market, he wondered if a keyboard could survive a ride in a dishwasher.
It did!
The key factors were:
- DO NOT use ANY kind of dishwashing compound. Hot water jets are sufficient to do the job.
- DO NOT use any of the sterilize" or "pot scrubber" cycles unless you want to alter your keyboard's topography in a MAJOR way.
- You MUST allow the keyboard to dry for a couple of days before connecting it to your computer.
The keyboard he used was a Sun Microsystems type 5 ketboard, which was one of the first to use the "blister" style switches on the keyboard.
