"Wulfman" In one extreme instance, I DID try to wash out a keyboard.......only to ruin the keyboard (it may have been "toast" anyway). But, I found that I usually had to shake them out before I took the canned air to them.
When I worked at a wealthy prestigious health care institution, I was given a very used, imprinted, stained, disgusting wrist support for my computer nearly barfing at the presentation. The giver of the goods left. She returned with a wet nasty, disgusting wrist support. I scooted my trash can in her direction and suggested she allow it to air dry there.........as a welcomed new employee, I purchased my own supports and a couple years later, this prestigious health care institution fully paid for my carpal tunnel surgery and full short term disability pay for the month I had to be on FMLA for each hand!!!!
I think that gross, disgusting, imprinted, overused and wet nasty "support" would have found you, Den, disgusted as well!!!!
