Washing your keyboard in the dishwasher is a *very* bad idea for several good technical reasons. The inner workings of most modern "quiet" bubble dome keyboards is usually one(1) chip, and three thin mylar membranes. The key presses down on the "bubble dome" which pushes the top membrane through a hole in the second to make contact with a land pattern on the third. If you get water between those thin mylar sheets it will not air dry for six months... if ever. Not to mention the "chip" is very sensitive. Shorting it makes it stop working, and usually destroys it. The second problem is that soap film residue from the dishwasher will cause the keytops to stick without mercy. Having said all that... there are some modern "sealed" keyboards... but they are like sealed
Timex watches... there is no guarantee, and all it takes is a "drop" of water to can the keyboard. The proper way to clean the keyboard is to disassemble it, remove the sensitive guts, and then wash the "top" and "keytops " with clean fresh water... no soap... allow to thoroughly dry... and then reassemble. Uh, no, I will never be placing my keyboard into the dishwasher... ever. Words to the wise.
