Lemonade isn't all that good for keyboards either. After it begins to dry, all I could type was aaaaaaaa, 555555555 and 222222222222222222222222222222222. I found that black coffee does little damage in the long run,except for being a pain to clean between the keys, but large amounts of water tend to short out the cordless phone on the desktop. I suggest waiting until liquids dry before dropping the sesame seeds from your bagel all over the keyboard.
