So, in an earnest attempt to clean up my iBook G3 keyboard, I dampened a cloth with natural orange cleaner and went to town scrubbing they keys for the first time in forever. Not sure if some moisture got down in, or what happened, but now various important keys don't work. I've been making due with an external keyboard. Anybody know if there's an easy solution or if this is a huge, expensive fix? Ciao, thanks.
