the unthinkable happened... someone spilled rootbeer on my mbp keyboard. i quickly turned it off and disconnected the battery.i turned it upside down and sponged as much of it as i could. later when i turned it back on everything in the comp seemed to work fine except a stickey space bar. no problem i thought, when i brought it into the mac store the "genius" told me that i would have to replace the entire keyboard for $800 in order to do anything about this single stickey key. when i told her that that was ridiculous she continued to tell me that if i do not get it replaced that mold could grow and eventually ruin my computer? is this something i rely have to worry about, or was she just trained to say that so apple makes more money off of repairs? as you can see i am still typing just fine so i do not. feel like 800 dollars is worth it for something i may or may not need. is there any ideas to where i could get it cleaned or do i even need to? any input would be doing me a great favor. i just got the comp less than a month ago so for me to spend almost another thousand would be hard to do.
