Clean Mac Keyboard

My Mac's keyboard was a mess.  Accumulated fingerprint boogers left brown residue on most of the keys.  This YouTube video shows a nice solution (pun intended), using a Tide To Go stick to moisten each key, wait 10-15 seconds, then wipe them off.  I removed the batteries first to avoid any shocking moments.  Probably would work on any keyboard, but haven't tested any.
