After working with the user on a tape-drive cleaning issue, the tech suggested that she get a can of compressed air and blow out the drive. The user called back in tears. She said she "sprayed the inside of the unit with WD-40" instead of air. When questioned about how much she sprayed, her response was, 'I'm not sure. While I was spraying I realized the can didn't get cold, so I looked to see what was wrong."
