We used the top of our refrigerator for overflow storage - the waffle iron lived there, along with a couple of other things. And it was just barely above eye-level, so I did kind of see it sometime. I really noticed it when I was getting something down from it. It probably got cleaned once or twice a year.

Admittedly, her cleaning solution wouldn't really work for my situation - the plastic wrap on the refrigerator would be too slippery to put things on!
