Ann, I like the alcohol idea, too.
Sandy, I've been researching how to easily defrost a freezer online since I had never done it before. One site suggested wiping down the coils that make up the shelves with oil .. I am guessing the author meant "cooking oil" ... to avoid frost building up. I'm not sure how I feel about that idea ...
Both of you make this chore sound a whole lot easier than what I have read online
