You all may have already heard to do this, but I think it is GENIUS! (I just read it, somewhere - can't remember where, today.)
To make refrigerator cleaning day not so awful, all you have to do is line (cleaned) refrigerator shelves with Press N Seal. When cleaning day comes, empty shelves, pull off dirty Press N Seal, and replace with a new sheet. It. Is. Genius!
Whoever thought of that is my hero.
