We just bought a new oven. The guy in the store told us we could just put it on our refrigerator. Guess that wasn't a good idea after all. Now there's a spot on the refrigerator that smells really bad (like cheese). It seems like it started to melt, but the inside of the freezer (on the top of our refrigerator, there's a freezer) there's no damage at all. It's been a few days now, and we thought the smell would go away, but nope... Still there! How do we get rid of this?
