I just moved into a new apartment about a month ago, and I have a garbage disposal in the kitchen. I've never had one before so I honestly don't use it much. I've never put grease or meat in it, just random food scraps. I walked in the door after church this morning and my whole apartment smelled FOUL I tracked down the smell right over the garbage disposal...now what do I do? Is there something I can put down there to freshen things up a bit? Please help because this just won't do!
