My friend puts ice cubes in his disposal every week or so to break up whatever might be down there still.

I dislike disposals. I never had one before now, but my apartment that I've been in since August has one. My condo that I will move into in June does not.

I compost my fruit and veggie scraps--since I live in an apartment, I freeze them and bring them to a friend's house for composting. Yeah, I'm a compost geek, and proud of it.
