Why do I need to clean my black tank (or gray tank for that matter). I don't intend to eat or drink out of it and next time I use it I'm just going to **** in it again.

I always wonder the same thing.

Kinda goes along the same lines as never putting toilet paper in it, to never doing #2 in it, to never using it. To each his own, but that's just weird.
