I've found that the best way to clean a box is to first flood it, and then get a strong and very flexible scrubber in to every nook & cranny to throughly clean it all out. It's quite an arduous process, and usually involves lots of heavy breathing and what sounds like praying.

But well worth it.

Complete surrender should not just come at moments in which one faces overwhelming odds, but in the calm when it seems one is personally in complete control of one's life.
