BLEACH: Why "BLEACH"?

What's in a name? Well, for most anime series, especially those that come from light novels, the general idea or main premise of the series is introduced in its title. One Piece is about Monkey D. Luffy's quest to find the legendary titular treasure; Dragon Ball, despite having developed far beyond, is about the magical wish-granting orbs – also titular. My Girlfriend and My Childhood Friend Fight Too Much is about... well, that.
