That's why I use Soylent Blue.
It's the full-body shampoo made from people, and boy, does it keep my fur shiny and smelling its best. It also keeps that pesky dandruff from popping up in places you don't want flaking, and the ladies love a space pirate who can spend all day wallowing in gore and still come out smelling like a Arellian Swamp-Rose.
So try Soylent Blue, it makes people clean, because it's made from clean people.
