washing a yarn fursuit?

There's a company called Fuzumi that makes things made from some type of crocheted fur like yarn.

My mate has an entire suit made from it. Head and all. I'd like to be able to help them wash it, but I'm very worried and have no idea how you would go about washing the bodysuit.
Personally I hate the yarn, it gets everywhere fast and you barely have to pet it. I know that if I wash it with normal methods, it will easily leave bald spots.

How can I safely wash everything without losing to much of the yarn?
