How does everyone keep their silkies clean when it rains?
Don't let them out in the rain!

Seriously though, Mine have gone out plenty of times in the rain, especially my Roo when he's out with the bigger girls because I like to give the silkie hens a break from him every once in a while. And to be honest, I don't do a thing to clean them up. I was so surprised the first time he went out in the rain, how beautiful he looked the next day. It's like he had gone to the groomer! He had dried off and preened himself so nicely that I don't mind him going out in the rain. I leave it for him to decide. I used to have a while silkie hen that did the same thing - went out in the rain and I couldn't believe what a mess she looked like, thought I'd never get her looking nice again. Went out the next morning to get her and clean her up - she looked better than ever! It was a nice shower for her!
