Zinn and the Art of MTB maintenance.

This is what I would do, and do do after rides in our sandy soil, when it's wet and muddy out. Muddy sand? sandy mud?

Hose everything off.. do not use a pressure sprayer. Then, I use the chain cleaner tool thingy on the chain, and I go over the cassette carefully with a rag in between each cog. Re-lube. I don't take the whole thing apart.
