This is my procedure for mountain biking in dry, hardpacked, Southern CA conditions:

A major degreasing for me is to remove the chain, soak/clean the chain with a citrus cleaner or Simple Green, rinse in a bucket of warm water, and allowed to dry in the sun. I may do this once every three months.

I use Pro-Link "dry" chain lube and apply a drop to each rivet. Although this may take a little more time, it does not waste lubricant. After every other ride (~40 miles), I'll use a stiff bristle brush to knock off the dust/dirt and reapply Pro-Link. I've also tried some wax based lubes (Pedro's Dry Ice and White Lightning), but didn't like them.
