You won't like the solution if you like your White Lightning, but try using oil for lubing the chain. Wax-based lubes (like WL) fall off the outside of the chain -- that's why they're so clean -- but that means you've got bare metal touching the air. The film an oil (or "wet") lube leaves on a chain protects the chain from rust. You can wipe it down until it's almost dry, and what's left will still protect the chain, and hopefully won't attract too much dust.
