I've been using a teflon dry-lube product, not specifically made for bike 
chains, with similar results. It sprays on wet, and then the vehicle 
evaporates, leaving a teflon powdery dry-coat which seems to repel dirt. And, 
as it's sprayed on, the vehicle carries the Teflon into the rollers and 
hidden places. I haven't heard a skweek or seen rusty chain in a while, and 
it's super-humid here!
