My typical riding is VC style at 15-20 mph, all pavement. The only time my bike sees dirt is when I ride with my daughter to/from school and I hose down the bike before the next ride to get rid of the sand from the chain.

Looks like you found your problem.
Any moisture that gets in there stays. Even if you don't ride much in the wet.
