I've been using the stuff in the link below for years on bicycle and motorcycle chains. It's very thin going on and flushes a lot of debris out of the links, then dries almost to a wax. Once dry, it stays put and is nearly dry to the touch. A can should last several seasons.

Use it in a ventilated space, because it gives me an instant organic solvent headache until it is dry. YMMV.
