Boeshield T-9 was developed by the Boeing Company for lubrication and protection of aircraft components. It is a combination of solvents, lubricants, and waxes designed for penetration, moisture displacement, lubrication and protection. Boeshield T-9 dries to a thin waxy film that clings to metal for months. These properties make it ideal for bicycle chains, particularly in wet environments. Boeing also successfully tested T-9 in marine saltwater environments, and it protected against corrosion caused by the salt. If you ride on the beach or near the sea frequently, T-9 is likely the best choice short of manufacturing every piece from titanium. It will also loosen rusty and corroded parts and is safe on paints, plastics, and vinyls. 12oz. aerosol can.

This was recommened to me by my LBS. It's an excellent solution and it keeps my chain looking clean and running great. I've used it two ways:
Lube your chain then clean it immediately with a rag to get a lot of grime out.
Lube your chain the night before and let it dry, then run it through a rag in the morning.
It is also sold in a liquid form that you can drip on your chain and refill when empty. I prefer it over the aerosol, hence 4 stars.
This stuff works well but it tends to accumulate on the derailleur cogs. Also you should as with all lubes, put it on the night before so it dries. Otherwise, you will accumulate a lot of unnecessary dirt and grime and probably have grease marks on your legs. Not pretty. Can we last you a long time. Over a year riding 4 days a week cleaning after every ride.
