CAPTDON, if you can find GT-85 anywhere, it is your friend. It contains PTFE which repells dirt, salt, and all sorts of other crap. I clean my wheels with it once a month about. In between cleanings the dirt/lube/brake dust can be sprayed off with a garden hose.

if you can't find it, go to a local bicycle shop and ask them to order you some. They can get it from Quality.(a distributor)
