I have searched for past threads, but can't seem to find what I am looking for. I am meticulous in cleaning my bike after every ride. The one task that is a pain in the butt is cleaning the cogs. I have the usual cog plastic, curved cleaning devices, etc. Heretofore, I had been spraying chain cleaner on the cogs, and hosing them down, but I just read (I believe in Zinn's maintenance book), that the solvent can easily find its way to wheel bearing grease which of course it destroys.
Does anyone have some great method (without cog removal) for making the cogs and spaces in between look as shiny clean as my chain?
