Hi Charles, Smokey here
I'm in the process of teaching my 50th course here on Quadra Island.
I was looking at various items on your site today. And the last was the chain cleaning bit.
Please take some time to study Alex's Zero Friction Cycling site in Australia.
He's the man who's tested chains and lubes empirically for hundred of thousands of kms. He shows that famous lubes like Mac Off are total crap. He shows you how to remove the factory-applied grease. And finally how waxed chains save the life of the chain as well as all the other drive train components. Huge money savings!
Once you learn the technique, waxing saves time as well.

He will revolutionize your winter riding if you try wax.
Best wishes,
Smokey
