If your chain is rusted you are better off buying a new chain. If you just want to clean it; remove from the bike, soak in minereal spirits for an hour. Wipe clean.
Repeat if needed. Allow to dry, re-install, lube with a good chain lube, (not WD40).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
