I think you have the right idea, but you would do better to rotate through
three chains, or even four, instead of two. The idea is not only to clean
and lube the chains, but to make them wear together, along with the cogs.
Then replace all the chains and the cogs when they are really worn.
Chainrings don't wear very fast, comparitively, so you probably won't have
to touch them for a few cycles of chain changes.
