That's one reason chrome stays were popular on high-end bikes, and the last bit of chrome to be phased out was the right chainstay. Even if you meticulously use the chain-hanging peg on the right seatstay, there are many occasions during which the chain will be dragged across or banged against the right chainstay. Your chemistry idea makes sense, as well.
I can't help you with your left-versus-right crank observation, unless you have a prevailing salt-spray wind, as I do, and always store your bike in a particular orientation.
