As I said, I agree that WD-40 has no business being anywhere near a piano 
action, but it is a petroleum derivative, containing no chlorofluorocarbons 
or silicone. None - according to what's printed on the can. And while being 
entirely different stuff, neither WD-40 nor silicone are hygroscopic and 
there is no evidence that I've ever heard of that silicone gums up actions.
