Re: WD-40
It will actually be dissolved by most non-polar solvents. It is a wax. It gets harder as the lighter fractions slowly evaporate with time, AFAIK it doesn't actually harden like linseed oil or teak oil.
However, using silicone spray instead may not be a good idea because the stuff can penetrate into weak electrical pressure contacts and cause intermittents.
