A few things on WD-40.

Its name means Water Displacement - 40th try.
It is, essentially, stoddard solvent, that is highly refined kerosene and a very small amount of very light mineral oil.
It is 100% volatile over time. Which is directly related to temperature.
Most gunks and goos are soluble in WD-40. But, what is not rinsed away will be evenly distributed when the solvent evaporates. So beware!
It is a rather gentle solvent, and does not attack most plastics or finishes. *MOST*, not all!

WD-40 is NOT a contact cleaner. What it does along those lines is by rinsing.
WD-40 is not a lubricant. It will (temporarily) reconstitute some lubricants under some conditions.

Good luck with it, you could do worse.

Stoddard solvent is aka white spirit. I'd try 100 times rather than 10.
