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.

The makers of WD40 might disagree with you.

Good luck with it, you could do worse.

Indeed. WE40 may be the perfect cure for every problem - but it IS a
good general-purpose cleaner/lubricant/anti-corrosion fluid. I've never
had any problems with it.
