[Milsurplus] Contact Cleaner WD-40

[Glenn Little]

WD-40 is NOT a contact cleaner.
It displaces water.
It leaves a gummy residue when the solvents dry out.
It does NOT lubricate.

Use a proper contact cleaner to clean contacts.

When used properly Deoxit is a very good cleaner.
It will swell up phenolic switches if not properly applied.
