Lets not get off on a tangent about WD-40 as a contact cleaner. Its not advisable to use, especially as a tuner cleaner.

Just watch the silicone lubricants - most organic polymers aren't compatible with silicone - early plastics don't like silicone at all. Silicone will also destroy the butyl rubber elastic strip often used to keep ferrite tuning slugs snug in adjustable coils. As Andy mentioned, a good cleaning with Deoxit or denatured alcohol (in a pinch) to start, then sparingly apply tuner grease. (If you can still find it!) PTS made the best stuff, their green grease. Second choice would be General Cement's TunerLube - again, if you can find it.
My two cents, based on over 20 years experience:
NO: WD-40 (my reason: it attracts more dirt and dust), Tuner Cleaning Foam Inserts (they fall apart, thank God they are gone!), Blue Shower - remeber that stuff, anyone? I had a Magnavox tuner that was destroyed by that stuff.
MAYBE: Silicone (okay on Delrin and other modern polymers used in modern tuners)
YES: Deoxit (oleic acid based), some alcohols, Tuner Grease - a little goes a long way.
Anybody ever seen an MSDS for Tuner Grease, or GC's TunerLube?
