Maybe talc the back of the neck before playing.

FWIW Talc is a very fine (both meanings) polish. It is an abrasive, but on (say) shellac varnish it would act like polish.

Just a thought but talc without too much perfume?

There used to be a glass cleaner/polish that was the same pinky colour but came in a liquid medium and probably was talc in water. In a glass bottle vaguely oval in cross-section. It dried fairly quickly to a powder as fine as talc (a bit like calamine lotion). I have the name Glit on my mind.

Anyone remember it?
