Back in the day there was "Tape Head Cleaner" Which was a little tin
of trichlorotrifluoroethane (a.k.a. Freon 113) where you screwed the
cap off and it had a rod with a fluffy ball on the end inside, and you
would slather that all over the heads of 9-track tape drives etc. It
evaporated almost instantly. Of course after evaporating it floated up
and destroyed the ozone layer, so probably not super obtainable these
days.

A search for "Tape Head Cleaner" suggests there are similar modern
formulations used for HiFi equipment etc. that might be applicable.
