I find that
perchloroethylene works to get stubborn tape-head deposits
cleaned up. Can be found in some formulations of brake cleaner as well
as the usual dry-cleaning solvent. Nonflammable, but somewhat toxic,
so use in a well-ventilated area. Not really plastic-safe, so use
sparingly. Also makes a great solder flux remover from PCBs.

the head where the tape
touches the head. Any ideas?
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.
