Yes, I had a can of that Freon cleaner, and it works great on tape heads -- so presumably
floppy heads too since they have the same requirements.
Back in college I once helped clean 1311 disk drive heads, after a hydraulic system leak.
That was done with isopropyl alcohol. High purity in that particular case since it was
available at the chemistry department store room, but I would expect ordinary store bought
90%+ would work fine. You'll want to use some sort of lint free applicators.

If alcohol isn't a good idea, white vinegar
or dilute ammonia could also work. Ammonia is the world's best peneyrant as far as
I'm concerned. But to get into deep crevaces and crannies it needs time. Sometimes 24
- 48 hours. It will remove somenpaint lickity split.
The traditional stuff
pre-Montreal Accords was usually Freon TF or
similar chloroflourocarbon with perhaps some isopropanol mixed in. At
least that's what my big bottle of Xerox floppy cleaning liquid claims.
I suspect that some type of ether may also be suitable. I've largely
taken to cleaning tape heads with heptane--doesn't seem to bother
plastics any.
