I believe so, although I have a spray can of what claims to be 99+%
propan-2-ol that I use for head cleaning.

True story (although I am ashamed to admit it). I was sorting out a
Commodore 8250LP (slimline model, double sided drives). And I could not
get a reliable read signal.

I checked all the components in the head amplifier, the head switching
diodes, the head select signals, and so on. I then remembered to clean
the heads. Worked fine after that...
