It may be banned for manufacture and sale to "consumers", but existing
stock does exist (at a hefty price) at many local electronics stores.

I've been cleaning heads for decades using reagent-grade isopropyl alcohol.

Be wary of the "rubbing alcohol" you get at a local drugstore - the 80%
or 93% stuff may very well contain some oils.

There *are* some parts on tape drives that aren't supposed to be cleaned
with alcohol. Some rollers and vacuum column sensors fall into this category.
(Actually some of the vacuum column sensors aren't supposed to be cleaned
with anything ever...)
