I've never been able to find 91% isopropyl alcohol, but I've discovered
that drugstores which supply doctor's offices (often located in the same
building as one or more doctor's offices) may carry 99% isopropyl.
Anyway, this is fine stuff for cleaning heads and capstan, but NOT the
pinch roller.  Alcohol will cause the rubber to harden eventually.  The
manual for my tape deck (Harman/Kardon) suggests using an "aromatic
hydrocarbon" for the pinch roller.  Someone suggested that ordinary lacquer
thinner was good for this.
