Restorers have been baking audio tapes for a long time.
That is acknowledged in the slides, isn't it?

Isopropanol does not clean the sticky deposits from
equipment--you must
use a stronger solvent. Acetone, Perc or MEK generally does the trick.
I am trying to read a bunch of late 80s QIC-24 tapes (Sun/Computervision
install media). In addition to the normal QIC band problem, I am seeing
problems with the tape sticking on the metal posts that the tape goes
around to change direction towards the reels. Should I try wiping the
posts with acetone or wiping the tape with cyclomethicone? Should I be
baking the tapes? If so, what is a safe way to bake QIC cartridges?
