I see the tape sticking to posts syndrome in my limited experience with HP QIC tapes also
(DC100 / DC2000). The best I have come up with is wipe the posts with isopropanol. But I
had not thought of lubricating them for a 1 time read, interesting idea. Or replacing the
posts with ones machined from Teflon or Delrin?

I'm a bit surprised that this is even a "thing" in the audio business.
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?
