True for the most part, but please do not place
the common Freon TF in that
category when magnetic media is involved. 15 years ago at the tv station,
I got tired of paying for Freon-TF by the gallon, and cleaning the heads on
all our VCR's 2-4x daily, and tried cleaning one with paint thinner alcohol
from ACE Hardware. I didn't have to clean it again for a week! So I
switched cleaning agents on the spot. And it turned out that Freon-TF was
also much harder on the elastomer parts like pinch rollers. I cut the time
spent cleaning heads and rollers by 90%. Roller replacements went way down
too.
True. I've never seen Freon being used for head cleaning except on
the old 2" video machines where it coud be sprayed on the moving
tape (even on-air in some cases) just before the rotating head.
For everything else alcohol was used.
