Re: arsclist cleaning and demagnetizing tapes
Doug and all,
I have always been warned that the other 9% of the 91% isopropyl alcohol is
water and other things to be avoided. I have found that out here in Los
Angeles, Savon can get 99% isopropyl alcohol, but it is expensive at aboUT
$10/pt. I think you can also get it in gallons from Grainger or other
industrial supply outlets for less. The best bargain, however, if you ever
drive to Canada (you can't bring this with you on an airplane) is that at
least Shoppers Drug Mart has it for about $2 CDN / pt!
I stock up on my drives to Canada <smile>.
Years ago, for quadruplex videotape recorders, a major network in NY had
piped-in Freon piped into each tape cubicle! Until the environmental
concerns were understood, I always used to use Freon for head cleaning,
alcohol for rubber cleaning.
What is the best thing to use on rubber pinch rollers?

Isopropol alcohol won't hurt, but many of the consumer
preparations ("rubbing alcohol") also contain perfume
and other additives which your tape heads don't need.
Check the list of ingredients. Look for the label that says
"91% Isopropyl Alcohol by volume".
Or, you could buy a preparation made specifically for cleaning
tape heads. You can get it from pro audio/viedeo dealers.
Ampex used to make it in a small can, and now another company
makes the same product, also in a samll can.
I get it from Burlington Audio/Video, Inc. in Oceanside, NY.
(516) 678-4414. Called Head Cleaner, they sell it under the
Burlington brand. It contains Trichlorotrifluroethane.
Good luck. And don't inhale the fumes!
