[QuadList] QuadList Digest, Vol 42, Issue 47

There were also a number of stories out there that Ampex Head Cleaner would dissolve the glue used on  Betacam Head tips; at least on early Betacam VTR's.  Any confirmations on that?

The old Ampex head cleaner was a mixture of Xylene and freon.  At an Ampex maintenance school for D2 machines, they told us they used Xylene because it was the only thing effective at dissolving the tape binder that deposited on the machines.  Many years ago, I worked at an automated FM station where we used xylene to make clear windows in audio tape to allow optical cuing of the spot reel.  My guess would be you would not want to use xylene directly on tape because it will attack and soften, if not remove completely, the binder.

Thanks for all the good information.

I have to agree about Xylene. A little aggressive for my tastes for cleaning glue, unless I get to a really bad spot.  However, I do use it exclusively when cleaning transports.

To clean off the glue, I use alcohol and a Q-tip. It takes some time but will get the glue off. I then clean the tape with multiple passes with Pellon cloth and clean the machine after each pass since the guides scrape off any remaining glue.

Goof Off and Goo Gone may work too. But I must try the Eucalyptus. Sounds like a great solution. I will have at least 20 more reels to clean.

Best,
Park
