In the QuadList thread about Foam Tape Reel Flanges last Dec., you might recall this portion of that post:

In a separate thread about powdery substances, videotape restoration facility Spec Brothers' Peter Brothers went into the history of the problem:

The cushion-flange glue problem only happened on 3M (Scotch) 1" and 2"
video.  

Most cushioned reels are fine but, at one point, 3M subcontracted out 
the cushion attachment part of the reel manufacture and the
subcontractor used the wrong glue. 

3M devised a process for addressing the problem, and Jim Lindner's Vidipax (since sold/demised) acquired the info on the process and used it.

Linder also reported on the use of Eucalyptus Oil at Screensound (the national archives) in Australia:

Be careful, whatever you use.
