 $15 for 125mL.  Sounds like that would be good for hundreds of disks. 
I've mentioned it multiple times on VCF and it's also mentioned on Herb
Johnson's retrocomputing web site.
I can't risk clobbering a client's disk or tape, particularly not one
sent by an institution's achivist of whom I'd like to remain on the good
side.  D5/Cyclo has been a lifesaver.  The stuff is slick but inert;
it's used extensively in cosmetics and lotions.  It's also somewhat
volatile, so it evaporates after awhile.
Hair detangler is a very notable use of it that even finds use in equine
circles.  I suspect that you could drink the stuff and not suffer
anything but a bad stomach ache, but I'm not about to prove it.
Another bottle of stuff that I keep around for softening rubber pinch
rollers and capstans is methyl salicylate/oil of wintergreen.  Smells to
high heaven like arthritis cream.  Mixed with a mild solvent (e.g.
xylene) it softens hard rubber up quite nicely, but your shop smells
like a gym locker room for a time.
And of course, heptane for cleaning--dissolves glue, cleans tape heads,
etc. without harming plastics or staining paper.
FWIW,
