I don't know what a laboratory supply house would be able to do for you.
I've bought some hexane that way and since it was a listed chemical,
shipping was as much as the litre...ran me $100 or so to get it here.
However, my solvent of choice is naphtha. I currently purchase it as
"Ronsonol" brand lighter fluid, but Ronson has been bought out by Zippo
and in talking to the folks at the Zippo "shrine" in Pennsylvania last
summer, they think they will substitute Zippo fuel for Ronsonol, but did
not have a timetable.
It turns out at http://en.wikipedia.org/wiki/Coleman_fuel that naphtha
is a combination of various short-chain hydrocarbon molecules, so hexane
should be similar (I have not run extensive tests) as it is one of the
components of naphtha.
in your browse after contacting your representative if you are in the USA.
IPA is no where near as effective as naphtha (or hexane) for removing
the gunk buildup from sticky shed tapes.
HOWEVER, please note that ALL of these substances are highly flammable
(including IPA) and many/most/all may be hazardous to your health.
Please read the MSDS prior to any application.
What works for me may not work for you and may not be in compliance with

I have been asking around all pharmacies, chemists etc. in Cambridge with the same answer: its a restricted substance which cannot be sold without a license... Does anyone in the UK have a tip to where to get a hold on, lets say a 100ml flask?

The easiest would be to stick to one of the latter, but I am looking for the professional solution and don't want to make compromises. Moreover, a number of tapes in the collection are dirty and I suspect that a number of them will be shedding, so I expect to be doing a lot of cleaning.
