Hi, Doug (and list),
Just a few miscellaneous thoughts:
(1) Ronsonol lighter fluid is pure naphtha but Ronson has been bought
out by Zippo and I don't think that Zippo lighter fluid is the same--I'm
not certain. When I found that out, I bought several containers of
Ronson lighter fluid.
(2) Naphtha itself is made of other chemicals that are available. For
those who wish to wade through it, there is an article that seems to
cover the wide range of the use of the term Naphtha.
The most interesting item there is a link to the Shell-manufactured
The CAS number for the 95% component is 64742-89-8 which is listed on
page 485 of the "Handbook of Green Chemicals"
shows that the same CAS number is applied to both Naphtha, light
alphatic AND Heptane (C7).
I did not research 64742-88-7 which is 5% but it appears to be a heavier
chemical, referred to as medium alpha.
(3) Hexane (C6) is an often-recommended solvent and one that is
suggested for cleaning pinch rollers by one of the major Nakamichi
repair shops (the one in Connecticut). I don't know the difference
between C6 and C7 (these numbers should all be subscripts, but HTML is
not generally recommended for mailing lists)
(4) One interesting chemical is Jojoba Oil and it's often available at
Trader Joe's. It is considered one of the closest replacements for Sperm
Whale Oil and was considered at one point for magnetic tape lubrication.
(I have had better luck with D5 than Jojoba for re-lubrication), but it
might be a substitute for nose grease--it should be investigated.
