I recall reading somewhere that some brand/s of scanning fluid is 10% mineral oil and 90% Naptha. I have used light mineral oil in the past but it is a pain to clean. Used mild dishwashing detergent, cotton balls and running water.
Today while cleaning some items with "Ronsonol" lighter fluid I noticed that it was Naptha and it evaperated fast with no visable residue.

If I were not leaving, in a few days, for a month photo shoot I would try it myself, on some backup negs, as I think it may be worth the try.
