Jack, Thanks a ton for the update. The acid is the most important compound, and I would suppose the Naptha cleans off the oxidants once the chemistry has done its job. I should make my own given how cheaply the contents can be acquired.

Internet lore claims the 5% "trade secret" portion is largely linoleic acid (from flax seed). GC Electronics has a much less expensive similar product called "DE-OX-ID" which is 60% Aliphatic Hydrocarbon, 35% Kerosene with the remaining 5% being more hydrocarbon solvents according to its MSDS. It's what I use. Naptha is light end hydrocarbon, with both linear and aliphatic chains. Lighter fluid is mostly naptha by the way. Last bottle of DE-OX-ID I bought cost about $6 for 2 oz in a brush applicator cap bottle. It's gone up a couple bucks since then, and there may be a problem with additional shipping surcharges since it's flammable. (Earlier this year, I was charged $10 to ship a 2 oz bottle of red Glyptol varnish for that reason.) Jack K8ZOA On 6/17/2013 7:02 PM, Bill K9YEQ wrote: > Don, > > Nice suggestion.
