Bill,
It'll go in the wash tonight. I think hot water and Dawn dishsoap should cut the oil/wax.
Should work. I got a terrific closeout buy on a Filson Shelter Cloth hunting jacket a few years ago. Like all Filson products, it was overbuilt, stiff, heavy and trapped sweat inside - but I knew that (having already learned the hard way), and the price was too good to resist. So I washed the jacket in hot water and detergent.
I think washing it got rid of 5 pounds of wax and gunk, turning it into a breathable, wearable, practical field jacket for late season grouse hunting.
Of course, it lost all its waterproofing - but I've become a fairweather hunter in my old age, anyway!
I still use a Filson game bag, but got rid of most of the Filson stuff I've had over the years. Jackets, vests, hats - they never wore out, because I learned not to wear them. Too @#$%! heavy for field use, IMHO.
