Cleaning an IMA Nepal "yak fat special?"

[5thDragoons]

I've got the itch to try another one. I did 5 or 6 several years ago... still have 3 of them: 2 Sniders and a Gahendra. I see now they have 1837 Brunswicks on sale with free shipping.

I'm up to speed with cleaning the metal - spray oven cleaner or a strong solvent to remove the yak fat. Any suggestions for getting accumulated crud off the stock? Norm Sutton used to be the yak fat cleaning guru, but I can't find his articles anywhere. I *think* he used Ace Hardware paint stripper on the wood, but can't locate confirmation.

ETA: I got in the backdoor of British Military firearms and found an article on cleaning the stock. Norm did use paint stripper - others tried a wide variety of solvents, including straight lye. I have a supply of lye on hand for plugged drains but am leery of using it on wood. SW
