Sir:
I think that's nitric acid.
Get nitric acid and mix it 10 to 1 with water. Whisker your M.L. stock good and apply (use gloves!) - then with the wifes hair dryer (or torch) heat the stock - it will turn pink- don't burn it)
Then use potassium permanganate (it will make a bomb like reaction with the nitric in the open - not on the stock) and soak the stock - it"ll turn deep brown/black.
Neutralize it with soda water and let totally dry.
Then take linseed oil and fine steel wool and work it out until the stripes just show - let the linseed neutralize and then use Tru-Oil. Works great.
