Just smash the dirt off with the water blaster !
No I usually alternate between acetone and turps.
The acetone slowly melts the dried on gun oil from the stock and the turps draws it out.
But this stock has no oil staining at all and just a few light gun cabinet bruises.
That's a first ever for me and it needed a different treatment.
So I just used turps and OOOO steel wool to scrub off some old gun safe mildew marks and turps and a tooth brush on the checkering.
For the first time ever in my experience there was not the slightest trace of crap to come out of the checkering !
The mildew marks came out nicely.
Then mostly the stock oil I applied slowly ran off the bottom of the stock and fore end when I hung them up.
The walnut is so dense, so dark and so well oiled and sealed originally that the pores are still filled and closed and it just won't take any more oil.
The grain in the butt stock is now more clearly visible and I will try and get some decent images outdoors soon
