I just traded for a very nice Fox Sterlingworth 12 gauge. Great little gun, has a little bit of collector value. Not much. The clear finish, shellac, has been added to over the years. It is quite dirty in several places. I can tell it has been added to by the drip marks in certain areas. I am going to clean off The older shellac finish and replace it with a nice amber shellac. Cleaning off of the flat wood is not the problem. I know how to do that. But there is an accumulation of shellac in the checkering that I don’t really know how to remove. I do not intend to re-cut the checkering no matter it’s condition. I will live with it the way it is even if the checkering is somewhat rounded. But I would like to remove the excess shellac. I have tried using my solvent to loosen it with a soft bristle brush. But that just seems to move it from one place to another. Does anyone have a suggestion on how I can remove the excess from within the checkering.
