Some time ago I hand buffed the finish with a non-silicone wax. There is white wax residue left in the grain of the finish. Before putting it in the case several months ago I went over it with a soft bristle toothbrush and a little bit of lemon oil. That seemed to take the wax residue off at the time. However, the wax residue is still there. So at this point, is there something I can use to get rid of the wax or should I break out the sanding sponge and refinish with Tung Oil ( I have a can of Behr Pure Tung Oil) or some type of stain? Or stain and then seal with the Tung Oil? Suggestions?
