What is the best way of removing the manufacturer ink stamps off of my new wood?
Lumber-grading stamps are nearly impossible to remove from the surface of new wood. The only way to remove these enduring marks is by sanding. Use a 10,000 rpm orbital sander starting with 40 grit paper and finishing with 80 to 100 grit paper. Caution: 140 grit sand paper will produce a finish too fine for the wood sealer to penetrate. Do not sand rough sawed lumber. Note: you cannot sand wet wood.
