I have wood countertops that came from a former BBQ joint. Its all coated in what I believe is danish oil or another "food safe" oil to treat the wood.
My goal is to clean it, stain it black, then add likely around five coats of poly, since it will be in a commercial setting.
Should mineral spirits be the first step, removing whatever buildup is on the wood, or just go ahead and sand?
Am I wasting my time if I'm planning to use an oil-based stain, as in: just clean, dry, then stain?
