After removing some of the worst dings with a damp cloth and a fairly hot steam iron, I use pure, unadulterated linseed oilicon, rubbing hard with a cloth on a cork sanding block. If there´s anything that does not come off, I use very fine pumice dust, mixed in with the oil and just rub hard. After several hours a day, and in just a few weeks, I guarantee that the finished stock will pass inspection.
