Thee very best method is to first finish sand the stock. Then brew strong tea...about 5 teabags in one cup then apply it to the stock. The stock is then placed in an enclosed container with a viewing window (plastic or glass). You then use commercial ammonmia (26-28%). You do NOT do this inside as it will set you free. When you like the color, stop. Expect 4-12 hours.
By the way, you put some of the commercial ammonia in a small tin...like a tuna fish can tin and the fumes do the rest. It is the best method I have ever seen.
