I just wanted to say thanks to the forum members for their contributions. I had a new Savoy Grabow that was ailing with spots on the lacquer. I forget the actual post which mentioned using acetone to remove finish on a pipe,and I used it. It removed the clear coat lacquer without disturbing the stain. Using cotton balls and q-tips, it worked like a dream.Polished with pipe polish afterwards. Feels as though, I have a favorite back in perfect working order.It smokes cool to the touch now. Thanks to all.
