This just happened to me. I got some vodka that I was cleaning a bowl on the outside of a Savinelli Tundra Canadian 802 and it took the shellac coating off in places. I ended up scrubbing it all with the same, dulling the surface and then rubbing it all down with the maroon scotch brite pads that I think are equivalent to about 600 grit sandpaper until it was a lighter brown and no shine. I then applied some Tried and True Varnish Oil that I have used for crafting a replica flintlock rifle stock. It is made of linseed oil and natural resins from pines. Purely non-toxic and no petroleum distillates. You can eat it or cook french fries it in if you really wanted to....I have one coat on now and it looks so amazing that I may purposely remove the finish and treat it this way for all my smooth Savinellis. I still don't know why pipe makers use dyes and toxic stains on pipes and then try to coat them with shellac or similar. This looks way better. A true hand rubbed oil stain. After 3 coats, I will finish with a final coat of the Tried and True original, which does contain beeswax and that will offer a final coat of slight shine and water protection. This will need to be re-applied every few years unless I just let the pipe patina. As of yesterday, I thought my pipe was ruined, but it is now improved!
