Hi FOTMD! I recently drove up to Connecticut to acquire a well-loved and well-played McSpadden—all cherry wood as far as I can tell, M12CC, Nov 1999, George Looney signature. The dulcimer belonged to a man who recently passed away at 100, so I'm not sure how much use it got over the last few years, or if it was mostly in its soft case.

Both the case and the dulcimer smell pretty strongly of dog (there was lots of dog hair in the case, I've vacuumed it/lint rolled it as best I can). Do you have any tips on how to safely deodorize them? Charcoal? Baking soda? Air and time? 

Pic of the McSpadden attached, as well as the McSpadden next to my cardboard beauty and the custom 5-string Grant Olson dulcimer I acquired a few months back.
