I inherited a Coats thread cabinet from my Grandmother's estate and finally got it home. I think it would be great for storing small machinist's tools, but it will make its way inside the house and be fancy once I figure out how to remove the musty smell. The bottom drawer has, in pencil, 'B Bros Feb 10th 1882 ' which I assume is the mfg date. The sides and top are 16.5" wide lumber (one side is, unfortunately, badly cracked). The top has some scratches. The front has 1/8 or 3/16" veneers that are really pretty in-person. The rear is the best part, I think. It's got a big, colorfully painted ad for Coats' Thread.
How can I safely treat the musty smell without damaging the cabinet's value?
