So I have a humidor my siser in law bought me a while ago. It's not a very high end one, but it's sentimental to me, because she engraved it and gave it to me for Christmas a few years ago. And it actually has a good seal. My problem is, when I first got into cigars I didn't know much, and apparently I didn't check on my cigars often enough, and there was a puddle on the bottom of the humi, of which the cigars that were over it got mold. Now I haven't been using this humi since then (probably 2 years ago), I've just been storing accessories in it. My question is, after all this time, is it safe to use as a humidor again? I don't want to risk mold outbreak, and I've sanded the spot lightly in the past, but there's still a "spot" on the wood from where the water was laying.
