Question
Hello! I just recently picked up a bookshelf from an antiques store. After my purchase I discovered, on the bottom of the shelf, the wood is black on one corner. I'm not sure if this is mold or mildew or if it could be something else. It's inside the wood (the wood itself is black, not coated with a black substance). If this is mold or mildew should I get rid of it or is there something I can do? Is there a possibility it may be something else? I haven't brought it into my home yet because I'm not sure if it's something that is likely to spread? I really love this piece of furniture so if there's something I can do I'll do it. I just don't want to spread mold or mildew into my home. I really do appreciate your time. Thanks in advance, Lindsey

Answer
Hi Lindsey
Nice to hear from you.
If the wood is black and it cannot be rubbed off, this is not a problem
Mold can only live in damp conditions. There is no danger in bringing the piece into your home.
Its my experience that most of these black marks are old India ink spills.
Nothing wrong with giving the entire piece a nice cleaning with a rag dipped in mineral spirits followed by a waxing.
Great question
Regards
