I'm aware of the normal causes of rust. Ive heard about cell rot. But I have another issue that seems to be tied to an antique razor box. Every razor that goes into this case ends up with rust on it. The inside of the box seems to be made of wood with a red felt lining. The lining is kind of degraded and not in the best shape. Is there anything that is similar to cell rot that is chemically altering the razors in this box? For the record, the box is completely dry, no dampness at all. And I always throw several packs of silica gel in mu boxes anyway. I have two other boxes just like it that don't have this problem. Any ideas as to what could be causing this?
