My IWC watch box, which I got when I bought my IWC secondhand, is made of a black, rubber type material. It's turning into a soft sticky mess. Unfortunately I don't have the outer box, so that leaves it open to the environment to collect fuzz, dog hair, etc. Is there something I can treat it with to keep it from degrading? IWC doesn't give away their watch boxes, so I'd like to keep it in relatively good shape. Several of my other watch box internals have basically fallen apart. They're now stored in a climate controlled safe, but I don't know how people stored them before I got them.
