Query: Smells like mothballs

I bought this stand to keep our bikes upright in the guest bedroom. Stand is solid (though kind of a pain to put together), but otherwise great. A few days after we got it in there, we noticed a weird smell in the bedroom. Turned out it was the rubber feet of the stand. They have a very strong motor oil and mothball odor to them. I took them off, washed them, and let them air out. After a month outside they still smell horrible. Now, the stand slides around when I put the bikes in, but it's too big of a PITA to send it back.
