I am a firefighter and found an antique dress form in a burned out building. I took it home and it smelled badly of smoke as you can imagine. Somebody suggested a mixture of water and ammonia in a spray bottle. I sprayed it down once each day for several days then let it air dry. It worked great. This antique smells clean and new - not even a smell of ammonia. Sorry, but I don't remember what ratio I mixed it at.
