This is my first year for cold weather commuting and it's going great, but I have an unexpected problem. When I get to work I change from cycling clothing to civies and hang my wet gear behind my office door. I've noticed an occasional whiff of wet wool (jersey is merino). So far none of my colleagues have noticed (or said anything) but I'm pretty sensitive to keeping the environment clean. Short of burning candles or getting some kind of air filter I'm at a loss. Any clever ideas?
