We've had a ceiling leakage from bath above it upstairs. It leaked into a small closet we have downstairs. The carpet got all wet etc. The room was aired and all dried up, we've also just had the ceiling all newly replastered. But the smell of damp still lingers in the closet and it's now clinging to all the coats hanging in there. Short of changing the carpet (which has long dried out) is there anything we do to get rid of the smell?
