This works.....be careful of the fumes.....: You need: Air tight container large enough to contain a mesh grill, holster and about 1/4" of household ammonia in bottom of container. Pour in ammonia, put grill in place, place holster on grill, seal container, place in sunlight for 8 hours. Take out the holster and smell of it. Still smell cigarette smoke? .... Do over one time using fresh ammonia. Caution, some holster threading might be weakened by the ammonia. Very low likelihood of that happening.

The ammonia fumes absorb all sorts of odors and isolate the odor which then becomes dust and falls out of the air. Works great in rooms with bad odors. Just use more trays of ammonia. ...........
