How to get weed smell out without an ozone generator

Standard detailing and ozone machines often cause lung discomfort and seriously aggravate asthma. This makes it difficult to clear lingering pot and smoke odors from second-hand cars, travel trailers, and houses. Even after sealing major surfaces with shellac, the smell can still seep out of small spaces like light switches and electrical outlets.
