Strong odor coming from woodstove

It could be from animals nesting in your chimney, in which case there could be something dead causing the stink. It would need to be removed. In most fireplaces, heat from the fire would destroy most sources of odors, so I would start with the chimney.

Charcoal bricks non treated for quick starting will absorb orders. You do need to find the source. If you don’t have a chimney cap in place...you might want to get one.

If your using that stove daily, cleaning once a year is putting you at risk for a chimney fire.... its recommended to clean 2 - 3x a year depending on the quality of wood your using. Was it painted anytime this year? it could be that. or the critter in the stove pipe is a possibility if you don't have a screened chimney cap.

Stores like Tractor Supply sell something called PDZ which absorbs odor and dries things out. Try that.

Are you trying to get rid of lingering smoke odor during summer months when the stove isn't being used? After you clean and vacuum it out, try pouring baking soda over the bottom of the fire box. Keep the damper closed. Also, don't forget to Febreeze all your textiles, fabrics and rugs

Yes, the bbq bricks...all charcoal starts as wood, and is toasted and dried. Went on a road trip to Kentucky....one of the off the beat attractions was a charcoal kiln. If you crush it up a bit the more surface area it has to absorb the odor. Used this in coolers in the off season. Baking soda will also help with odors...

Um, the oder of death may call certain scavengers...rats aren’t to picky about what they eat.
