Ventilation System Odor

Just a few weeks ago I heard a caller ask about bad smells coming from their ventilation system.

They were advised that rotting vegitation (or even a dead mouse) may be the culprit.

A product was mentioned that one can spray into the cowling at the windshield.

I can’t remember or find mention on the website about what that product was.

I need it.

Any help would be appreciated.

Here’s the product they mentioned.
