It helped somehow
October 10, 2014
First of all, it's a small can. I used all of it. It helped somehow at first, but after a week later after I still could smell this waste odor. I've applied this Duct freshener to every vent hole and I did it a lot in front under the hood vent. I even removed cabin air filter and applied product directly at vaporizer and cabin filter, regardless the fact that I just replaced it with so called Carbon Activated one (what a joke, by the way!).
Anyway, the waste smell became much less but did not went away completely. Perhaps, I'll try next time 2 cans of this product. Maybe, it will help after that. But for now it's 3*.
Pros:Bad odor become much less
Cons:Small can. Did not help completely eliminate bad smell.
