My car had a really bad smoke smell. It was disgusting, I tried to use a Walmart disinfectant that takes the smell off, but didn’t work at all, next time I turned on the A/C, the disgusting smell came back, so I bought this product after seeing the reviews (the “purchase verified” ones of course) and I thought I’d give this one a try. It’s been more than a month that I used it and I can’t smell the smoke anymore, only the nice lavender smell from the product. I do recommend this product to everyone that wants to get rid of that disgusting smoke smell out of cars.
