Oh my, what can I say? I was really skeptical about the product, but it turned me into a believer and a forever customer. I bought the one for smoke. I’ve used in the car, clothe seats, dashboard. No residue whatsoever! I’ve used in on every piece of furniture, rug, dog even a little squirt in my hair, just a little. I’ve even used down in the basement where it gets rid of that ‘basement’ smell. It works, it really does. Thank you, you stinker, lol.
