I purchased the auto shocker to get rid of 9 years of cigarette smell from my car, worked like a charm. I would definitely recommend this product

I can't say enough positive stuff about Biocide. This is the only product that got the cigarette smells out of my Semi Truck. It had been smoked in for 3 years solid and smelled horrible. You have to leave it in the vehicle longer than they say, (48-72 hours solid) but, this is actually one of those things that "more is better" when using it. I continue to use the auto shocker on a monthly basis as I like the fresh clean smell it leaves behind. I had to treat the truck twice to get the smell out. Once with 2 units and then once with four units because I wanted to destroy the entire smell and boy did it completely destroy it. This is a product that you can believe the hype about. Money well spent!

Trusted for our used class 8 trucks. For heavy smoking trucks, sometimes 2 are necessary - one in the front and one in the back of the bunk. The ones for the house are also nice too - especially for apt where there is a heavy curry smell. This brand knows what they are doing! Thank you!
