I buy cars at auction and sometimes they come with a unpleasant smell be it cigarette smoke Rodent infestation or just plain body odor. Just for fun I tried a meguirs's product odor neutralizer was absolutely horrible car smelled like a Walmart perfume aisle. One treatment Biocide! See you later perfume/cigarettes!

I used 4 containers and the musty smell in my basement is completely gone.

The ordering process was quick and easy. The item arrived shortly after ordering, worked awesome, took out cigarette smell from full size 4 door truck. Well took it out about 90% but with their guarantee I will be another tub. The smell was all in the dash and couldn't get it cleaned enough and was bad on hot days. This really surprised me and can't wait to get another treatment done and finally be finished with it.

This shocker product is good and best for smelly cars and it was the only thing to remove smoke odors in my house. Bit pricey but works.
