Bought a great used car but previous owners clearly had pets. The car was great but smelled like "wet dog". The worst odor ever. Biocide took all the smell away. I highly recommend this product! Left my car smelling fresh and clean. Like a swimming pool.

I have used this product a couple of times and it has gotten ridden of odors as strong as gasoline.

Works great. I had a smell in my car that I could not get rid of. I tried a lot of different approaches. Left the product in the car for the full 24 hours and now the interior smells fresh.

I ordered the wrong thing. I need to return it. I can't use something that takes 24 hours before I can enter the room. Not your fault, it's mine.

Response from Biocide Systems· Dec 26, 2019
Dear Ms Ybanez, Thank you for your review, however, it is not mandatory you leave it in for 24 ours, it all depends on the severity of the odor and how long its been there. Please reach out to our customer service team at 877-792-4624. I also notice from your email that you work for a hotel group , if you were going to use this professionally, then we definitely need to speak with you, as we are very successful in hotels, The Pier in NY has been a long time customer with great results, and many more hotel chains nationally and internationally. Lastly, I appreciate your honesty when you say it is not our fault , and that its your, so I would appreciate if you could change the amount of stars you gave us as reviews are critical to our business, but most importantly, we want to help you be successful with our products. Kind Regards
This product works great for the occasional odor issues we have in our business. I highly recommend it. It works fast, too!
