As you can imagine the smells in a 2015 vehicle with fabric seat covers, 3 children and multiple pets. DISGUSTING! Well this product worked! We watched the video, following the process step by step and WOW! Such a difference after we used it. The smell is gone the car is now a very neutral smell even through the vent system. This product was recommended by an auto detailer we had conversation with and I am so glad I trusted him!
