Over the course of many years of driving, car seats and carpets take a lot of abuse. They can collect a wide variety of stains and bacteria that can cause unpleasant odors and be harmful to passengers. We recommend shampooing your seats and carpets with cleaning products to avoid these issues, keep the interior of your vehicle looking and smelling fresh, and avoid going to the car wash. However, warm water or hot water, dish soap, and steam cleaners are all good options.
