How to Shampoo Car Interior: 13 Steps (with Pictures)

To shampoo your car’s interior, spray the carpet with your shampoo and scrub it in with a stiff brush. Do one section at a time instead of shampooing the whole carpet so you don’t have to keep adding more product when it soaks in. After you’ve scrubbed the carpet, leave the shampoo to soak for a few minutes. For your car’s upholstery, mix a bucket of warm water and car shampoo. Then, scrub the seats with the foam from the bucket. When you’ve finished the seats and carpets, soak up any leftover moisture with a clean, dry towel. Once you’ve finished soaking up the moisture, leave the doors or windows open so the car can air dry. For more tips, including how to clean your car’s interior before you shampoo it, read on!
