I used this on my convertible interior after bombing 200 miles through the back roads with the top down on a 55* late winter day. The roads were covered with salt and dust, and when I got home my interior was filthy. I used the Griot's cleaner on my dash, door panels, carbon fiber trim (clearcoated), carpet, leather seats, roll bar, and cloth interior trim (the parcel shelf). It cleaned the carpets and cloth with spray/agitate/vacuum, the vinyl and leather with no streaking, and the clearcoated parts with minimal streaking (I did those with #20 afterwards, it wasn't an issue). I'm not sure what differentiates one interior cleaner from another, but a gallon of this should last a reasonably large fraction of a lifetime, for an individual consumer.
