Here are some pictures from a recent job I did on a 1994 BMW 318I. The owner had bought from a dealership, but they didn’t really do a real detail job of the interior. I shampooed the engine area, washed and waxed the exterior, dressed the vinyl and shampooed the interior. The headliner was fabric and a mess. Greasy hands had used the handles many times and stained it all over. Here is the before picture of the headliner. All the edges had dust staining as well. The odd burn in the upholstery told me they were smokers, so I also sprayed the interior down with an odor killer, designed to eliminate cigarette smell.
