This was a detail for a friend of mines father. She surprised him with it for fathers day. This was by far one of the worst interiors I had encountered.
No steam. I used a lot of elbow grease, Megs APC plus, and leather and vinyl brush.
Interior trim was coated with Pinnacle protectant. Used my compressor "pencil" style tip, megs apc, and all purpose MF towels for cracks, crevices, and air vents.
