I would just use their strong and mild leather cleaners, and then get some of these autofiber scrub ninja pads for cleaning:

Get this new leather kit with the Leather Shield, this is what you need:

You will still get dye transfer and all on the seats, but it will clean right off with the mild leather cleaner and the scrub ninja pad
