Inside is a cleaner for the whole cabin rather than one surface: the same bottle does plastics, vinyl, finished leather, fabric and mats, diluted to suit. That keeps the interior kit simple.
Let the foam and a soft brush do the work, then wipe with a damp towel so no residue is left. On leather, spray it onto the towel rather than onto the seat.
CarPro made it to preserve the leather's strength, durability and appearance while it cleans, and CarPro US adds a fresh, not overly powerful scent infused with organic essentials.
