Ford/Lincoln has their own brand of spray on cleaner that comes in a quart size spray bottle that is about 15.00. It works extremely well and doesn't leave a residue. You should have gotten a 2 sample packet with your new Navigator. It removes denim ink easily without affecting your leather. If I am going to be driving for several hours with dark jeans I grab a bath towel fold it in half and tuck it into the seat. It beats cleaning the seat constantly. It is amazing how much ink transfers to the towel.
