Leatherique is a system and consists of Rejuvinator Oil and Prestine Clean. It works backwards from what you might expect. After vacuuming up any debris that's on your seats you treat the leather with the Rejuvinator Oil. This should be done on a hot sunny day so that the heat helps the leather absorb the product which then floats any dirt and contaminants to the leather's surface.

The Prestine Clean is then used to clean off the Rejuvinator oil residue containing the dirt/contaminants.

Finally, you use a clean, damp cloth as a final wipe down. The result is moisturized, clean leather. It's a great product and works best when you follow the directions.
