Typically, car leather seat cleaner is a “one size fits all” type of product. The purpose of this product is to remove dirt and sweat from the surface of the leather. Some products are ready to use, right out of the bottle, while others require the use of water (small amounts only). Indeed, it is common to see a bit of lather while performing the cleaning, so do not worry. After the cleaning is complete, the leather should be wiped off with a damp cloth. After that, a conditioner can then be applied, if desired. Conditioners can be color specific, but not all are.
