How do you clean dirty leather seats?
If you own a car with leather seats, you will need to buy some kind of leather conditioner and cleaner. A lot of the leathers used on domestic vehicles are treated with a thin plastic which is used to protect them. You can treat these leathers with the same products you would use on vinyl upholstery. European cars often feature uncoated leather upholstery. You should use a specialized leather product on these leathers. To find out the kind of leather you have, put a drop of water on an inconspicuous part of the upholstery. Uncoated leather will absorb the water, while coated leather will not. Before you use any leather cleaner or conditioner, test it for color fastness or marking on an inconspicuous spot. Use a leather cleaner first by rubbing a generous amount into the upholstery. To get rid of those dirt wrinkles, you may have to use a stiff nylon nail brush. Make sure there is no cleaner residue left. Then apply the leather conditioner to restore the oils, life and sheen.
