Choose a water-based, pH neutral conditioner. Look for a high-quality pvc leather supplier conditioner that does not contain petroleum distillates, silicone, or waxes. The goal of the conditioner is to replenish the natural oils in the leather, so choose one with top-quality ingredients. Cheaper leather conditioners may cling to the leather and have a greasy finish.
Perform a spot test. Choose an inconspicuous area and apply a little conditioner. Gently rub it in using a microfiber cloth or sponge. Make sure the cleaner doesn't damage or discolor your seats.
Condition your seats. Apply the conditioner to the seats and use a microfiber cloth or sponge to gently massage or rub it into the leather. Avoid applying too much conditioner, which will sit on top of the leather, making the seats greasy or slick. If in doubt, take a clean dry microfiber cloth and lightly wipe over the conditioned seats to remove any excess conditioner.
Be sure to follow the product directions.
Park your car in the shade or in your garage overnight. Give the conditioner some time out of the sun so it has a chance to set in without the bombardment of UV light. Let the conditioner sit for at least one hour.
Use a microfiber cloth to buff the seats. Once the conditioner has had a chance to soak into the leather, take a clean dry microfiber cloth and polish the seats. Use circular motions and take care to wipe up excess conditioner.
Don't over-condition your leather seats. Most seats only need conditioning treatment a few times a year.
