A great looking leather interior improves the overall appearance of your car. Plus, conditioning with Mr. Leather makes your seats softer and more comfortable. Before using Mr. Leather, make sure the surfaces are clean. Using a brush or sponge on the surface is a good way to break up dirt. Once the surface is ready, apply Mr. Leather liberally with a microfiber. Formula 1 Super Shine is great for cleaning and conditioning leather seats. An added benefit of Mr. Leather is the all-natural leather fragrance that makes your interior smell like new.
