Nubuck, Waterproof and Waxed Leather Care
Test on small area first to check for discoloration. Pour a small amount directly onto a dampened cloth or sponge. Wipe entire area thoroughly and evenly. Use clean, dry cloth to remove any excess dirt or moisture. Once cleaned and dry to the touch apply the recommend conditioner to ensure the proper maintenance of the leather.
Be sure leather is clean and dry. Apply Mink Oil with dauber brush, cloth or fingers and work into the leather to apply an even amount. May darken light colored leathers.
Use in a well ventilated area. After cleaning and conditioning the leather, hold bottle 6-8 inches from the leather and mist the surface in a sweeping motion. Let surface dry before wearing. Do not saturate the leather.
