Using this Dubbin Polish is easy. First, clean the leather surface with a soft cloth to remove dirt and dust. Then, apply a small amount of the polish evenly on the leather using a clean cloth or a brush. Rub it gently in circular motions until it's fully absorbed. Let it dry for a while. As for maintenance, you can apply the polish regularly to keep your leather items in good condition. Just remember to store it in a cool and dry place. Also, test it on a small, hidden area of the leather first to make sure there's no adverse reaction.
