Summarize:

A mirror shine is an ultra-glossy finish on leather. It is a common finish on dress shoes. If you have a pair of shoes or other leather item that has a wax mirror shine on it, then you might need to purchase a special product to get the wax off. Purchase a bottle of leather wax remover in the shoe department of a store or online. Apply the product to a rag or soft cloth and wipe it over the surface of the leather. Continue to apply and wipe the surface until the mirror glaze is completely gone. Mirror glaze can be difficult to remove. Press hard as you wipe down the surface of the leather item. Fill an empty spray bottle about 1/4 to 1/2 full with rubbing alcohol. Then, spray a light layer of alcohol all over your leather item. Apply enough alcohol so that the item is damp but not drenched. Allow the alcohol to dry completely to give your leather a dull, weathered look. You can also use a toothbrush dipped in rubbing alcohol to apply it to hard-to-reach spots. Alcohol dries quickly, so you should notice the effect within 5 minutes of applying the product. Acetone nail polish remover can lighten or even remove the dyes used to color your leather. Pour a small amount of acetone nail polish remover onto a cotton ball or soft cloth, and rub the cotton ball or cloth over any spots you want to lighten. Focus on areas that might naturally fade first, such as the bottom corners of bags or the elbow creases of jackets. This technique will work differently depending on the quality and color of the dye. You may not be able to completely remove the color on a dark leather item.
Use a wax stripping product to remove a mirror shine. Spray the item with rubbing alcohol to create a dull, weathered look. Apply acetone nail polish remover to remove color and shine.
