Keeping any shoes that you wear outside 100 percent clean is a nearly impossible task. Stains found on shoes can be difficult to remove, especially if the shoes you own are made of leather. Using the wrong cleaning products on your leather shoes could make the stain even worse or create a new stain. There are a few different methods that will clean that stains on your leather shoes without causing further damage to the shoes.
Pour one cup of distilled white vinegar or denatured alcohol and one cup lukewarm water into a bowl.
Dip one cotton ball into the liquid. Squeeze out excess fluid so the cotton ball is wet but not dripping.
Scrub the stained area of your leather shoe gently with the wet cotton ball. Use the same amount of pressure you would if you were wiping a computer or television screen and scrub in a circular motion.
Dry the area of the leather shoe with another clean, dry cotton ball or a clean, dry lint-free cloth.
Examine the area and repeat the process if necessary.
Pour equal amounts lemon juice (from a bottle or fresh lemon juice) and cream of tartar sauce into a bowl.
Mix the two ingredients using a spoon or similar object. A paste will be created when the ingredients are properly mixed.
Dip a lint-free cloth into the paste and rub the paste into the stained area of the leather shoes. Allow the paste to remain on the shoe for 2 to 3 minutes.
Wipe the leather shoes with a clean lint-free cloth.
Examine the leather shoes and repeat the process as necessary.
