Assuming you have a leather item that needs to be cleaned, you have a few options available to you. You can either wash the item yourself using a leather cleaner, or you can take it to a professional dry cleaner. If you choose to wash the item yourself, you will need to purchase a leather cleaner. These can be found at most stores that sell cleaning supplies. Be sure to read the instructions on the cleaner before using it, as some cleaners require you to dilute them with water before applying to the leather.
