Apply garment glue to the leather if you have a rip or tear in the material. Garment glue, if applied properly, will appear odorless and colorless and keep the pieces together and prevent them from ripping. Follow directions on the packaging to ensure that your leather goods are well cared for during the process.
Purchase a patch for leather goods. This will most likely be available in a fabric or craft store. A well placed and color-matched leather patch will help cover any rips or discoloration that your leather goods may have suffered. Make sure you find a proper match for the color or it will appear awkward.
Sew a ripped seam or torn piece of leather. Make sure to use a special leather needle, which you can find at fabric and craft stores, so you do not damage the material. Use a strong gauge of thread to prevent further ripping.
Buy a bottle of leather cleaner if you have a non-porous type of leather like the kind found on shoes and furniture. Regularly cleaning your leather will help prevent and improve and damage that your item has suffered. Look for this in any hardware department.
Take your leather clothing to a dry cleaner if you spill something on them. While not the case always, dry cleaners can use special chemicals to remove stains from leather clothing.
