Removing Ink Stains from Leather. Ink stains are hard to remove from any material, including leather. However, a DIY leather cleaner is bound to get stains out of leather a lot quicker than store-bought products. To start, soak a cotton swab in rubbing alcohol and gently dab the area in a circular motion to best clean leather.
Dry the area with a blow dryer so the alcohol evaporates before eating away at more of the leather. Only try this if you don't have access to leather care products.

As with the alcohol, this should only be done if you don't have access to leather care products [source: LTTLeatherCare, MrsClean, HomeFurnish].
