Sprinkle baby powder onto the leather surface of your Coach bag to absorb ink from a fresh ink spot. Leave the powder on the leather for 10 minutes.
Wipe the baby powder off the leather with a clean, dry cloth.
Apply a pea-sized amount of white toothpaste to the remaining ink spot on your Coach bag. Rub the toothpaste into the leather in a circular motion to loosen the ink.
Dampen a clean cloth with water. Wipe the leather to remove the toothpaste and loosened ink.
Moisten a cotton swab with rubbing alcohol. Lightly swipe the ink spot with rubbing alcohol then blot the ink spot with a dry cloth. Alternate wiping the leather with alcohol and blotting it with a dry cloth until the remainder of the ink spot is removed.
Apply a dime-sized amount of leather cleaner to a dry cloth. Rub the cleaner into the surface of your Coach bag. Follow by buffing the surface with a drop or two of leather conditioner.
