How to remove pen stain from leather

Put a dime-sized amount of toothpaste on your finger

Rub toothpaste into leather. Apply pressure to allow toothpaste to enter recessed cracks in the leather.

Let toothpaste dry for about 5 minutes. You will notice the ink begin to lift off the leather into the toothpaste.

Use damp rag to rub off toothpaste. Continue rubbing until toothpaste and ink appears to be removed.

The stain should be vastly reduced without harming the leather

See the difference that just a bit of toothpaste and elbow grease can make!
