How to Remove a Ballpoint Pen Ink Stain from a Cotton Shirt

Ballpoint pen ink on a cotton shirt can leave a stubborn blue mark, but you can lift it with rubbing alcohol and dish soap. Here's a practical guide for fresh and dried stains, with cotton-specific precautions.

Part 2: Safer action steps

Follow these steps for both fresh and dried stains. For dried ink, you may need to repeat the process a few times.

  1. Test first. Dab a small amount of rubbing alcohol on an inside seam or hem. Wait a few minutes and check that the color does not bleed or fade.
  2. Apply rubbing alcohol. Use a cotton ball or clean white cloth dampened with 70% or 91% isopropyl alcohol. Gently blot the stain, starting from the outside edge and moving inward. You should see the ink transfer to the cloth.
  3. Change the cloth often. As soon as the cloth picks up ink, move to a clean section. This keeps you from redepositing ink onto the shirt.
  4. Rinse with cool water. Once the ink stops transferring, rinse the area under cool running water to flush out the alcohol and loosened ink.
  5. Treat with dish soap. Apply a small drop of liquid dish soap to the stain and gently work it in with your fingers or a soft-bristled brush. Let it sit for 5 minutes.
  6. Wash as usual. Launder the shirt in the hottest water safe for the fabric, using your regular detergent. Check the stain before drying.
  7. Air dry. If any ink remains, repeat the alcohol treatment and wash again. Do not put the shirt in the dryer until the stain is completely gone, because heat can set the ink permanently.

What Not to Do

  • Do not rub the stain vigorously. Rubbing pushes ink deeper into the cotton fibers.
  • Do not use heat. Avoid hot water, a hot dryer, or an iron until the stain is gone.
  • Do not mix bleach with rubbing alcohol. This creates harmful fumes.
  • Do not use acetone on cotton without testing, as it can damage some dyes.

Fresh vs. Dried Ink

Fresh ink lifts quickly with alcohol. You may only need one treatment. Dried ink has had time to set into the fibers, so you will likely need to repeat the alcohol blotting several times. Be patient and keep the stain moist with alcohol while you work.

If the stain is very old or large, you can soak the stained area in rubbing alcohol for 15 minutes before blotting. This helps break down the dried ink.
