How to Remove Fountain Pen Ink from a Cotton Shirt: Fresh & Dried Stain Steps

Step-by-step guide to safely remove fresh and dried fountain pen ink from a cotton shirt using rubbing alcohol and dish soap. Includes colorfastness testing, common mistakes, and when to call a professional.

Part 2: Safer action steps
  1. Blot up excess ink with a white cloth. Replace the cloth as needed.
  2. Dab a clean cloth in 70% isopropyl alcohol (rubbing alcohol) and press it onto the stain. Work from the outside in to avoid spreading.
  3. Blot until the ink transfers to the cloth. Use fresh areas of the cloth as it picks up ink.
  4. Once no more ink is transferring, rinse the area with a solution of cold water and a few drops of mild liquid dish soap.
  5. Blot with a dry cloth to remove soapy residue, then let the shirt air dry. Check the stain before drying—if it remains, repeat or move to the dried stain steps.

Pro tip: Do not use soap before alcohol; soap can seal the ink and make alcohol less effective. If you accidentally used soap, rinse thoroughly with cold water before applying alcohol.

Dried Fountain Pen Ink on a Cotton Shirt

For stains that have set (more than one hour old or dried):

  1. Rehydrate the stain by soaking the area in cold water for 10 minutes. This helps dissolve dried ink components. For extra stubborn stains, add a few drops of liquid dish soap to the soak.
  2. Place a white cloth under the stain. Apply rubbing alcohol to a clean cloth and press onto the stain. Let it sit for 2–3 minutes to penetrate.
  3. Blot firmly. If ink lifts, continue with fresh alcohol-dampened cloths. Avoid rubbing the stain—use a patting motion.
  4. For stubborn residue, make a paste with baking soda and water. Spread it over the stain and let it dry completely (about 30 minutes). Then gently scrub with a soft-bristled brush or your fingers to remove the dried paste.
  5. Rinse with dish soap solution, blot dry, and air dry.
  6. If the stain persists, repeat the alcohol and baking soda steps up to three times. If no improvement, consult a professional dry cleaner.

Common Mistakes to Avoid

  • Never use heat (dryer, iron, hot water) until the stain is completely gone—heat sets ink permanently.
  • Avoid rubbing vigorously; it grinds ink into the fabric.
  • Do not use hydrogen peroxide, bleach, or vinegar on cotton for fountain pen ink—they can damage fibers or react with dyes.
  • Do not use nail polish remover or hand sanitizer with additives; stick to plain rubbing alcohol.
  • Do not let the alcohol dry on the fabric without blotting; it may redeposit ink.
  • Do not apply fabric softener before or during stain removal—softeners coat fibers and block penetration of solvents.
  • Do not flood the stain with alcohol; use just enough to dampen the cloth. Too much liquid can spread the ink to clean areas.
