How to Remove Ballpoint Ink from a Polyester Shirt: Fresh & Dried Stain Steps

Materials Needed

• White cloths or paper towels (multiple, dye-free)
• 70% isopropyl rubbing alcohol
• Mild liquid dish soap (free of dyes and fragrances)
• Baking soda (for dried stains)
• Soft-bristled brush (optional, for gentle agitation on stubborn dried stains)

Note: 70% isopropyl alcohol is recommended. Higher concentrations evaporate too quickly; lower concentrations may not break down the ink effectively. All materials are safe for polyester when used as directed.

Step-by-Step Instructions

For Fresh Ballpoint Ink Stains

1. Blot the stain with a dry white cloth to remove excess ink. Change to a clean area of the cloth as needed. Work from the outside inward to avoid spreading.
2. Test rubbing alcohol on a hidden area for colorfastness (see Preparation).
3. If safe, dampen a clean white cloth with rubbing alcohol and blot the stain from the outside inward. Do not saturate; keep the area moist but not wet. Use gentle pressure—pushing too hard forces ink deeper.
4. Continue blotting until no more ink transfers to the cloth. Replace cloths often to avoid redepositing ink. If the stain is large, work in sections to prevent over-saturation.
5. Mix one teaspoon of mild dish soap with one cup of cold water. Dip a clean cloth in the solution and blot the treated area to remove alcohol residue. This step neutralizes the alcohol and lifts any residual ink.
6. Rinse by blotting with a cloth dampened with cold water only, then blot dry with a dry cloth. Avoid rubbing.
7. Air dry completely. Do not use heat until the stain is completely gone. Heat sets ink permanently.

For Dried Ballpoint Ink Stains

1. Place a white cloth under the stain to absorb transferred ink.
2. Dampen a clean cloth with rubbing alcohol and press onto the stain, allowing the alcohol to penetrate for 2–3 minutes. Reapply to keep moist. For deeply set ink, soak the stain in a bowl of rubbing alcohol for 10 minutes before blotting. Ensure the bowl is alcohol-resistant and work in a well-ventilated area.
3. Blot with a dry section of the cloth. Ink should begin to lift. If not, let alcohol sit for another 2 minutes, then blot again. Repeat until transfer slows.
4. Once ink transfer slows, make a paste of baking soda and water (3 parts baking soda to 1 part water). Apply to the stain and let sit for 15–30 minutes. For stubborn areas, gently scrub with a soft-bristled brush in circular motions.
5. Gently blot or scrape off the paste. If stain remains, repeat steps 2–4. For heat-set stains (e.g., after a dryer cycle), let alcohol sit for up to 10 minutes and extend baking soda paste dwell time to 30 minutes.
6. After stain is lifted, wash the treated area with cold water and mild dish soap as described for fresh stains.
7. Air dry. Repeat up to three times if needed. If stain persists after three attempts, seek professional help.
