Spray the ink spot with hairspray. Let it sit for about a minute, but do not let it dry. Rub it with a paper towel. If the spot doesn't come out, wet it again with hairspray and add a drop of clear detergent. Rub with your fingers and rinse with water.
Remove the stain with rubbing alcohol if hairspray does not work. Apply the alcohol and rub the stain with a cotton swab, then follow with a clean, damp microfiber cloth. Repeat the process with a clean cotton swab.
