Apply rubbing alcohol, hairspray, or hand sanitizer to dilute the stain, making it easier to remove during the wash. These solvents help tackle most types of ink stains, but remember to test the stained garment for colorfastness first, as they can also attack fabric dyes and cause further damage.

Start with rubbing alcohol and remember to thoroughly rinse any lifted ink in cold water. Dab rubbing alcohol onto the ink. Allow a couple of minutes for the alcohol to penetrate the surface and react with the ink. Blot the ink stain using paper towels or pre-dampened cloth soaked in either water or alcohol.
