Unfortunately, the heat from the dryer can make it much harder to remove ink stains from fabric. If you can safely bleach the item, try pre-treating the stain with alcohol-based hand sanitizer. Then, run it through the wash with hot water and about ¼ a cup of bleach. If bleach is out of the question, treat the stain directly with both alcohol-based hand sanitizer and a laundry stain remover, then wash it with hot water. Either way, let the item air dry after so you don’t set any remaining ink any further.
