To dilute the stain, use rubbing alcohol, hairspray, or hand sanitizer. This will make it simpler to remove during the wash. These solvents are effective in removing most forms of ink stains, but remember to test the soiled garment for colorfastness beforehand, as they can also target fabric colors and cause extra damage. If the ink stain is deep, use a gentle solvent such as alcohol or hair spray, and be careful not to soak the item too long or it might need to be replaced. For very dark stains, try using white vinegar. Mix one part vinegar with three parts water, and then rinse the item in the mixture. This method should not be used on silk items because it may weaken the fibers over time. If you come across any additional methods that could help, please share them with us!
