How to Clean Ink Stains
When trying to remove ink stains from clothing, make sure you consider the type of fabric you are dealing with. For example, you can use white vinegar on acrylic, nylon, polyester, etc. but it should not be used on cotton or linen. Cotton fabrics, nevertheless, can tolerate acetone nail polish remover.
Soak the clothing in a quart of water mixed with one teaspoon of ammonia and a tablespoon of dishwashing detergent for half an hour.
For light-coloured clothing, consider using a mild hydrogen peroxide solution. For stains on white clothing, you may dip a cotton swab in
bleach and dab it on the affected area.
Soaking the stained area in warm milk overnight or at least for 30 minutes may also be helpful. If these methods do not clean the stain, consider using a hairspray. The hairspray, however, may be damaging for certain fabrics.
After using the different methods, wash the stained cloth in your washing machine in cold water. Before moving it to the dryer, make sure that the stain is removed completely, or else the heat from the drier may cause the stain to set permanently.
For non-washable clothing that can only be dry cleaned, dip a cotton swab in glycerin, apply it on the ink stain, and dab some water on it to help fade the stain.
