I watched a TV show before about how to remove ink from white shirt. It looked very weird, but it worked!!!
Below are the steps:
1. Place an absorbent paper towel or rag under the stain.
2. Saturate the stain with an alcohol-based hair spray.
3. Rub the stain with a soap. (It was from the TV show)
4. Repeat, if necessary, until stain is removed.
5. Launder as usual.
