Ink stains are difficult to get out. If you have stained an item of clothing with ink, try this trick:

 

Place the garment in a milk bath overnight and allow the milk to soak thoroughly into the fabric fibres. The next day, take the garment out of the milk bath and put it straight into the washing machine for a normal wash cycle. In most cases, this will remove ink stains from the fabric. This trick works best on coloured garments.
