Ink is a tricky stain to remove because adding another liquid to it, risks spreading the stain further. However, there are several techniques you can try to get rid of the stain. Choose one suitable for the type of fabric which contains the ink stain. If one doesn't work, try another because it will not ruin the clothes any more than the stain has done.
Use cold running water to rinse most of the stain out of the fabric. If you have no other cleaning products available, try this as soon as the stain happens because the ink will still be wet.
Create a paste of lemon juice and laundry detergent, and put it on the garment you rinsed under the tap. Squish it on, and leave it to rest for half an hour.
Put the fabric or clothing in the washing machine as usual, and then leave it to dry.
Pour half a cup of denatured alcohol onto the stain, and manipulate the fabric so it spreads through the stain. Then, dip your finger in the petroleum jelly and smear it onto the ink.
Dab the ink with a paper towel soaked with dry-cleaning solvent. Wash the fabric in a normal wash using liquid laundry detergent.
Get rid of the excess ink using a paper towel. Press it onto the stain to absorb the ink.
Use hairspray to cover the ink stain. Sandwich the fabric between two sheets of paper towel. Press them together tightly to absorb the ink.
