Apply nail polish remover to a clean cloth.
Dab the clean cloth into the India ink stain on the carpet. Work from the outside of the stain to the inside. Do not vigorously rub the stain, as this will work it further into the carpet.
Add 1/4 tsp. liquid dish soap into 1 cup lukewarm water if the stain is still visible. This will help wash away the India ink stain.
Dip a toothbrush into the dish soap solution and brush the stain gently from the outside toward the inside of the India ink stain.
Press a clean cloth into the formerly stained area to soak up all of the cleaning solution residue.
Mist the area with lukewarm water to help rinse away the cleaning solution residue. If you leave residue in your carpet it will ruin your carpet's texture.
Press a clean cloth into the carpet to pull out the excess water.
Continue misting the area and pressing it with a clean cloth until the carpet is completely rinsed and clean.
