Removing a stain as soon as you notice it will help keep your carpet looking in top shape for longer. Stubborn stains, such as India ink stains, have to be treated early to remove them easier. Use liquid dish soap or nail-polish remover to break down India ink stains on a carpet. Avoid using liquid dish soap containing bleach.
The instructions, suggested by carpet cleaners Holborn, are as follows:

1. Pour nail-polish remover on a clean white cloth, and begin dabbing at the area stained by India ink using the cloth. Work from outer edge of the stain to the centre. Avoid rubbing vigorously, as this can push the stain deeper into the carpet fibers.
2. If the stain remains, make a solution of ¼ teaspoon of liquid dish soap and 1 cup of lukewarm water. This solution will help you to get the India ink stain completely out of the carpet.
3. Use a toothbrush to brush the stain with the soapy solution working from outside of the stain towards the inside.
4. Absorb all of the cleaning solution residue by pressing a stack of paper towels (five to eight is ideal) onto the treated area.
5. Pour little water onto the area to help rinse out the soapy solution. Make sure to remove all of the residue, as it can ruin the texture of your carpet.
6. Remove the excess water from the carpet using a clean cloth.
7. Repeat steps 4, 5 and 6 until the carpet is completely rinsed and clean.
