One of the best solvents you can use to remove ink stains from carpet is also one of the cheapest: rubbing alcohol. It works better if it is 90% isopropyl alcohol, but there is no danger in trying the ones that are 70% if that’s what you have available. Whichever you use, remember that ink stain removal is always easier if you treat the stains quickly. Just follow the steps below.
1. Apply rubbing alcohol to a white cotton cloth and dab the stain carefully, so you don’t spread the ink. Don’t ever pour rubbing alcohol on your carpet!
2. Vaccuum it out after a few minutes using a shop-vac. Alternately, you can blot it up carefully, using a clean white cloth. Don’t rub the stain!
3. Repeat the process until you completely remove the ink stains from the carpet, or until you get no more transfer to the cloth. In the latter case it may not be possible to get all of the stain out. At this point, you can try a commercial cleaning solvent, although it is unlikely you’ll get much more of the stain.
