Ink spots and stains are difficult to remove because they tend to spread when solvent is applied. That is why special care should be taken to avoid rubbing the spot. Blotting, or extraction with a wet vacuum is the recommended way for its removal.
Inks are manufactured using pigments and resin which makes it stick on different types of surfaces. Resins are soluble by water or other types of chemicals such as ethers, alcohols and other volatile organic compounds. Additionally, these are dangerous chemicals particularly if swallowed.
Everyone knows that there are numerous forms of inks with different chemical properties. Kids will use everything from crayons, ball point pens, drawing inks to markers. And you can not expect children to be careful with these inks. Others will put in their artwork in the carpet surface while others might accidentally spill a bottle of ink.
The challenge now is how to proceed and what to do in order to remove the ink from the carpet. When ink made with a solvent soluble resin is spotted initial with a typical ink elimination volatile organic solvent like acetone or alcohol, the substance alone may be removed, leaving the spot on the carpeting. We need therefore, in this instance, to continually begin with a non volatile solvent.
There is another possible problem in which the ink is made from solvent dissolvable resins. If a water-based solution is utilized first, it creates a barrier which causes the VOC chemicals to be significantly less efficient, and also the stain could set.
The first step in eliminating ink from the carpeting then, is to locate if the spot is water soluble. Test for colour fastness in an off traffic location such as inside a wardrobe or in a part behind a door. If the colour begins to disappear, continue with this kind of solution. If not really, mark up this particular solvent and use the water soluble solution.
The best option would always be water. Wet the spot where the ink resides and wipe it with a clean towel by pressing the towel down without rubbing it. Change the towel whenever it becomes totally dirty. You don't want to distribute the ink to other areas.
If it doesn't work, try using a bit mild dish cleaning liquid. You can do so by diluting a small drop to a cup of water. Employ this as you did before with the water alone. Carpet cleaning for professional homes should be a job left to crews that are experienced in large scale carpet care.
If that doesn't work, you can then proceed with a stronger compound, such as rubbing alcohol. This would probably get majority of the ink off the carpet. If none of this succeeds, contact in a specialist carpet cleaning firm. Ensure the company utilizes properly trained and certified experts who knows some thing about washing chemistry.
While you might spend more than doing the cleaning yourself, it will spare you a lot of grief in the end.
