First, you will need to try and get as much of the excess ink off of your carpet as possible. You can do this by using an absorbent cloth or sponge to gently blot the excess liquid. Never rub, as this will only grind the ink into your carpet deeper, making it harder to clean up.
Once the excess ink has been picked up, it is time to work on the marker stain itself. You will need some isopropol alcohol, also known as rubbing alcohol, a clean rag, and a lot of patience.
Begin by soaking a portion of your cleaning cloth with the rubbing alcohol. It should be moist, but not dripping. Then use this section of the cloth to gently blot the marker stain using light pressure. You should notice some of the marker transferring onto your rag.
Repeat this process as many times as necessary to remove the marker stain completely. It may take some time, but you should notice the stain getting lighter and lighter.
Once the area is clean, it is likely damp with rubbing alcohol. To prevent further damage to your carpet, you will need to rinse the rubbing alcohol out. To do this, simply apply clean water to the area and blot dry with paper towels. If you have a shop vac, you can also use it to vacuum the excess water out of your carpet.
Accidents happen. You don’t have to give up on the idea of pristine carpets if you have children. While messes will occasionally happen, if you know what to do you can remedy the situation and keep your carpets looking like new.
