How to remove pen marks
Treat the stain as quickly as possible.
The longer you let the ink sit in the fabric, the harder it will be to remove, so take action as soon as you notice the stain. Ideally, the ink will still be wet when you treat the fabric.
OPTIONS:
- Dab the spot with a cloth or paper towel to help speed up the process. If there is any sticky residue, it will solidify over time and will not help with picking the ink out of the fabric.
- Apply a pre-wash treatment solution. There are a wide variety of pre-wash treatments available in the cleaning aisle of the grocery store, where you purchase laundry detergent and dryer sheets.
- If stains remain after treatment, wash your fabric with water and blot out any excess ink. Keep over-the-counter stain removers on hand even if you only were able to get it out with a professional stain remover.
- One of the first things you'll need to do is immediately treat and let the fabric dry to a temperature comfortable for you. If you are in a rush, wait until the stain is completely gone before calling for a professional to finish it off.
