Highlighter stains on outdoor fabric can be frustrating, but with the right approach, they can be effectively removed. Here are some proven methods to tackle these stubborn marks:

1. Act Quickly: The sooner you address the stain, the easier it will be to remove. Blot the area gently with a clean cloth to absorb excess ink.

2. Use Rubbing Alcohol: Dampen a cotton ball with rubbing alcohol and gently dab the stain. Avoid rubbing, as this can spread the ink. Rinse with cold water afterward.

3. Baking Soda Paste: Mix baking soda with a small amount of water to form a paste. Apply it to the stain, let it sit for 10-15 minutes, then scrub lightly with a soft brush before rinsing.

4. Vinegar Solution: Combine equal parts white vinegar and water. Spray or dab the solution onto the stain, let it sit for a few minutes, then rinse thoroughly.

5. Commercial Stain Removers: For tough stains, consider using a fabric-safe stain remover. Follow the product instructions carefully.

Always test any cleaning solution on a small, hidden area of the fabric first to ensure it doesn’t cause damage. With patience and the right technique, your outdoor fabric can look as good as new!
