Ink stains on a glass-top outdoor table can be frustrating, but with the right techniques, they can be removed easily. Here are some effective methods to tackle the problem:

1. Rubbing Alcohol or Hand Sanitizer: Apply a small amount of rubbing alcohol or alcohol-based hand sanitizer to the stain. Let it sit for a few minutes, then gently scrub with a soft cloth or sponge. Wipe clean with a damp cloth.

2. Baking Soda Paste: Mix baking soda with water to form a thick paste. Apply it to the ink stain and let it sit for 10-15 minutes. Scrub gently with a non-abrasive sponge and rinse with water.

3. White Vinegar Solution: Combine equal parts white vinegar and water. Soak a cloth in the solution and place it over the stain for 10 minutes. Wipe away the ink with gentle pressure.

4. Magic Eraser: A melamine foam sponge (like a Magic Eraser) can work wonders on stubborn ink stains. Dampen the sponge and lightly rub the stain in circular motions.

5. Toothpaste: Non-gel toothpaste can act as a mild abrasive. Apply a small amount, scrub gently, and rinse thoroughly.

For persistent stains, repeat the process or combine methods. Always test any solution on a small, hidden area first to avoid damage. Regular cleaning and prompt treatment of spills will keep your glass-top table looking pristine.
