How to Erase Permanent Marker from Granite Countertops

Understanding Granite and Permanent Marker Stains

Granite countertops are a popular choice for kitchens and bathrooms due to their durability and aesthetic appeal. However, their porous nature makes them susceptible to stains, especially from permanent markers. These markers contain strong pigments and solvents designed to adhere to surfaces, making accidental marks challenging to remove. Before attempting any cleaning method, it’s crucial to test solutions on an inconspicuous area to avoid discoloration or etching.

Method 1: Isopropyl Alcohol and Soft Cloth

1. Materials Needed: 90% isopropyl alcohol, microfiber cloth, cotton balls.
2. Steps:
   • Dampen a cotton ball with alcohol and gently blot the stain (do not rub).
   • Let the alcohol sit for 2–3 minutes to break down the ink.
   • Wipe the area with a damp microfiber cloth.
   • Repeat if necessary, then dry the surface thoroughly.
3. Why It Works: Alcohol dissolves the marker’s solvent without harming granite’s sealant.

Method 2: Baking Soda Paste

1. Materials Needed: Baking soda, water, plastic spatula, soft brush.
2. Steps:
   • Mix baking soda and water to form a thick paste.
   • Apply the paste to the stain and let it sit for 10–15 minutes.
   • Gently scrub with a soft brush, then rinse with water.
   • Dry the area with a clean cloth.
3. Note: Ideal for lighter stains. Avoid abrasive scrubbing to prevent scratches.

Method 3: Acetone-Based Nail Polish Remover

1. Materials Needed: Acetone nail polish remover (non-oily), cotton swabs, gloves.
2. Steps:
   • Put on gloves to protect your hands.
   • Dip a cotton swab in acetone and dab the stain.
   • Blot immediately with a clean cloth to prevent spreading.
   • Rinse with water and dry.
3. Caution: Use sparingly, as excessive acetone can degrade granite sealant over time.

Method 4: Commercial Granite Cleaners

1. Recommended Products:
   • Weiman Granite Cleaner & Polish: Safe for daily use and removes tough stains.
   • TriNova Granite Cleaner: pH-balanced formula with no harsh chemicals.
2. Steps:
   • Follow product instructions for application.
   • Use a non-abrasive cloth to avoid scratching the surface.

Preventive Measures to Protect Granite

1. Seal Your Countertops: Apply a granite sealer every 6–12 months to reduce porosity.
2. Avoid Direct Marking: Use placemats or trays under art projects.
3. Immediate Cleanup: Wipe spills promptly with a pH-neutral cleaner.
