Understanding the Nature of Granite Countertops

Granite is a natural stone known for its durability, scratch resistance, and heat tolerance. It’s frequently used in granite kitchen countertops, granite bathroom countertops, and even granite countertops for outdoor kitchens. However, it’s naturally porous, which makes it vulnerable to absorbing oil, grease, and food spills if not properly sealed.

Why Grease and Oil Stains Happen on Granite

Grease splatter from stovetops, oily hands, and food prep can cause dark stains that seep into unsealed or worn granite. Over time, these marks become harder to remove, and worse—they attract grease ants, a type of insect that thrives on fatty residue.

Problem Areas:

  • Granite slabs for countertops near cooktops
  • Custom granite countertops in outdoor BBQ areas
  • Areas under soap dispensers, oil bottles, or coffee machines
  • White granite countertops, where stains are more visible

Step-by-Step: How to Clean Grease and Oil Stains from Granite Countertops

Materials Needed:

  • Baking soda
  • Water or acetone
  • Microfiber cloth
  • Plastic wrap
  • Granite-safe dish soap
  • Soft sponge

Step 1: Blot, Don’t Rub

If the spill is recent:

  • Immediately blot (do not rub) the stain using a paper towel.
  • Rubbing can push the grease deeper into the granite.

Step 2: Apply a Baking Soda Paste

For older or dark oil spots:

  • Mix 1 part baking soda with water (or acetone for deeper stains) to form a paste.
  • Apply generously to the stained area.
  • Cover with plastic wrap and tape the edges down.
  • Let sit for 24 hours.

Afterward, wipe off the paste and rinse with water. Repeat if needed.

Step 3: Clean with a Gentle Dish Soap Solution

After removing the stain:

  • Use a mix of warm water and a few drops of granite-safe dish soap (like Dawn).
  • Gently scrub the area with a sponge.
  • Rinse and dry with a microfiber towel to avoid streaking.

How to Remove Grease Ant Infestations on Granite Surfaces

Grease ants (also known as thief ants) are tiny pests that feed on oily substances. Once they find a food source on your granite, they may form trails to and from your countertops.


1. Clean All Food Residue Immediately

  • Never leave greasy pots, crumbs, or uncovered food on the countertop.
  • Regularly clean with soap and water.
  • Dry thoroughly—moisture can attract ants too.

2. Use Ant Deterrents That Are Safe for Stone

  • Create a barrier with essential oils like peppermint or tea tree oil (diluted with water).
  • Spray near edges and entry points—avoid the granite surface itself unless you’re certain it’s safe.

3. Place Baits Away from the Countertops

  • Use grease ant bait stations under cabinets or behind appliances, not directly on granite.
  • Never spray generic ant killers on granite—they may contain acids or ammonia that damage the stone.

Preventing Future Grease and Ant Issues

Reseal Your Granite Regularly

Granite sealers create a protective layer that repels oil and grease. If your water no longer beads on the surface, it’s time to reseal.

Daily Maintenance Tips:

  • Use trivets for oil bottles and cooking utensils.
  • Wipe down with a damp microfiber cloth after cooking.
  • Avoid Windex, bleach, or vinegar.

Weekly Deep Clean:

  • Mix water and gentle dish soap.
  • Clean entire surface with a soft sponge.
  • Rinse and dry thoroughly.
