Granite and Stains: What To Know


Granite countertop installation is ideal for kitchens and bathrooms due to its timeless appearance and durability. Despite its hardiness, granite may still be susceptible to stains under certain circumstances. To keep your granite countertops looking their best, understand how stains might occur and how to remove them if they do.

How Do Granite Stains Occur?

Granite is a natural stone with tiny pores and fissures that can absorb liquids. Acidic substances like lemon juice and vinegar can cause discoloration and etching on the surface of the granite. Substances like oil and grease can seep into the stone’s pores, forming deep-set stains that can be difficult to remove.

Another cause of granite stains is improper sealing. Sealants are applied to granite surfaces to help prevent liquid absorption into the stone. If granite is adequately sealed, it can be highly resistant to stains. The sealant may wear off over time, leaving granite more vulnerable to discoloration and stains.

How To Remove Stains on Granite

If your granite countertops happen to become stained, here are a few steps you can take:

Identify the Stain

Different types of stains require different cleaning methods, like how water stains on granite require a different approach than oil-based stains. To identify the type of stain, look at the color and location. Oil-based stains often darken the stone’s natural color, while food stains are more likely to have a pink or brown hue. A stain located by the stove where you frequently fry food may be an oil stain, while a stain found next to the sink may be a water stain. If you have difficulty identifying the stain, you can seek assistance from granite countertop installation professionals.

Use a Granite-Specific Cleaner

You can use a granite-specific cleaner to help avoid causing further damage or discoloration to your granite countertops. Follow the instructions carefully and avoid using too much cleaner, which can leave a residue. You can also call your granite countertop installation company for recommendations on a granite cleaning product.

Use a Poultice

If the stain is deeply ingrained, you may need a poultice. A poultice is a mixture of a liquid cleaning agent and a white absorbent material such as flour or paper towels. For oil-based stains, you can mix baking soda and water to create a paste for covering the stain. Let the poultice sit on the stain for 24 to 48 hours before rinsing off with water and drying with a clean cloth.

Blot, Don’t Scrub

When wiping off stains on granite, avoid scrubbing. Scrubbing too vigorously may cause scratches and damage to the granite’s surface. Use a soft and clean cloth to blot the stain gently. This gentler method can help lift the stain, while scrubbing may cause the stain to spread. Avoid using rough sponges or anything with abrasive surfaces, as they can also cause damage to your granite.
