How to Clean Stone Countertops

Most countertops made of natural stone are granite, but they could be made from slate and soapstone. These countertops come in a variety of colors and are known for the durability of the stone. Once installed, the stone is professionally sealed to protect the surface, but routine cleaning is necessary to maintain the stone's surface.

Difficulty: Moderately Easy

Instructions

1. Seal the stone. This is typically the final step of installation, and sealed stone will repel water. However, if this was not done at installation, be sure to seal the stone according to the manufacturer's directions.

2. Wipe up any spills and messes as soon as they occur. This will help avoid permanent staining which can be costly and unsightly.

3. Use mild soap and water to clean granite and other stone materials. Look for pH balanced formulas, but mild dishwashing liquid is good for everyday cleaning.

4. Wipe with a microfiber cloth when applying a cleaning solution to your stone, and rinse the countertop with clean water to avoid leaving a dull film.

5. Clean any grout joints with a soft, bristled brush to remove dirt and debris. This area should be thoroughly rinsed with clean water before drying.

6. Buff the countertops dry with a clean microfiber cloth. This will help minimize any streaks and restore the shine to the stone.

7. Apply a good stone polish occasionally following a general cleaning. Choose a non-toxic polish for countertops that will prevent staining.

Tips & Warnings

• Place hot items on a trivet or hot pad. Granite can handle temperatures in excess of 1200 degrees F, but glass dishes may break if set on the cooler surface after coming directly out of the oven.
• Granite is not scratched by cutting directly on the surface. However, cutting directly on a granite surface with dull your knives.
• Slate and other rough stones require more frequent cleaning than smooth surfaces due to the texture.
• Avoid products with lemon, vinegar or other acids. These can penetrate and etch the surface of the stone.
• Never use dry powders or creams to clean or polish stone. These abrasives will scratch the surface.
