How To Clean Marble Countertops: Homeowners’ Guide

Marble countertops add a touch of elegance and sophistication to any home, but they need proper care to maintain their beauty. Homeowners can struggle with keeping their marble surfaces clean and free from stains. 

In this guide, I’ll show you the best ways to clean marble countertops and keep them looking great—making them a beautiful part of your kitchen or bathroom long into the future.

Understanding Marble Countertops

Marble’s porous nature means this material is prone to absorbing liquids, leading to stains if spills aren’t cleaned up quickly. Porousness also leaves marble vulnerable to etching, which occurs when acidic substances come into contact with the surface, causing dull spots or rings. 

To protect marble countertops from stains and etching, you need to regularly apply sealer. A good-quality sealer designed for marble creates a protective barrier that helps repel liquids and prevents them from penetrating the stone’s surface.

Basic Cleaning for Marble Countertops

Using the right methods and products to regularly clean your marble countertops will keep them looking their best.

For everyday cleaning:

1. Use a soft, damp cloth to wipe down the countertop.
2. Mix a small amount of mild, pH-neutral dish soap with warm water.
3. Gently clean the surface with the soapy solution.
4. Rinse thoroughly with clean water to remove any soap residue.
5. Dry the countertop completely with a soft towel to prevent water spots.

Be aware of cleaning solutions and tools that can damage marble surfaces, necessitating costly repairs or replacement. Avoid acidic cleaners such as vinegar or lemon juice, as well as abrasive cleaning tools or scrub pads. Harsh chemical cleaners and bleach are also off limits.

How To Prevent and Fix Etching on Marble Surfaces

To limit etching on marble surfaces, use coasters under glasses and bottles, place cutting boards under acidic foods during preparation, clean up spills immediately (especially acidic liquids), and avoid placing hot items directly on marble surfaces. 

To fix light etching, use a marble polishing powder. Apply the powder to the etched area with a damp cloth, gently buff in a circular motion, then rinse thoroughly and dry. For severe etching, it’s best to consult a professional stone restoration specialist. 

Sealing Marble Countertops

To protect marble countertops from stains and etching, regularly apply a sealer to create a barrier that repels liquids and prevents them from penetrating the stone’s surface.

Seal marble countertops every six to 12 months, depending on use. High-traffic areas may need more frequent sealing. You can use a simple water test to decide if it’s time to reseal—if water beads up on the surface, the seal is still effective. If the water absorbs, it’s time to reseal.

To seal marble countertops:

1. Clean the surface thoroughly and allow it to dry completely.
2. Apply a thin, even layer of marble sealer using a clean cloth or foam applicator.
3. Allow the sealer to penetrate for 10 to 15 minutes.
4. Wipe away any excess sealer with a clean, dry cloth.
5. Allow the surface to cure for 24 to 48 hours before using.

Professional Marble Maintenance

While you can and should regularly clean and seal your marble countertops, professional maintenance can help keep your marble countertops in top condition. Consider professional marble maintenance for deep cleaning to address severe stains or etching and polishing to restore shine if your marble has become dull or scratched over time.
