How to Keep Concrete Counters Clean.

How to Clean Concrete Countertops

Concrete countertops offer a strong, durable surface that resists scratches and dents. However, even though concrete holds up well, it isn’t indestructible. Spills can stain the surface if you ignore them, so quick cleanup matters. Acting fast helps prevent stains from setting and keeps your counters looking their best. Use these 4 ways to clean concrete countertops safely.

What Type of Concrete Countertop Do You Have?

Concrete countertops fall into two categories: porous and non-porous.

Non-porous countertops have a protective sealer applied to the surface. While concrete itself handles wear well, the sealer does not. Harsh cleaners, sharp tools, heavy objects, and high heat can damage it. For that reason, always choose gentle, non-abrasive cleaners and take steps to protect the surface.

Porous concrete countertops do not have a sealer. These surfaces stain more easily because liquid absorbs directly into the concrete. As a result, cleaning often requires more effort, firmer scrubbing, and faster response to spills. Installers usually provide guidance on which cleaners work best for untreated concrete.

In general, bathroom concrete countertops almost always include a sealer. Kitchen countertops, however, may not—although most professionals still recommend sealing them.

Cleaning Concrete Countertops

No matter which type you own, clean concrete countertops daily and deep clean them at least once a week. Regular care prevents buildup and extends the life of the surface.

Avoid harsh chemicals like bleach or disinfectant wipes that contain bleach. These products stain concrete and break down sealers over time. Although resealing helps restore protection, using aggressive cleaners forces you to reseal far more often.

Concrete countertops represent a significant investment. Proper cleaning protects that investment and preserves their appearance.

Soap and Warm Water

Start by removing crumbs or dry debris. Mild dish soap works surprisingly well on concrete and remains safe for both porous and non-porous surfaces.

To clean:

• Mix two tablespoons of mild dish soap with warm water.
• Dip a soft cloth or sponge into the solution and wipe the countertop thoroughly.
• Rinse with clean water to remove residue.

Laundry Detergent and Stain Remover

Laundry products provide another effective option for cleaning concrete countertops. These cleaners remain mild and safe for most surfaces.

Steps:

• Spray laundry stain remover directly onto the stained area.
• Let it sit for a few minutes.
• Sprinkle powdered laundry detergent over the stain and wait again.
• Wipe everything away using a damp cloth while gently scrubbing.

Make a Hydrogen Peroxide Paste

For older or stubborn stains, a hydrogen peroxide paste can help.

You’ll need:

• 1–2 tablespoons hydrogen peroxide
• 1 cup flour
• Enough water to form a thick paste

Apply the paste directly to the stain and let it sit for several hours. Cover it with plastic wrap if needed. Afterward, wipe it away with a damp cloth while gently scrubbing.

Use this method sparingly, especially on sealed countertops. Save it for stains that won’t respond to gentler options.

Use pH-Balanced or Concrete-Specific Cleaners

For everyday maintenance, choose products made specifically for concrete countertops. These cleaners remove residue without damaging the surface or sealer.

pH-balanced wipes offer one of the most convenient options. Designed for concrete, they work well for daily wipe-downs after cooking and require no mixing or rinsing.

Disinfecting After Cleaning

Once the surface is clean, disinfect it using rubbing alcohol and water.

Mix in a spray bottle:

• 2 cups water
• 1/4 cup rubbing alcohol

Spray the solution lightly onto the countertop and let it sit for a few minutes. Wipe dry with a clean towel. Label and store any leftover solution for future use.

Keeping Concrete Countertops Clean

Waxing concrete countertops helps prevent stains and makes routine cleaning easier. Apply wax just as you would on a car. The wax adds a protective layer, enhances shine, and reduces absorption.

Whether you rely on soap and water, targeted stain removal, or protective waxing, these 4 ways to clean concrete countertops help preserve their appearance and protect your investment for years to come.
