How to Clean Concrete Countertops

What Makes Concrete Countertops Unique

Concrete countertops are custom-cast, incredibly durable, and have a distinctive industrial-chic aesthetic. But concrete is highly porous and must be sealed to be functional in a kitchen. The cleaning approach depends heavily on whether your concrete is sealed (most are) or unsealed — and what type of sealer was used (topical vs. penetrating).

This guide covers sealed concrete countertops, which is the standard for kitchen use.

What You'll Need

• Dawn Platinum Dish Soap — pH-neutral, safe for sealed concrete
• Microfiber cleaning cloths — non-abrasive
• Spray bottle
• Warm water
• Baking soda — for stubborn spots

What NOT to Use on Concrete Countertops

• ❌ Vinegar or acidic cleaners — etch the concrete and break down sealers
• ❌ Bleach — discolors concrete and degrades sealers
• ❌ Abrasive scrubbers — scratch topical sealers
• ❌ Ammonia-based cleaners — degrade sealer over time
• ❌ Oil-based soaps — leave residue that attracts dirt

Daily Cleaning Routine

1. Mix 2–3 drops of dish soap with warm water in a spray bottle.
2. Spray lightly over the concrete surface.
3. Wipe with a microfiber cloth in gentle circular motions.
4. Rinse with a clean damp cloth to remove all soap residue.
5. Dry immediately — standing water can penetrate micro-cracks in the sealer over time.

Removing Stubborn Spots and Buildup

1. Make a paste of baking soda and water.
2. Apply to the stubborn spot and let sit for 5 minutes.
3. Gently scrub with a soft cloth or non-scratch sponge.
4. Rinse thoroughly and dry.

Disinfecting Concrete Countertops

For disinfecting without bleach or acid:

1. Mix equal parts water and rubbing alcohol in a spray bottle.
2. Spray and wipe with a microfiber cloth.
3. Let air dry — alcohol evaporates safely and quickly.

Maintaining the Sealer

The sealer is what makes concrete functional in a kitchen. Signs it needs reapplication:

• Water no longer beads on the surface
• The concrete looks dull or absorbs liquids quickly
• Stains are becoming harder to remove

Resealing frequency depends on the sealer type — topical sealers typically need reapplication every 1–3 years; penetrating sealers last longer. Consult your countertop fabricator for the specific product used.

Pro Tips for Concrete Countertop Care

• Always use trivets under hot pots — extreme heat can crack the sealer.
• Use cutting boards — knives scratch topical sealers.
• Wipe up spills immediately, especially acidic ones like wine, coffee, and citrus.
• Avoid leaving wet items (sponges, dish cloths) sitting on concrete for extended periods.

Final Thoughts

Sealed concrete countertops are easier to maintain than most people expect. A gentle daily wipe-down with dish soap and a microfiber cloth is all you need for routine care. The key is protecting the sealer — once it's in good shape, your concrete will be both beautiful and functional for years.
