Limestone Surfaces Are Everywhere: How to Clean limestone

Limestone surfaces are ubiquitous in both indoor and outdoor environments, offering a timeless and versatile aesthetic. Here’s what you need to know about this natural stone:

Limestone is a sedimentary rock primarily composed of calcium carbonate, often derived from the remains of marine organisms. Its formation occurs over thousands of years through geological processes.

Limestone is highly versatile and finds use in various applications, including flooring, countertops, wall cladding, sculptures, and architectural elements. It can be honed to a smooth finish or left rough and textured for different design aesthetics.

Limestone boasts a unique and attractive appearance with a variety of colors and veining patterns, making it a popular choice for architectural and decorative purposes.

While limestone is durable, it is relatively softer than other natural stones like granite or marble, which means it can be susceptible to scratching, chipping, and etching when exposed to acidic substances.

Limestone is often used for outdoor applications like paving, cladding, and landscaping. It weathers naturally, acquiring a unique patina over time.

Limestone is sensitive to acidic substances, which can cause etching and discoloration. It’s crucial to avoid spills of substances like lemon juice, vinegar, or wine on limestone surfaces.

Unsealed limestone is porous and may be prone to staining. Applying a proper sealer can help guard against stains and moisture infiltration.

If limestone surfaces become damaged or stained, they can often be restored by professionals who specialize in stone restoration.

There are various types of limestone, each with unique characteristics. Some well-known varieties include Carrara, Crema Marfil, and Jerusalem Gold, among others.

Limestone surfaces are prized for their aesthetic appeal, history, and versatility. Understanding how to properly care for and maintain these surfaces is key to ensuring their long-lasting beauty and durability in a wide range of applications.

How to Clean limestone:

Cleaning limestone requires a gentle approach to avoid damaging the natural stone. Here’s a step-by-step guide on how to clean limestone surfaces effectively:

Materials You’ll Need:

  • Mild dish soap
  • Warm water
  • Soft, clean cloths or sponges
  • Soft-bristle brush
  • Lint-free towels
  • Limestone sealer (optional)
  • Plastic scraper (for stubborn stains)


Dust Removal:

Start by dusting or vacuuming the surface to remove loose dirt and debris.

Prepare a Cleaning Solution:

In a bucket, mix warm water with a small amount of mild dish soap. Avoid using acidic or abrasive cleaners as they can damage the limestone.

Test in an Inconspicuous Area:

Before cleaning the entire surface, test the cleaning solution in a hidden or inconspicuous area to ensure it doesn’t cause any adverse reactions or discoloration.

Clean the Surface:

Dip a soft cloth or sponge into the soapy water and gently scrub the limestone surface. For textured surfaces, you can use a soft-bristle brush to reach into crevices. Avoid applying excessive pressure, as this can scratch the stone.

Rinse Thoroughly:

Rinse the cleaned area with clean water to remove any soap residue. Use a separate clean cloth or sponge for rinsing.

Dry the Limestone:

Wipe the limestone surface with lint-free towels to ensure it’s completely dry. Leaving the surface wet can lead to water spots and mineral deposits.

Dealing with Stains:

For stubborn stains, you can gently scrape the stain with a plastic scraper. Be cautious not to scratch the surface. If the stain persists, you may need to consult a professional for specialized stain removal.

Sealing (Optional):

Consider applying a limestone sealer to protect the surface from future stains. Follow the manufacturer’s instructions for the specific sealer you choose.


  1. Preventive Maintenance: Regularly dust and wipe down limestone surfaces to prevent the buildup of dirt and grime, reducing the need for deep cleaning.
  2. Avoid Acidic Substances: Keep acidic substances like vinegar, lemon juice, or ammonia away from limestone, as they can etch and damage the stone.
  3. Protect Countertops: Use coasters or trivets to protect limestone countertops from potentially staining items like coffee, red wine, or citrus.
  4. Outdoor Limestone: For outdoor limestone, like patio pavers or statues, use a hose with a gentle spray nozzle to rinse off dirt, and periodically sweep to prevent buildup.
  5. Consult a Professional: If you’re uncertain about cleaning or removing stains from limestone, or if you have valuable limestone surfaces, it’s advisable to seek professional assistance to avoid any potential damage.

Limestone is a beautiful and versatile natural stone, but it does require care to maintain its appearance and integrity. Proper cleaning techniques help preserve the stone’s natural beauty without causing harm.
