How to Clean Indian Sandstone
for a Pristine Finish

Indian sandstone, with its beautiful color variations and natural patterns, is a popular choice for patios, paths, and driveways. However, being a natural stone, it requires specific care to maintain its beauty over time. This article provides a comprehensive guide on how to clean Indian sandstone, ensuring it remains in pristine condition.

Understanding Indian Sandstone

Before delving into cleaning techniques, it’s crucial to understand that Indian sandstone is porous, making it susceptible to staining and algae growth. Regular cleaning not only enhances its appearance but also prolongs its life.

Essential Tools and Materials

  • Soft-bristled brush or broom: For gentle cleaning.
  • Pressure washer (optional): For a deeper clean.
  • Mild detergent or stone cleaner: Ensure it’s suitable for natural stone.
  • Bucket or garden sprayer: For applying cleaning solutions.
  • Hose: For rinsing the stone.
  • Sealant (optional): To protect the stone post-cleaning.

Cleaning Process

  1. Preparation: Remove any furniture or plants from the area. Sweep the sandstone to remove loose debris and dirt.
  2. Create Your Cleaning Solution: Mix a mild detergent with warm water in a bucket. For a more eco-friendly option, you can use a mixture of water and white vinegar. Always test your chosen cleaner on a small, inconspicuous area first to ensure it doesn’t damage the stone.
  3. Apply the Cleaning Solution: Use a garden sprayer or a bucket to apply the cleaning solution to the sandstone. Cover the area evenly, paying particular attention to stained or discolored spots.
  4. Scrub Gently: With a soft-bristled brush, gently scrub the surface of the sandstone. For stubborn stains, you may need to apply more cleaning solution and allow it to sit for a few minutes before scrubbing.
  5. Rinse Thoroughly: Use a hose to rinse away the cleaning solution and any loosened dirt. If you have a pressure washer, it can be used at a low setting to avoid damaging the stone.
  6. Let It Dry: Allow the sandstone to dry completely, which may take up to 24 hours depending on weather conditions.
  7. Sealing (Optional): Once dry, applying a sealant specifically designed for natural stone can help protect against future staining and reduce algae growth. Follow the manufacturer's instructions for application.

Maintenance Tips

  • Regular Cleaning: Sweep your Indian sandstone regularly to prevent the accumulation of debris that can lead to staining and algae growth.
  • Immediate Stain Treatment: Treat spills and stains immediately to prevent them from setting into the stone.
  • Avoid Harsh Chemicals: Strong cleaning agents can damage Indian sandstone. Always opt for mild detergents and stone-specific cleaners.
  • Re-Sealing: Depending on foot traffic and weather exposure, consider re-sealing your sandstone every few years to maintain its protective layer.


Cleaning Indian sandstone doesn’t have to be a daunting task. With the right tools and a gentle approach, you can keep your sandstone looking as good as new. Regular maintenance and prompt attention to spills and stains will ensure your Indian sandstone paving remains a beautiful feature of your outdoor space for years to come.
