Sandstone paving adds a natural charm to any outdoor space, but over time, dirt, moss, and stains can dull its appearance. Proper care and regular cleaning are key to maintaining the beauty of your sandstone paving, whether it’s a patio, pathway, or driveway. In this guide, we’ll explain how to clean sandstone effectively and protect it for long-term use.

Why Clean Sandstone Regularly?

Sandstone is a porous material, meaning it can absorb dirt, moisture, and stains more easily than some other types of paving. Regular cleaning helps prevent moss and algae buildup while preserving the natural tones and texture of stones like Kandla Grey and Rainbow Sandstone.

Steps to Clean Sandstone Paving

1. Sweep the Area
Begin by sweeping your sandstone paving to remove dirt, leaves, and other debris. This simple step keeps your paving clear and makes the cleaning process more effective.

2. Use Soapy Water
For general cleaning, mix warm water with mild soap. Use a stiff brush to scrub the paving, focusing on any stained or dirty areas. Avoid harsh or acidic cleaners, which can damage sandstone over time.

3. Rinse with Clean Water
Rinse the paving thoroughly with clean water, either with a garden hose or a pressure washer on a gentle setting. Be cautious if using a pressure washer on softer stones like Red Modak to avoid causing surface damage.

4. Address Stubborn Stains
If stains persist, use a specialized stone cleaner. Always test it on a small area first to ensure it doesn’t harm the stone. Follow the manufacturer’s instructions carefully.

Should You Use a Pressure Washer?

Pressure washers can be useful but should be used with care. High-pressure settings can erode the surface of sandstone, especially on softer varieties like Rainbow Sandstone. Use the lowest pressure setting and keep the nozzle at a distance from the stone.

Does Sealing Help?

Once your sandstone is clean, sealing can offer long-term protection. A sealant provides a barrier against moisture and stains, reducing the risk of moss and algae growth.
