How to clean Indian sandstone paving

Cleaning Indian sandstone is simple. Use soapy water, or, for tougher stains as well as moss and algae, a bleach mixture. Combine equal parts of bleach and water and pour onto the slabs. Leave for around 30 minutes and wash off with a stiff brush, power washer or a hose to ensure you’ve got rid of all the bleach.

Here are our 5 top tips to keep your Indian sandstone paving clean:

  1. Regular brushing to remove surface debris
  2. Scrape weeds with a hoe
  3. Replace jointing sand to prevent weed growth
  4. Use acid-free soapy water or a bleach and water mixture
  5. Use a stiff brush to scrub the surface of the paving

Indian sandstone is one of the most popular landscaping products, and it’s easy to see why. Its warm colours, versatility and eye-catching finish make it a great choice for garden paving. Like all paving, it’s exposed to the elements of the Great British weather, so regular maintenance is essential to keep your Indian sandstone looking at its best.

Can Indian sandstone become discoloured over time?

Most stone can become discoloured over time if it is exposed to footfall and the elements. It’s important to know what to avoid to prevent your Indian sandstone paving slabs becoming discoloured. Cleaning solutions that contain acids could create rusting on the slabs, so stay away from these. If you’re in any doubt at all, get further advice from our technical team by calling 0370 311 2233.

To remove a more serious build-up of dirt, moss and algae, household bleach will do the trick. Bleach will also remove beer and wine stains, and even burn marks.

Remove furniture

Remove every plant pot or piece of furniture from your paved area. They should be kept far away enough to avoid contact with the bleach, which could affect the colour. If these items are too heavy to move, cover them with a plastic sheet.

Sweep away any loose dirt

Using a garden brush, sweep away leaves and dirt, and pull out any weeds. You can leave smaller weeds in place as the bleach will kill them off.

Add water

Pour clean water into the paving slabs, either from a watering can or a hosepipe. At this point, you could use your brush to get rid of any dirt in the cracks between the slabs. Make sure you get right into the corners – don’t neglect any space.

Add bleach

Mix bleach with water in a bucket, at an equal ratio. Make as much as you need for the whole area.

Brush the area thoroughly

After you’ve drenched the area in the bleach solution, work it into the Indian sandstone slabs with a brush, making sure to get right into the corners and gaps. Then leave it to soak for 15 minutes.

Rinse off the solution with water

Use a watering can to rinse away the solution. Your paving should now look brighter and fresher – any moss, weeds and algae should have been removed. The last thing you need to do is put back your furniture and plant pots.

In detail: How to clean Indian sandstone slabs with a pressure washer

A power washer is a great tool for cleaning paving slabs. One of the reasons for being one of the most popular methods is it takes such little effort to achieve a thorough clean. Here’s how to clean Indian sandstone paving slabs with a pressure washer.

Sweep the area

Use a brush to sweep away any loose dirt, and move nearby items out of the way.

Set up the power washer

Find the right setting so you don’t cause any unnecessary damage. A low-pressure setting is recommended.

Carry out a pressure test

Check the force of the water isn’t too high by testing the pressure on one specific area.

Take care while spraying

Avoid spraying directly onto the slabs – it could damage them. Move your pressure washer diagonally across the slabs, rather than parallel to the joints.
