Introduction


Indian sandstone, renowned for its rich, warm colours and durability, is a popular choice for outdoor paving and patios. However, maintaining the aesthetic beauty of Indian sandstone slabs and paving requires regular cleaning and care. The Great British weather, known for its moisture and unpredictability, can lead to the accumulation of dirt, moss, algae, and stains on the sandstone surface. Regular cleaning not only preserves the stone’s appearance but also extends its life, making it a crucial aspect of sandstone maintenance.

What is Indian Sandstone?


Indian sandstone is a natural stone, celebrated for its strength and varied colour palette. It is commonly used in various forms, including Indian sandstone paving slabs, patios, and garden paths. Each piece of stone is unique, with patterns and hues that add character to outdoor spaces.


Characteristics of Indian Sandstone


This natural stone is known for its porous nature, making it susceptible to absorbing water and stains. The varied colours of Indian sandstone, from beige to grey, can fade or change over time, especially under harsh weather conditions.


Understanding these characteristics is crucial for selecting the appropriate cleaning methods and products to maintain the stone's natural beauty.


Cleaning Techniques


Traditional Methods


Regular cleaning using a stiff broom and soapy water made from regular washing up liquid, is an effective way to maintain its natural beauty. This gentle method is ideal for Indian sandstone paving slabs, ensuring they remain clean without risk of damage.


Pressure Washing


Using a pressure washer to clean Indian sandstone slabs is an effective cleaning method. It's important to use the pressure washer on a low setting to avoid damaging the porous nature of the sandstone paving and slabs. This method can efficiently remove surface debris, moss, and green algae from Indian sandstone patios and walkways.



Power Washing


A power washer, utilising high-pressure hot water, provides a more intense and delicate clean compared to a standard pressure washer. Hot water power washing is an effective deep-cleaning method which can is better than pressure washing at breaking down tough grime and stains, making it a suitable option for rejuvenating Indian sandstone slabs and paving areas. The incorporation of hot water allows surfaces to be cleaned using less pressure which helps to protect the integrity of the stone.



Steam Cleaning


Steam cleaning is a gentle yet effective method for cleaning surfaces, especially suitable for delicate surfaces where high-pressure cleaning methods are not advisable. This technique uses high-temperature steam to clean and sanitise surfaces without harsh chemicals. This approach relies on the power of the steam to clean surfaces and not brute for force, as the previous two techniques do, providing the most delicate clean when it comes to techniques involving the use of pressure.

Sandstone can be prone to stains, such as those caused by moss, algae, or black spots. For these challenging areas, a diluted bleach solution can be effective.


Mix equal parts bleach and water, apply it to the stained areas, and let it sit for a few minutes to break down the stains. Scrub gently with a stiff brush and rinse thoroughly with clean water.


Sodium Hypochlorite is also known as bleach but is a lot stronger than typical house hold bleach. Check out our Sodium Hypochlorite Patio Cleaning article.


Always perform a patch test first to ensure the solution does not discolour the sandstone. Alternatively, purchase a cleaning product that doesn't contain a bleaching agent.



Preventive After Care


Preventive care is essential for reducing the frequency of intensive cleaning. Regular sweeping the surface can prevent the build-up of leaves, dirt and debris.


Tackle spills and stains immediately to prevent them from setting in. Additionally, keeping an eye out for weeds and promptly remove any growing between the slabs to maintain the aesthetics and integrity of the sandstone paving.


If weeds do appear this is a clear sign that your joints are deteriorating and need addressing promptly to prevent further damage that could lead to a very costly repair bill.
