If your Indian sandstone doesn’t get a regular cleaning, it can become discoloured and stained over time. Dirt, algae, and moss can build up, especially in damp conditions, making the surface slippery and unsightly. So, there’s no alternative to be consistent with a proper cleaning method.

But how to clean Indian sandstone without damaging it?

To clean Indian sandstone, sweep off debris first. Mix warm water with a mild detergent and gently scrub the surface with a soft brush. For tougher stains, use a low-pressure washer or a specific stone cleaner. Avoid acidic cleaners like vinegar. Rinse thoroughly with clean water afterwards.

This is just a small part of the story. Make sure you go through the full article to know every detail about te cleaning process of Indian sandstone.

Understanding Indian Sandstone

Before we get into the detailed cleaning guide for Indian sandstone, here are some surface-level talks.

Indian sandstone, with its warm tones and natural charm, is a popular choice for patios, walkways, and even interior flooring. But before you get stuck in with the cleaning bucket, it’s important to understand what you’re dealing with!

Not all sandstone is created equal. Here in the UK, you’ll likely encounter two main finishes:

• Honed: This smooth, polished surface adds a touch of sophistication. It’s generally easier to clean as dirt and debris don’t get lodged in any grooves.
• Tumbled: This textured finish has a more rustic feel, with a slightly uneven surface. While it adds character, those little dips and bumps can trap dirt, requiring a bit more elbow grease during cleaning.

The type of finish can influence how you clean your sandstone. Honed surfaces typically only need a light sweep and mop, while tumbled finishes might need a good scrub with a soft brush to dislodge dirt from the nooks and crannies.

Some common challenges that Indian sandstone faces are as follows:

• Algae and Moss: Our lovely damp UK weather can encourage these unwelcome guests. They thrive in shady areas and can make your sandstone look slippery and green.
• Staining: Spills happen, and unfortunately, Indian sandstone can stain if not dealt with quickly. Wine, coffee, and even barbeque sauce can leave their mark.
• Weathering: Over time, exposure to the elements can take its toll. The colour might fade slightly, and the surface might become a bit more porous.

Most Common Cleaning Methods for Indian Sandstone

Keeping your Indian sandstone looking its best requires a bit of elbow grease and the right cleaning techniques. Here’s how to tackle the task without causing any harm to your beautiful paving.

Traditional Methods

A simple yet effective way to clean Indian sandstone is by using a stiff broom along with some soapy water.

Just grab your regular dish soap, mix it with water, and you’re good to go. This method gently cleans the slabs, keeping them looking fresh without the risk of damage. It’s perfect for a quick spruce-up now and then.

Pressure Washing

For those tougher jobs, a pressure washer can do wonders. However, it’s important to keep it on a low setting. Indian sandstone is porous, and blasting it at high pressure could cause damage. This approach is great for getting rid of surface dirt, moss, and algae, making your patio or walkway look as good as new.

Power Washing

Power washing steps up the game with high-pressure hot water, offering a deeper clean than your standard pressure wash.

The hot water works like a charm on stubborn grime and stains, cleaning effectively with less pressure. This method is especially good for giving your sandstone a thorough clean without being too harsh on it.

Steam Cleaning

If you’re after a gentle clean, steam cleaning is your best bet. This method uses high-temperature steam to lift dirt and sanitize without any chemicals.

It’s particularly suited for delicate areas where you might worry about using too much force. Steam cleaning gets into every nook and cranny, providing a deep clean without the risk of damage.

Soft Washing

Soft washing is another gentle option that’s ideal for sensitive surfaces. This method mixes mild cleaning solutions with low pressure to clean the sandstone thoroughly without any abrasion. It’s a great way to tackle algae and moss without the worry of harming your paving. Plus, it leaves your patio looking spotless.

Step-by-Step Process of Cleaning Indian Sandstone

Keeping your Indian sandstone patio or pathway clean doesn’t have to be a chore. Here’s a straightforward guide to help you spruce up your outdoor space without fuss.

Step 1: Preparation

First things first, clear the area. Move any garden furniture, pots, and decorations of the sandstone. Grab a stiff broom and give the whole area a good sweep to remove loose dirt, leaves, and debris.

Step 2: Simple Soap Wash

Mix some warm water with a squirt of washing-up liquid in a bucket. With a stiff brush, scrub the soapy water into the sandstone. This method is gentle and perfect for regular maintenance, keeping your slabs looking their best without any risk of damage. Once done, rinse the area with clean water.

Step 3: Pressure Wash If There Are Tough Stains

For areas with more stubborn dirt or algae, it’s time to bring out the pressure washer. Remember, keep it on a low setting to avoid damaging the sandstone.

Carefully go over the surface, focusing on dirty spots but avoiding any forceful direct blasts on the same spot. This will help lift off any tough grime without harming your paving.

Step 4: Deep Clean with Power Washing

If your sandstone is still looking a bit grimy, consider using a power washer with hot water. The heat helps break down tougher stains, allowing for a thorough clean. Like with pressure washing, use a gentle hand to prevent any damage.

Step 5: Soft Washing for a Gentle Finish

If you’ve noticed algae or moss, soft washing can be an effective solution. This method involves using a low-pressure wash and a cleaning solution to gently remove any unwelcome green guests from your sandstone. Apply the solution, let it sit for a while to break down the algae or moss, then gently rinse it off.

Step 7: Drying and Assessing

After cleaning, allow the sandstone to air dry completely. Once dry, take a walk around to assess the area. If there are still some stubborn stains, you might repeat a targeted cleaning method on just those spots.

Preventive Measures and Maintenance for Indian Sandstone

Taking care of your Indian sandstone not only keeps it looking sharp but also extends its life. Here’s how to stay on top of things.

Sealing Indian Sandstone

Sealing your sandstone helps prevent staining from spills, slows down algae and moss growth, and can make cleaning a bit easier.

However, not all sandstone needs sealing, and it’s worth noting that sealing can alter the stone’s appearance slightly, giving it a bit of a sheen. If you decide to seal your sandstone, choose a sealant designed for it and consider the finish – matte or glossy – that you prefer.

Regular Maintenance

• Quick Spills Cleanup: Don’t let spills sit. The quicker you clean up any mess, the less chance it has to stain.
• Regular Cleaning: A gentle wash with soapy water and a brush can work wonders. Doing this regularly can prevent dirt build-up and keep your sandstone looking fresh.
• Tackle Weeds: Keep an eye out for weeds popping up between the stones. Pull them out or use a gentle weed killer to keep them at bay.
• Watch Out for Furniture: Furniture legs can scratch and wear down the sealant on your sandstone. Consider using protective pads under furniture legs to avoid this.

Best Practices for Winter Care and Weather Protection

• Pre-Winter Check: Before the cold sets in, give your sandstone a good clean and check if it needs resealing. This can help protect it against the freeze-thaw cycles that are so common in the UK winter.
• Avoid Salt: If it gets icy, avoid using salt on your sandstone, as it can damage the stone. Opt for sand or grit instead to provide traction without harm.
• Sweep Off Snow: Letting snow sit on sandstone can lead to water seeping in and then freezing, which might cause cracks. A soft broom can be used to gently remove snow without scratching the stone.

FAQs

How do you get black stains out of Indian stone?

To remove black stains from Indian stone, create a mixture of mild detergent and water. Apply this solution to the stains and gently scrub with a soft brush. For tougher stains, you might use a mixture made from baking soda and water, applying it directly to the stain. Let it sit for a few hours, then rinse off with water.

Why is my Indian sandstone going green?

Your Indian sandstone is going green due to algae or moss growth, common in damp and shaded areas.

Regular cleaning, improving drainage, and increasing sunlight exposure can help prevent this. For severe cases, a gentle fungicide or a soft wash cleaning method might be necessary to remove the green discolouration.

Can you use vinegar on Indian sandstone?

No, using vinegar on Indian sandstone is not recommended. Vinegar is acidic and can damage the porous surface of the sandstone, leading to etching and deterioration over time. It’s better to stick with mild detergent solutions or specialized stone cleaning products designed for use on sandstone.

Wrapping Up

This is all about how to clean Indian sandstone in the most effective ways.

Start with sweeping, then use a mix of warm water and mild detergent for scrubbing. For stubborn stains, a low-pressure wash can be effective. Remember to avoid acidic solutions to prevent damage. Ensure regular cleaning and consider sealing your Indian sandstone to protect against stains and weathering. Good luck!
