1. Determine the Issue
Before you start the cleaning process, it's important to identify the specific issues with your sandstone paving. Different problems require different solutions. Here are some common problems and their causes:
• Everyday dirt and grime:
This is the result of regular use and can be easily rectified.
• Algae growth:
Green fuzz covering the entire slab is usually caused by algae.
• Moss:
Green borders between the slabs are a result of moss growth.
• Lichen:
Patches that get larger over time are caused by lichen, which is a combination of fungus and algae and/or cyanobacteria. Lichen can be the most challenging issue to deal with.
2. Selecting the Right Solution
To clean Indian sandstone, it's important to choose the right cleaning solution. Avoid using acid-based products or solutions that contain iron, as they can cause rust and discoloration. Harsh chemicals can also permanently damage the sandstone. Fortunately, you don't need fancy potions to clean Indian sandstone paving slabs. Here are the recommended solutions:
• Everyday grime:
Soapy water (washing-up liquid) is the simplest and safest remedy.
• Algae, moss, and lichens:
Use a patio cleaner (always read manufacturers application guideline prior to use).
3. Preparing the Cleaning Mixture
Once you have chosen the right solution, it's time to prepare the cleaning mixture. For soapy water, add enough soap to make the mixture frothy. For patio cleaners this will vary depending on the brand and the type of sandstone paving patio clear used. Make sure to wear protective gloves and goggles when handling liquid based patio cleaning solutions.
In order to give the chemicals ample time to dislodge surface dirt, let it sit for 20 to 30 minutes if using soap water (longer is better for more severe buildups) and if using a patio cleaner this will vary, therefore, it is important to read the manufactures technical data sheet.
4. Applying the Mixture to the Sandstone
Before applying the cleaning mixture, remove any nearby furniture and sweep the affected area. Then, pour the mixture onto the sandstone slabs, ensuring thorough coverage. Let it sit for 15-30 minutes, or longer for more depending on the manufacturers recommendation to remove stubborn stains and build-ups.
5. Scrubbing and Brushing the Stone
After the mixture has had enough time to loosen the dirt and stains, it's time to scrub and brush the sandstone paving stone. Use a stiff brush or broom to scrub the surface, paying special attention to corners, gaps, and borders. For lichen removal, a wire brush may be necessary. Be careful not to apply too much pressure, as it can damage the sandstone.
6. Rinsing and Removing the Dirt
Wash away the loosened dirt and cleaning mixture with clean water. You can use a bucket, watering can, or a hose with low pressure. In most cases, this step will complete the cleaning process. Though you might need to repeat the previous methods two to three times over a number of weeks if the stains and buildups are really difficult to remove.
7. Power Washing (Optional)
A power washer might be useful if you need to clean a sizable area of sandstone. Be careful though, as sandstone is relatively soft, and a strong torrent could erode the stone and the impurities as well. Instead of washing parallel to the joints, use a low pressure setting and wash diagonally across the slabs. If necessary, repeat the procedure to ensure thorough cleaning.
8. Preventative Measures for Future Maintenance
It's crucial to take preventive action to stop infections and buildups from occurring in the future. Here are some steps you can take to avoid problems:
• Brush your sandstone frequently to remove dirt, weeds, and germs before they get a foothold.
• To protect the jointing and stop moss, algae, and fungi from growing, use a high-quality sealer.
• Take into account shifting plants and removing surrounding water features that may cause moisture to accumulate.
• Perform the cleaning procedure once more every two to three months, even if there is no visible dirt, to identify any invisible hazards as soon as possible.
