1. Prepare the slabs and patio first

Make sure you are equipped with all your protective clothing ready to go and then you can start clearing any larger bits of debris that may be lose and sitting on the surface of your sandstone.

You may even want to vacuum smaller debris up if possible, as this will save you time and effort and make the cleaning job easier.

2. Prepare the cleaning solution

Next you will need to prepare your Indian sandstone cleaning solution before use. This needs to be diluted prior to use in equal parts of a 1:1 ratio.

This is one-part cleaner to one-part water. This mixture should be placed into a bottle pump sprayer or a watering can if need be.

For whatever reason you do not possess either of these items, it is possible to pour directly from the product container, ensuring it remains wet on the surface at all times.

3. Apply the cleaning solution

Now it is time to apply your solution. Before doing so, make sure there are no sensitive materials or fabrics nearby. This solution can cause discolouring to delicate materials, hence the protective clothing.

Then apply your mixture as generously as you need to the Indian sandstone area.

Be sure to cover the entire area, and you must keep it wet. This mixture cannot be left to dry out and needs to maintain its moisture during its 60-minute active session.

If it is a warm day, lightly mist additional product onto the existing product if it looks as it it’s drying.

The cleaning formula needs a good 60 minutes of dwell time to activate.

4. Use a scrub or broom on stubborn stains

If you feel some areas are more stubborn than others, then apply pressure and scrub using a brush or broom. For the best results you are able to leave this product on for longer, but it is recommended to try and stick to no more than four hours.

If you want to test on a small patch of a stubborn stain, you can do so by leaving overnight to see the potential outcome.

5. Neutralise the Cleaning Solution with water

After you are happy with how it is looking; it is now ready to neutralise the product using clean water. This can be done with a hose or watering can.

If your Indian sandstone is in direct contact with grass, try and avoid getting the product on it or add additional water to dilute even further.

As this formula kills vegetation, you want to avoid it coming into contact with your grass.

6. Rinse down the Indian sandstone with a hose or pressure washer

The final step is to use a power washer or hose on a high setting to clean the remainder off.

This will leave your Indian sandstone very clean and looking as good as new.

What causes patio stains?

Before you get started off with cleaning your Indian sandstone patio or slabs, it’s always handy to know what is causing your discoloration. This will help you better understand why ours is the best cleaner on the market.

After all, knowledge is power!

It should be noted that when it comes to Indian sandstone, it is always best to use an appropriate cleaner as it has the ability to discolour and change in texture. If you use the wrong product, this could ruin your precious paving.

Even though it is a great stone to use, it is still prone to dirt build ups.

The most common cause of stains on stone is Lichen. Lichen is those little black marks the you may spot from time to time on your slabs. Lichen are spores of dust which grow under leaves, plants and trees, which are then transported via the wind to land on your patio.

Once they settle, they leave a stubborn black stain behind.

If bleach is attempted to remove the Lichen, it will cause more harm than good. This could potentially strip the colour of your Indian sandstone, and not even remove the lichen.

Lichen needs to be scrubbed off with a brush, or now you can use Universeal’s New Clean 60 Patio Cleaner to assist you with the job.

Other commons stains include moss and algae. These again can be removed using harsher chemicals, but not using the correct one will damage your paving slabs.

This is why it is so important to use the right products for the job that will clean Indian Sandstone effectively, not leading to any damage.
