How to clean stone slabs?

1. Maintenance and cleaning of garden slabs

Before moving on to tips and tricks against stubborn stains, it is important to take the time to clean and maintain the terrace tiles regularly.

Here are some tips for regular maintenance and cleaning of slabs and stones:

• Act quickly to prevent stains, mold and moss from becoming embedded in the slabs and stones.
• Regularly clean the tiles with soapy water and a push broom, quite simply.
• You can also use a cleaning product specially designed for outdoor slabs and floors.
• Use a pressure washer occasionally for deeper cleaning.

2. Clean cast stone slabs

If the garden flagstones are made of cast stones then a natural solution to cleaning them is to use baking soda.

Quick and easy, here’s how:

1. Add 1 cup of baking soda to 1 liter of warm water and mix well.
2. Use a push broom and scrub the garden flagstones to thoroughly clean them and remove stains.
3. Rinse with water to finish and repeat as needed on stubborn stains that are still visible.

You can also replace the baking soda with soda crystals which will also be effective for cleaning blackened terrace slabs.

3. Clean concrete patio slabs

If you have concrete patio slabs or made from a concrete mix the pressure washer should suffice for thorough cleaning.

However, if the concrete slabs are blackened, black soap can be very effective. Here’s how:

1. Mix liquid black soap in a bucket of warm water and stir well.
2. Use a push broom and scrub the blackened slabs and stones.
3. Finish with a high-pressure cleaning to thoroughly clean the deck.

You can also scrub stubborn stains on concrete with a mixture of water and glycerine. Very effective!

If the slabs of the terrace are blackened and you are looking for a solution to clean and whiten the terrace then percarbonate of soda is an excellent product!

1. Add 4 tablespoons of percarbonate of soda to a bucket of warm water.
2. Mix and use a push broom to clean and scrub the slabs and stones of the terrace.
3. Insist on the blackened spots and rinse with water to complete the wash.

You can use this stuff for cleaning natural stones, concrete slabs and even on tile and marble.

5. Clean gravel tiles gently

Gravel slabs are very popular, but require special care in terms of their maintenance and cleaning.

Indeed, this type of slabs must be cleaned gently, but all the same with firmness to properly remove encrusted stains.

1. Use a soft-bristled brush with a mixture of water and liquid black soap.
2. Rub the gravel slabs to remove stains and restore the natural color to the slabs.
3. Rinse with a jet of water (not too strong the jet of water) to complete the cleaning.

To remove stubborn stains on gravel tiles, you can also use an old toothbrush with white paste toothpaste before rinsing with water.
