It becomes necessary to learn how to clean sandstone paving due to the issues such as moss, algae and dirt that make your patio or pathway dirty. The problem usually happens in places that lack sunlight and stay wet, especially during rainy or cold seasons.
The first stage of cleaning includes sweeping with an outdoor brush. All leaves, dirt and other impurities will be removed from the slabs and joints, thus lowering moisture and preparing for further cleaning.
Next, rinse the paving with warm water and clean it gently moving the brush in a circular way. Do not use a metal brush because it may damage sandstone paving and its natural surface.
In case of green moss, black patches or algae growing on the surface, apply a special product. For instance, ProJoint Black Spot & Algae Remover produced by East Yorkshire Stone can assist in eliminating those growths from the surface. It can prevent further growth of moss if applied at an early stage.
Finally, keep the sandstone paving clean by regularly sweeping and quickly removing stains from it. You should pay extra attention to places under the trees because they get dirty quicker.
