Can You Pressure Wash Limestone Paving?

Limestone paving can be cleaned with a pressure washer, but we would recommend firstly trying soapy water and a stiff brush. If this does not give you the desired results, then move onto a pressure washer. When cleaning with a pressure washer be careful not to get too close to the surface of the stone as this could damage the surface. After pressure washing you many need to apply an additional coat of sealant that could have been removed by the pressure washing.
