Clean Yorkstone and Sawn Paving

Yorkstone is sandstone that comes from Yorkshire.  Sandstone in general is a porous natural stone.  There are also a number of different types of imported sawn sandstone, some more porous than others. Porous natural stones can absorb moisture which can cause the stone to go darker in colour.  Stone can be sealed to reduce the effects of porosity but in general a porous natural stone will require more maintenance than a stone which is not porous.  Leaves and vegetation can also stain porous stone. One solution to this problem is lithofin outdoor cleaner which is a chlorine based cleaner specifically designed to remove stains caused by organic material.
