Furthermore, it is just as effective as a concrete cleaner for concrete paving slabs or a natural stone cleaner for sandstone, limestone, slate & travertine patios.

The powerful limestone cleaner & slate cleaner contains a unique blend of cleaning surfactants, specially formulated as a patio cleaning alternative to Sodium Hypochlorite solutions.
