It might be challenging to clean patio paving slabs if you are not using the right patio cleaner. Naturally occurring stone patios can be particularly difficult to clean since the surface of sandstone or limestone paving provides an ideal environment for the growth of mould, algae, and moss. If you want your block-paved patio or paving slabs to seem like new, you must use an efficient patio cleaning. Our product easily and safely removes green spotting thanks to its unique active ingredient.
