Whats the best thing for cleaning these flagstones that won't damage the grass if it overspills onto the lawn?
They are a bit damp at the moment, because my wife has jet washed them a few hours ago, but when they are dry they have black marks and are not a fairly uniform colour. The ones to the right in the second picture are two rows of a Cotswold stone type of colour, and much softer, whereas the main area is grey concrete type.
