Anyone ever Power Washed Granite Stone before .  Picture attached and I have a 200bar, 11hp Petrol Power Washer.

Worth giving them a scrub first with a sutable product to help remove the algae. Should have no problems with the stone as its very hard, just watch out for the mortar joints as these will fly out under pressure.
