This was a very dirty cobble paved driveway that was in desperate need for a deep clean. The customers said it became very slippery when it rained and was apparent to me as soon as I started cleaning once the surface was wet.
After a good going over and a thorough rinse of all areas, it was free of Algae, Moss, Weeds, Black Spot Lichen, general dirt and grime. We were delighted with the result as was our customer.
