Cleaning block paving is a fairly straightforward task, although you’ll want to be careful to not use any chemicals that may cause damage to the surface. Use a simple household soap, mixed with water, and brush this across the paving with a stiff brush. Then, simply rinse off with clean water. Alternatively, use a pressure washer – but be careful not to use it on a powerful setting, as this may damage the joints and can cause slabs to come loose. Using the pressure washer on a medium setting and at a 45 degree angle is recommended.
Dunbeath
Dunbeath is a village in south-east Caithness, Scotland on the A9 road. It was the birth place of Neil M. Gunn (1891-1973), writer of The Silver Darlings, Highland River and so on, a number of whose novels are embeded in Dunbeath as well as its Strath. Dunbeath has a really abundant historical landscape, the site of various Iron Age brochs as well as a very early medieval reclusive site (see Alex Morrison's archaeological study, "Dunbeath: A Cultural Landscape".) Of Dunbeath's landscape, Gunn composed: "These small straths, like the Strath of Dunbeath, have this intimate appeal. In boyhood we learn more about every square lawn of it. We encompass it physically as well as our memories hold it. Birches, hazel trees for nutting, swimming pools with trout and a periodically noticeable salmon, river-flats with the wind on the bracken and also vanishing rabbit scuts, a wealth of wild flower and tiny bird life, the soaring hawk, the unforeseen roe, the old graveyard, thoughts of the people who as soon as lived far inland in straths as well as hollows, the past as well as today kept in a minute of day-dream." ('My Little Bit Of Britain', 1941.). There is a neighborhood museum/landscape interpretation centre at the old town college.
