To begin the clean safely, I carefully went over the entire patio using a surface cleaner. This method allows me to clean the paving thoroughly without damaging or disturbing the joints between the slabs.
Once the heavy algae was lifted, I then used the turbo nozzle to rinse away all the remaining dirt, muck, and organic buildup from the surface.
After the patio was fully cleaned and prepared, it was ready for a sodium hypochlorite treatment to target the remaining black spots and organic staining. Because of the strength of the solution, I applied it carefully by hand using a brush and bucket method. This allowed me to control exactly where the treatment went while ensuring every part of the patio was fully covered properly.
Once the treatment had done its job, everything was thoroughly rinsed down, the furniture was cleaned and placed back into position, and the entire area was left tidy, presentable, and ready to enjoy again.
This pressure washing and exterior cleaning work was carried out in Altrincham, Bowdon, Manchester.
