Hydro-Tek External Cleaners doing a free clean for our local church St Mary's Church built-in 1875 so we have to be careful as it's a listed building, so we used chemical treated on theses steps, and then used the white tip as not to damage the stone in any way,  after we used a biocide to remove any black spot and we will keep checking on progress as time goes by, we also cleaned the front of the church and a small wall and treated them also to a biocide treatment,  all free of charge and we enjoyed doing it  for our local people,  looks so much better now and we have offered to keep it clean free of charge.. thanks for watching..more to come from this church as it needs cleaning..
