I have done quite a lot of conservatory roof cleans this week and a have been using the new vikan mono filament brush, but it still has trouble moving the moss and algee from the conservatory roofs.Do you fine gentlemen use a stiffer brush for this kind of work and if so were did you get them from, on the same subject i have heard of a white scourer pad that can be used without scratching the soft plastic on conservatory roofs.
