Hi all. I have a ful glass conny roof to clean and been told its self cleaning. Well it looks as if that failed, it looks awful. Also inside looks a but manc, maybe smoker Is there any way to clean a self cleaning conny roof. Persoanlly I think its utter **** and they dont work. I do not want to scratch a coating off, or will that not happen or is it what they like to make you think? I was going to put a cleanign solution on first an spray it on the, then use a hose an brush in one and scrub it clean, then squeegee off, cna a squeegee be uses? This self cleaning **** is throwing a spanner in rthe works, or do you just ingnor that and clean it up. Thank you. Alos any recommended cleaning solutions, cheaper ones. I am using e cover and flash.
