I've got a job coming up in a few days to clean a glass-roofed conservatory inside and out. The glass is this self-cleaning variety. As the panels are probably double glazed, the inside probably isn't self cleaning.
Doing the outside and inside upright panes are no problem, it's cleaning the inside of the roof.
I guess that it's a mop and squeegee job. Is that right? Is there a special technique for squeegeeing a sloping panel with a standard squeegee?
