picked up a new custy this week with a large connie out the back, which has had a shading film  stuck on the outside of the windows, never seen this before in 12 years window cleaning, when i cleaned it wfp it did'nt seem dirty at all so was dead easy to clean  anybody else cleaned this before don't want to damage it with me brush

I cleaned a showroom for about 3 years (before losing it  ). They had glare screen fitted to the outside of the upper windows.

Over 3 yrs we scratched the crap out of it. I would suggest being very careful in case you get blamed for scratches.

I was lucky, there was no comeback, but others may see an opportunity to kick up a fuss.
