We use a scraper just the normal ones we use for window cleaning, i think they are the unger soft metal ones, and a brand new blade every time.
It takes less than 10 minutes to do a french door(both pteces of glass), not the easiest method to get it off but it saves using chemicals and possibly damaging the doors or even your hands
Its weird as some houses have had it left on some of the windows and others none, weird

Andy do you not find this leaves scratches any way. I know this method would definitely not work for me in my situation.
Toughened glass, if not tempered and cleaned properly during the tempering process in the factory leaves tiny particles of debris on the surface. Therefore when you rub with a scraper will carry the debris over and scratch the surface..
You can hear the difference of the scraper over the two different surfaces of glass.
There are different types of adhesive used for the plastic and also different grades and price levels. The best type to use is a water based adhesive this is more expensive than the solvent based but will not give the problems. Obviously, when you are not directly involved in the task of removing these products you will not know the problems in removal of the products.
Communication withn site managers and quantity surveyors is sometimes difficult but they tend to listen when you tell them you need more money and what the problem is.
I apply protectorglaze as service to the builders and find it much easier to remove than the plastic. If there is a small amount of residue left it can be removed easily with a standard window clean.

How did you go about removing the leftover protectorglaze?
