You should never use anything other that soap and water to clean uPVC
products

They have damaged the surface structure of the upvc by the scouring action
of the cleaner, you should not accept this at all. Your window frame
surfaces will stain and retain dirt and grime much more easily in the
future, and their appearance will downgrade very quickly over the next year
or two. Tell your insurance company that cleaning is not acceptable at all.
If necessary ring several upvc manufacturers and get their advice on the
matter. I am sure they will agree with my comments. In return you can quote
their comments to your insurance company. Do not let your insurance company
bully you, by the sounds of it you need new windows.
