I've moved into a new house and the upvc window frames are really dirty. Not from the outside or inside I mean the sides and bits when you have the windows open. They are black with dirt.
I've just spent an hour cleaning one with 3 buckets of water and a steamer. I have 11 more to do.
Is there a company that will come and clean them for you? I'm considering new windows just because they are apparently 20 years old anyway and I cant face 2 days of just cleaning frames.
