How to clean ingrained dirt from old window?!
Discussion
I have a dormer window on my house which I believe is quite old, house is 1860 so anywhere up to then!
The glass in the windows is almost like it has a frosting on it / looks cloudy on the outside. It is the windows at the side of the dormer which are the issue as they are not accessible unless actually on the roof (We have scaffolding up currently so I dont think they would have been cleaned for decades!!
Can see through it but not very well. I have tried various cleaning fluids but no luck cleaning it up. The only area i have managed to clear it (in a very small patch) was using a stanley blade but this was very hard work.
Anyone had a similar situation and got ideas of things to try? SO far I have tried the following:
Polish
Water
Window Cleaner
Brake Cleaner
White Spirit
IPA
Thinking I need something abrasive to help shift it, has anyone tried wire wool or fine sandpaper on a window?!
