paint on next door's double glazing!

Could be self-cleaning glass, which has what looks like a film and also a slight blue tinge. If so, scraping will wreck it. The only non-scraping solution I can think of is paint stripper but I don't know whether that will damage the film.

Good luck :-)

To test for self-cleaning glass, throw a cup of water over it and compare same with ordinary glass. If self-cleaning the water runs off differently, like a complete sheet, and doesn't leave droplets as with ordinary glass. I don't know whether the self-cleaning process applies to dried on paint.

Thanks for the help people...

I don't think it is self-cleaning because the lady who had it installed (now moved out) used to have a window cleaner round.... unless that was an excuse!!!
