Where the wall was rollered we have paint splatters on the glass. Its in a conservatory and its 7 years old!!!
I think they may have baked on in the sun!
Its annoyed me for all this time and tonight I tried to get them off with a non abrasive sponge/scrubber thing and it wouldnt touch it. Im too worried about scratching the glass to try anything else.
Even with a thumbnail its quite difficult to get off
