New build clean - paint spots on glass after frame rinse

[DeLaCruz]

After cleaning a new build UPVC frame I noticed a couple tiny white spots on the glass below, after repeated rinsing and agitating the spots won’t come off, like they’re stuck on the glass. I did scrap one off with the brush head gently - have you guys encountered this problem. What’s the best way to get rid of these spots ? Thanks again for the good advice

Thanks but window was second floor so no go for that one - tbh I don’t mind if these are already on the glass - it appears they are little bits from the top of the frame that have stuck on their way washing down the glass, I mean I would expect them to just come off with the brush but they’re stubborn as hell once they stick

I wouldn't expect white spots on the glass after cleaning a UPVC frame. Have you any idea what these white spots are?

One thing you could try is this:

Sounds like its paint that has splashed on the glass  and then dried , unless it’s a builders clean I wouldn’t worry about it
