Spotting on window / mineral marks?

[Edward Baskerville]

Hi guys, been cleaning this house for 4 years now and the back kitchen window seems to have mineral marks on the glass when it drys. I tried unger rub out on the soft side of a pad to remove but unfortunately didn't work. I was looking to possibly use bronze wire wool to tackle the job next.. just thought ask any you guys out there for advice before I proceed.  Sorry if the photos aren't great it was nightmare to get accurate shot.

I assume you can feel the marks on the glass and they are not just the sealed unit has failed?

Try vikal if it’s lime marks .

Lime deposit, hard to remove with standard methods. I get alot of it on first clean Velux windows and Vikal works really well if you spray it and leave for a while then come back with bronze wool or worn green scouring pad

Get down to poundland and grab a few spray bottles

Most of what I see is cement, Velux windows mainly and I think it’s from cement holding down ridge tiles and chimney pointing.

Don't see a great deal of it here as you mentioned it’s Devon, soft water central
