Bronze wool pads will help mate...you can get them online or from b and q but personally I wouldn't bother myself.

I'm a window cleaner who removes dirt,dust,bird muck,green algae,etc but I draw the line at hard water marks on glass.cant be bothered!

Lemon juice or vinegar, you need an acidic solution scrubbed on.

Sulfamic Acid is a great descaler less aggressive than brick acid (hydrochloric acid) but I've never used it on glass.
Sometimes it's better to say can't do anything about it.
I had a mate Windie who had one of the easiest rounds, short ladder, stock response "Can't reach that one!"

In the early days - I would want to clear up all these non standard type stains - hard water stains, limescale, etc...

but as you go on you realise
1, most customers while thankful at the time rarely have any more loyalty than if you hadn't of bothered
2. These things always take more time than they are worth
3. As a business why waste time with this when you could have knocked out 6 standard cleans for more more, less hassle

I only wash clean windows . If it doesn’t  come off with pure water and a brush , it stays on .

You only wash clean windows? Are you not a window cleaner then? Some insect 💩 won't come off with pure and a brush.

Then it stays on .

I have a bottle of viakal in the van for hard water spots. Couple squirts on the brush clears most stuff up.
