Calcium stains on windows

We have calcium stains on the windows from the sprinkler when watering the lawns. They are hard to remove does anybody have a magic answer to fix this?

Even if you remove them, the sprinkler will cause them to return. You would need to move the sprinkler for starters. C-Thru is a good product but does require time and effort.

Yes Brasso removes them but you will have to stop further damage

We got them on a glass topped outdoor table and removed them with the cutting compound you use on car paintwork.

C-Thru glass cleaner from Mitre 10 is the best product I have found. I had very badly marked windows and shower glass which are now completely mark free. It was alot of work though, but good exercise for your arms :)
