Hi, just picked up a new commercial job and just wondered if anyone had any ideas on how to get rid of limescale runs on glass. The new job I have has got stone surroundings which has caused limescale to run down glass when it has rained etc. Your thoughts will be greatly appreciated...

A bit of Viakal (get it from any supermarket) wiped on and left for a minute does the job, unless it has got right into the glass.

Its called "washdown" at least thats what we call it and if its been on there any length of time it will mark the glass.
The good news is any shower limescale remover such as Cillit Bang for lime should get it off.
When they put the windows in they should have put a lip (or "skirt" to give it its proper name) above the window to deflect rainwater from running off the masonery straight onto the glass. Its also called a drip lip
Its very common with new houses and extensions to find the windows aren't skirted. Its just shoddy workmanship by the builders who can't be bothered and it will always cause problems with washdown.
Washdown can also be a problem when you are cleaning with a wfp. Your water will be running down from the windows above and if the window below is unskirted its going to run straight down that as well. This means you can't really clean the downstairs window until the water has stopped running down from above and that could be a long time.
Thats one of the many causes of mysterious white spots on the glass.
