The area I work is just under 300tds and some customers have been watering hanging baskets and splashing windows.....what a mess it leaves behind!
A customer was rinsing his car yesterday and when it dried it was a white,chalky mess!so I rinsed his car windows for him.....
Another chap(out of work barber)has been cleaning some of my customers conny roofs and fascias and then rinsed the windows leaving them with hard water stains.....
......
The area I work has only been a hard water area for the last 12 months or so.....
What will get these marks off?Unger rub out,?winsol?bronze wool?
