Whats the highest you would use your water (ppm)
around 10ppm i try and change but i have often work at 15ppm and never had any problems
Like mark said 010ppm,
My personal choice I don't use it past 002ppm
I don't go above 002ppm, the standard used in other industries is 005ppm. Spotting can occur after this but a few window cleaners would beg to differ.
I was at a customer this week, non window cleaning and he was showing me spots with water at 014ppm !!!
I have been using my system for 3 months or just over, 350-500 litres a week.. Checked my ppm a few weeks ago and was 001, checked couple days ago and was 000??
