i have been wondering for a while what the tds is of the water drops that fall from the window above the window you are going to clean, well today i remembered to take my tds meter out with me and tested the water that has come from the top window down the front of the house and the tds reading was 028-030ppm

so will 30ppm mark the windows if not then their is no need to worry

Great idea to measure some drips, but I suspect this will vary from job to job, location etc,
But still an interesting subject, as I believe under 30 ppm will be no visible droplets when dry.

how do you waterfed guys go on cleaning top flats(with the water running down),do you have to do them trad..

i just do the windows if the person that lives under the flat comes out i ask if they need a window cleaner if they complain i tell them it's the same as when it rains they shut up after that or if they keep on i dump the flat and tell them its due to the person down stairs complaining
