Hey guys
I have just had my very first go with my backpack wfp setup, I'm not to happy with the results as when the water dried on the windows it left a few white runs marks.
Mt TDS is 0 so I know my water is ok, is it likely that dirt has run off the frames and I need to swill the windows off better?
I tried my setup on my own house with leaded windows, do they also cause more problems for wfp.
Cheers, Gary
