I have just got my poles, but my method must work because I have cleaned my house and the glass is spotless, not a single spot ( using tds 34 tapwater ). I have used what I have learned on the forums but the only problem is that the brush still leaves bits on the glass, just on or two per pane, and on some panes none. I have rinsed the glass as advised many times, but these bits dont want to rinse off, sometimes they will travel down the glass a bit but then stop. But theres no point moving the bits off with the brush because it will be a catch 22 situation, it will leave more bits.
