After 14 months I am still steadily loosing customers due to spotting being left on the windows after the drying process is completed. My water is running at zero I also live in a soft water area .My work is 90% estate based so not working on exceptionally dirty main roads. It is very frustrating that some windows are completely spotless yet many other windows still produce spotting even though my water reads zero . All the frames have now been fully cleaned after 14 months of pole cleaning . Any suggestions on what is going wrong?</blockquote>
