First job this morning was a commercial building, and decided to WFP it for the first time. THE RESULTS WERE SHOCKING TO SAY THE LEAST. I was in direct sunlight at 7.30am. My TDS reading is at 011, which im aware is not ideal. The flow was relativly slow but I gave them a good clean and rinse.
Once dry, the windows were covered in spots and streaky all over, so got the trad gear out but even then I couldnt shift it. Something is not right. Ive spoke to the owners and said i will try and find a solution, and get the windows back to normal.
The picture below is some of the windows that ive ruined, but you cant see the spots/streaks.
Help
