My guys cleaned a roof and some of the over spray got on windows. It was southeast exposure and I'm guessing they didn't keep it rinsed well, and there was spotting. They went back and sprayed with bleach wash, then scrubbed with soft bristle siding brush and rinsed. There is still some streaking. Any suggestions for cleaning? I am quoting her a new door, so I need to make it look good.

Mix a mild acid solution or on the other side of the PH scale a light base solution like vinigar and water. spray on and buff out. see if that works. rinse, rinse, rinse and do a bleach wash and rinse.
Its the worst when you have customers whom have screens on the outside of the windows so if you do streak the windows you cant even scrub them. plus most of the screens you cant remove from the out side. we have been lucky to not have that problem too much this year. did happen a lot in the past.
