I have a commercial job to do at 35ft with wfp, the windows have not been cleaned in 18 months and have pollun saps? and very old bird muck, I did try to clean them this weekend but gave up as I could not get rid of these marks. What kind of brush would be best for this as my auto brush does not cut the mustad.

Hi
This may sound crazy but if all else fails why not just secure a light t/bar with a porcupine or pad strip sleeve to the back of the brush with cable ties, give window a good soaking, turn off water, rotate brush 180 degrees and scrub. It may even work better than any brush at that height
