I always write it up and my windshields get cleaned right away. The best part is that I am not doing someone else's job. On many occasions I had the cleaners actually thanked me for writing it up. I see that now we have mechanics cleaning windows and I was actually apologetic to the first mechanic that came up to clean the windows. He told me not to worry because the change from aircraft cleaners to mechanic for just this one item actually saved some jobs...He also reminded me of how many mechanics lost their jobs when united switched from mechanics to ramp crew for pushbacks.
