Why Did the Highest Windows Have the Worst Hard Water Buildup on This Condo Job?
Just wrapped up a window washing job at a condo, and the higher windows actually had the worst hard water buildup, more than I expected.
My cleaning solution took care of most of it. For the truly stubborn spots, I broke out the window scraper and steel wool. Every window came out crystal clear in the end.

Hard water buildup isn’t always worst where you’d guess. Don’t assume the windows you can reach from the ground are the only ones that need real attention. The higher ones, further from easy reach and regular cleaning, can end up hiding the toughest spots.
