I live in a geodesic dome, situated in a mature oak forest. That means lots of completely unprotected skylights that get filthy with sap, dirt and pollen in very short order. It’s time consuming to scrub, squeegee and then follow up with rags and window cleaner to get rid of all the streaks and soap residue. But recently I had a brilliant idea that I wish I’d had 35 years ago.
Just before a good rain, I did nothing more than used some hot water infused with a squirt of dish soap, scrubbed the glass with a pad, then walked away and let the rain take care of the rest. I figured since rain water is pretty much distilled water, there wouldn’t be any streaks of leftover soap film on the glass. It worked beautifully. And instead of taking me two hours or so the old-fashioned way, I cleaned all seven triangle windows in less than 10 minutes. It will now become my go-to skylight cleaning method from this day forward.
