I was checking my "Mary Ellen's Helpful Hints" about homemade window washing products, and right there, on the page listing ingredients for such a product she said:
Never wash windows on sunny days. They will dry too fast and show streaks.
YUUBI, I thought. Now I can legitimately put off this onerous task for oh, say a couple of months, til the rainy season, and then , what will be the point with all the rain....
SO many thanks to Mary Ellen and her helpful hints, they saved from doing this hateful job
at least until my inner houseproud person takes over. And that can be a while.
