Cuban mop - "I don't buy disposables. I have a basket full of old kitchen and hand towels for cleaning. Just drop the cloth on the floor and flip it over the bar mop and I'm set to clean. Wash, rinse, repeat, then toss in the washer. The best mop! Good for outside window washing too."
DYI outside window wash: 1/2 bottle of Jet Dry (dishwasher rinse). 4 Tblsp. rubbing alcohol. 1/4 cup ammonia. 1 handful of powdered dish-washer detergent. 2 gal. of hot water. Mix all together and use on outside windows.
