. . . Rubbing alcohol, that is. If you're mixing your own green cleaning products, you might find yourself slightly dissatisfied with the simple vinegar-and-water mix you're using for cleaning windows. The New York Times recently tested different window cleaning products, including mixing up some simple vinegar-and-water solutions. The tester, Stephen Treffinger, reports, "I tried several variations of a homemade white-vinegar-and-water mix, which did a good job at practically no cost. The one that proved most effective was one part vinegar to two parts of water. It was very runny, though, which meant I had to wipe quickly and vigorously with newspaper. A couple of tablespoons of rubbing alcohol added to the mix boosted its cleaning power and made it evaporate faster."

So, next time you mix up your own window washing solution, add a shot of rubbing alcohol to really add some oomph to your homemade window cleaning product.
