What is the best way to clean windows?

There is more than one effective way to clean your windows. One inexpensive method is to start by making your own cleaning solution by adding warm water and a teaspoon of dishwashing soap to a 5-gallon bucket. Scrub the window with a scrubber or clean sponge that is damp with washing solution. Then, starting at the top, wipe off the solution with a lint-free cloth or a squeegee. If using a cloth, try to have only dry areas contacting the window at each pass. For the best results, wash the windows when they are not getting direct sunlight.
