What is the best way to wash windows?

Windows can get build upon them over time and the sun "bakes" the impurities into the pores of the glass. Depending on how long it has been since the window was last cleaned, different scrubbing applications are suggested. Using soapy water and a synthetic bristled brush can scrub deeper and can agitate the window better. A "T" handle and mop cover is the most common scrubber used. There are a variety of different covers available that have different scrubbing power and holds water depending on if you are working on the inside where scrubbing is not needed as much, and less water will drop from the mop. On the outside of the window, there is more dirt so a mop cover that holds more water can be advantageous to the cleaner.
