To get streak-free windows, mix equal parts water and white vinegar in a bucket. Then, dip a standard mop or a microfiber cloth in the cleaning solution, and wipe down the window's surface. To dry the windows, use a rubber squeegee in straight motions from top to bottom.
One of the ways on how to clean glass windows from outside is to use a window squeegee. An extendable window squeegee allows you to clean high windows from ground level without the need to climb a ladder because they can be extended to several meters.
The best homemade window cleaning solution is to just mix two gallons of water and about a teaspoon of dishwashing liquid together in your bucket. Some people also opt to use vinegar and water to clean windows. In warm weather, you'll get a little more working time by using cool water.
Mix up your window-cleaning solution: In a plastic spray bottle, mix together 2 cups of warm water with 1/4 cup white vinegar and 1/2 teaspoon of Dawn. Sweep away dirt: Using a broom, sweep away the cobwebs and debris from the windows and sills.

If you have smeared windows when you're finished cleaning, you've left cleaning solution, soap, or minerals behind. Whether you have white residue on windows or another blemish, the solution is the same. Clean faster, use cleaner water, and wipe away all your solution, so nothing is left behind.
Hard water and acid rain
Sometimes the minerals and salt that can create ugly oxidation on your windows isn't from the building itself, but rather the water. Windows that get sprayed with sprinklers or ground water can get minerals delivered directly to the glass, where it can streak, spot and stain.
The simplest answer is you should have your windows cleaned once or twice a year in spring and fall. Most professional window washing companies will tell you the same.
And I actually found it to be rather useful. Before getting into it, it's worth pointing out, that window vacuums aren't just for clearing condensation on windows, they also good for sucking up spills on glass and streak-free window cleaning as they have a squeegee head and onboard tank.

Removes dirt more easily – hot water is more successful in removing dirt. This is because hot temperatures make dirt particles vibrate faster, which makes it a lot easier to wipe them away.
Window Washing Tips
If you want to take an environmentally friendly route (which we recommend), then a solution of warm water and vinegar will do the trick and get your windows clean. Some brands and types of windows are much easier to clean than others.
“Vinegar is a good cleaner because it's acidic, but when you add dishwashing liquid/dish soap to it (which is a base or neutral) - you neutralise the vinegar. You take away the very thing that makes it work well. “The dishwashing liquid works that well on its own. Adding the vinegar is a pointless step.”
Spray a stronger mix of 1:1 water and vinegar (or Windex, or glass cleaner) at your window, so that the solution covers most of the glass. (I found Windex to work better, but if you have pets—or kids—who frequently lick outdoor windows, vinegar may be the best route for you.)
Distilled vinegar and hot water
A true tried and tested method, distilled vinegar and hot water has proven to be one of the most successful methods to clean your windows. Since vinegar has an acidic composition, it's quick in breaking down the thin film of grime that collects on the glass' surface.

For most windows, combine equal parts distilled water and white vinegar. In most cases, it's best to do this in a spray bottle, but for larger windows combine more liquid in a bucket. For very dirty windows, especially exterior windows, combine 2 cups of water, 1/4 cup of vinegar, and 1/2 tsp of dish detergent.
Dish Soap and Water
Dish soap is perfect for cleaning windows with residue and buildup, and you only need a few drops of dish soap to get the job done. If you're cleaning inside windows, use a spray bottle and if you're washing exterior windows, use a bucket.
