Although the most popular and easiest way to clean windows is with a commercial cleaner, you have other, more natural options that can save you a great deal of money.
Make a solution of ½ teaspoon of liquid soap, ¼ cup vinegar (white), and 2 cups water, and mix it in a spray bottle. This combination will be streak-free and will take off the residue left by other cleaners. Spray on and wipe off with a lint-free cloth or squeegee.
For regular window cleaning, skip the soap after the first application. Stick with a cup of vinegar and a cup of water. If you have trouble spots or excessively dirty windows, heat up the vinegar alone and use it full-strength.
Ammonia is the main ingredient used in most commercial window cleaners, and it can be more effective than vinegar. For an ammonia-based solution, use 1 tablespoon for every gallon of water. As above, mix the cleaner in a spray bottle for easy application and wipe away with a cloth.
With this ingredient, you will have a scrubber and a cleanser all in one! Squeeze a lemon and remove all seeds. Then press the skin directly to the window and rub circles around smudges. Work in small areas and follow with a cloth to dry.
Rubbing Alcohol for Small Projects
If you have a small window area or a really dirty area, try rubbing alcohol straight out of the bottle. Apply to a lint-free cloth for the best results.
This method is not recommended for larger windows because it would not only take a long time but could become expensive. Keep in mind, however, that rubbing alcohol works well when removing paint splatters from windows and mirrors.
Utilizing homemade window cleaners is not only good for the environment but can also save you money in the long run. If one doesn't work, try adjusting the ratios of the ingredients to meet your needs. Dirty windows may call for less water and more of the cleaning substance, though regularly maintained windows should be fine with a solution diluted with more water.
