Pressure washers can be used to clean more than just the sides of buildings and concrete driveways. With some adjustment they also can be used to effectively clean windows. There are several cleaning solution options that can be made at home to use in a pressure washer. Each option works best for a slightly different window cleaning task.
Cleaning Solution Options
Pressure washing formulas can be expensive when purchased at a cleaning supply store. In addition to that, in many cases, the units sold for pressure washers are designed for professional users, and the amount sold is much more than could be used for home use. Water will often be enough to clean most windows if a squeegee is applied afterward to eliminate streaking. Another option is to mix a small amount of soap into the water to eliminate greasy grime from extremely dirty windows. The last homemade cleaning option is a mixture of ammonia and water. The ammonia helps the water dry faster, eliminating streaks.
The easiest solution to create is the soap-and-water mixture. For each gallon of water, mix in about ½ tsp. of grease-fighting dish soap. Mix a little, but do not over-stir or huge bubbles will form. When spraying the soap onto the window the mixture will create suds. Rinse with plain water after use to prevent dirt from sticking to the soap scum. An ammonia mixture is easy to make as well. Mix in about ½ cup of ammonia in a gallon of water. Add in 1 pint of rubbing alcohol to the mixture. This formula is fast drying and works well with windows that will not use a squeegee. If you have windows that are not very dirty, or that are beyond hand reach, this formula will work best.
Take the proper safety precautions when pressure washing windows. Adjust the pressure to where it is safe to use on windows. Make sure before using any pressure washer on a window that the manufacturer of the machine has issued a statement that it is safe for window use. Never spray a power washer at yourself or other people. Also keep the spray away from delicate objects and animals. Never operate the machine from inside a building. Wear appropriate clothing such as long pants, sturdy shoes and protective eye wear.
