Power washing is a great way to get streak-free windows, but you have to use the right technique. It’s also helpful to have the right equipment on hand.

A squeegee is a useful tool for window cleaning, and if you have one, it’s important to know how to use it.

Squeegees work by applying a spray of water to the glass and then pulling the blade in an S-shaped motion. This helps prevent streaks from developing when the squeegee is dry, says Fisk.

It’s also important to remember to apply the spray from the top of the glass down, so that it doesn’t drip onto other areas. Skipping this step will cause streaks to form.

To get streak-free results, use a quality detergent and a squeegee. Make sure to follow the manufacturer’s directions and pick a soap that is power-washer safe and recommended for windows (find these in your local hardware store).

Start with the top of the window. Then move down in an angled motion and back and forth to remove dirt and grime from the exterior. Once the dirt is gone, rinse the entire window thoroughly with clean water.

Then, wipe the window down using a microfiber cloth or chamois to remove any excess liquid. Repeat on the other side of the window to remove any splatters.

Another trick for getting streak-free results is to use a squeegee and dry the window with a microfiber towel. Paper towels can leave lint streaks on windows, but a squeegee and a microfiber cloth will give you a pristine finish.

If you want to save money on window cleaning, try making your own homemade cleaner. You can find the ingredients in most household stores, including home improvement centers.

Several different types of chemicals can be used to clean glass, including dish soap, detergent, Trisodium Phosphate and etching salt. It’s also common to add an anti-freezing agent in the winter, especially when the temperature is low.

Some people will also use an electric pressure washer, which uses a hose and a high-powered pump to spray water on the window. This method is effective for cleaning mildew and moss off of exterior surfaces, as well as dirt and debris from windows and siding. You can also rent a power washer from a contractor or rental store for larger jobs.
