Cleaning windows can be a challenging task, especially when you have to deal with stubborn dirt and grime. However, using a pressure washer can make the job a lot easier and more efficient. In this article, we will guide you through the process of using a pressure washer to clean your windows.

Before you begin, it’s essential to understand the benefits and potential risks of using a pressure washer to clean your windows. Pressure washers are powerful tools that can easily damage windows if not used correctly. That said, when used properly, they can clean windows quickly and effectively.

Preparing for the Task

The first step in cleaning your windows with a pressure washer is to prepare your equipment. Make sure that your pressure washer is in good condition and has the appropriate pressure setting for the task. Using a pressure washer with too much pressure can crack or shatter your windows, while using a pressure washer with too little pressure will not clean your windows effectively.

Next, you’ll need to choose the right nozzle for the job. The ideal nozzle for cleaning windows is a 25-degree fan nozzle, as it provides the right amount of pressure and coverage. You can also use a soap nozzle to apply a cleaning solution to the windows before washing them with the fan nozzle.

If you’re working on a second or third-story window, it’s best to use an extension wand to reach the higher areas. You can also use a ladder, but it’s essential to have someone hold the ladder steady while you work.

Cleaning the Windows

Now that you’ve prepared your equipment, it’s time to start cleaning your windows. Follow these steps to ensure that you clean your windows effectively and safely:

Step 1: Remove any loose dirt and debris from the windows using a soft-bristled brush or broom. This will prevent the pressure washer from pushing dirt and debris further into the window’s surface.

Step 2: Apply a cleaning solution to the windows using a soap nozzle. Allow the solution to sit for a few minutes, then switch to the fan nozzle and wash the windows from top to bottom. Make sure to work in small sections to avoid the solution from drying on the windows.

Step 3: Rinse the windows thoroughly with the fan nozzle, again working from top to bottom. Make sure to remove all of the cleaning solution and dirt from the windows.

Step 4: If necessary, repeat the cleaning process to remove any stubborn dirt or grime. However, be careful not to use too much pressure, as this can damage the windows.

Step 5: Dry the windows using a squeegee or a soft cloth. Make sure to remove all of the water to prevent streaking.

Tips for a Successful Clean

Here are a few additional tips to help you achieve the best results when cleaning your windows with a pressure washer:

  • Always wear protective eyewear and gloves to avoid injury.
  • Test the pressure washer on a small, inconspicuous area of the window before starting the cleaning process to ensure that it does not cause damage.
  • Use a cleaning solution that is safe for your windows and will not leave any streaks or residue.
  • Work in the shade or on a cloudy day to prevent the cleaning solution from drying too quickly.
  • If you’re using an extension wand, make sure that it’s securely attached to the pressure washer and the nozzle.


Cleaning your windows with a pressure washer can be a quick and efficient way to achieve sparkling clean windows. However, it’s essential to understand the potential risks and to take the necessary precautions to avoid damage to your windows or injury to yourself. By following the steps and tips outlined in this article, you can clean your windows safely and effectively, leaving them looking like new.
