Using a pressure washer to clean windows is a quick and effective way to wash away dirt and other debris from your window. However, the cleaner must exercise extreme caution and take a few things into consideration before they start washing. This article outlines these considerations, gives a step-by-step guide on how to clean windows, and recommends the best cleaning detergent to pair with your pressure or power washer.

What to Do Before You Clean

Before cleaning, you’ll need to check the condition of your windows. This includes ensuring that:

• The windows have no visible cracks
• The windows are securely fastened
• The glazing is solid and intact
• The caulking or other stripping is in good condition
• All screens are removed
• The frame is aluminum or vinyl instead of wooden 

It’s important to make sure that your window and its surrounding parts are undamaged and able to withstand high-pressure blasts. If not, serious damage may occur.

Once you’ve checked the condition of your surface and have deemed it fit for a power wash, begin taking the necessary safety precautions, especially if you plan on using a cleaning solution. Make sure to:

• Wear goggles
• Wear gloves and other protective clothing if the detergent is toxic
• Cover landscaping in the surrounding area
• Put distance between the target area and you 

How to Clean Windows With a Pressure Washer

After you’ve performed the necessary checks and preparations, follow these simple steps to achieve the best cleaning.

Step 1: Start with Water

Begin by turning your high-pressure washer to a setting of 1,200 PSI. Spray the water from top to bottom, wetting the surface and getting rid of any cobwebs, bugs, and other stray debris. This step will prepare the surface for the soap. Never go over 2,000 PSI and keep a good distance between yourself and the window.

Step 2: Add Soap

In order to see the best results, add a high-quality detergent to your pressure washer to help lift up the dirt and grime stuck to your windows and the surrounding surfaces. Make sure you spray in a horizontal motion rather than a vertical one.

Step 3: Rinse

Once you’ve removed all the dirt and debris, use water and a lower PSI setting to rinse off the soap. Start your rinse from the top and move downwards. Never let the soap dry on your window.
