Spring is in the air, and with it comes the annual tradition of spring cleaning. Many homeowners look to power washing as a quick and efficient way to clean the exterior of their homes. However, when it comes to windows, using a pressure washer can be a double-edged sword. While it can remove dirt and grime, it can also cause significant damage if not done correctly. Let’s explore the risks associated with power washing windows and the best practices to ensure your windows remain intact and sparkling clean.

Risks of Power Washing Windows

 

Potential Damage to Window Frames and Glass

Using a pressure washer on windows can cause several issues, especially if the windows are not in perfect condition. For instance:

  • Chipped or Peeling Paint: If the paint on your window frames is chipped or peeling, the high pressure from the washer can strip off more paint and expose the wood underneath, leading to potential water damage 1.
  • Weak Glazing: The glazing between the frame and the glass must be intact. High pressure can break this glazing, resulting in shattered glass 1.
  • Double-Paned Windows: The seals on double-paned windows can break under high pressure, allowing moisture to enter and causing fogging between the glass layers 1.

Experience Matters

Even if your windows are in good condition, the experience of the person using the pressure washer plays a crucial role:

  • Proper PSI: It’s essential to use a PSI of no more than 2,000 to avoid shattering the glass. Additionally, the spray must be adjusted to its widest angle (40-65 degrees) and applied at a shallow angle (no steeper than 30 degrees) to avoid direct perpendicular pressure 1.
  • Correct Cleaning Solution: The right ratio of cleaning solution to water is necessary to avoid leaving a filmy residue or not cleaning the windows effectively 1.

Collateral Damage

Power washing can inadvertently cause damage to other parts of your home:

  • Water Intrusion: High-pressure streams can shoot water underneath siding or into crevices, leading to mold, mildew, or rotting wood if the water penetrates insulation or flooring 1.

Best Practices for Power Washing Windows

Assess the Condition of Your Windows

Before starting, inspect your windows for any signs of damage. Look for:

  • Broken or Cracked Glass: Repair any broken or cracked glass before using a pressure washer 2.
  • Old or Missing Caulk: Replace any old or missing caulk to prevent leaks 2.
  • Damaged Seals: Check for condensation inside the window, which indicates damaged seals 2.

Proper Preparation

  • Dust and Clean: Start by dusting the sills and frames and use a mild cleaner for streak-free windows 2.
  • Remove Screens: For optimal cleaning and protection, remove the screens from the windows 2.

Adjust Pressure Washer Settings

  • PSI and Spray Width: Keep the PSI between 1,200 to 2,000 and adjust the nozzle to a wider spray setting to distribute the pressure evenly 2.
  • Test First: Test the pressure washer on a solid surface before using it on windows to ensure the pressure isn’t too strong 2.
  • Use Soap Solution: If dirt is caked on, use a soap solution to break it down before rinsing with water 2.
