Can You Jet Wash Composite Decking?

Jet Washing vs. Power Washing:

Jet washing and power washing are terms often used interchangeably, but they can have different meanings depending on the region or context. In general, both involve using high-pressure water to clean surfaces, but the key difference lies in the water pressure. Jet washing typically refers to using a pressure washer with a higher psi (pounds per square inch) setting, while power washing involves a medium psi setting. For the purpose of cleaning composite decking, either term may be used, but it's important to choose an appropriate pressure level to avoid damage.

Considerations for Using a Jet Washer:

Check Manufacturer Guidelines: Before using a jet washer on composite decking, refer to the manufacturer's guidelines for cleaning and maintenance. Some decking brands may have specific recommendations to protect the material.

Choose the Right Pressure Setting: Adjust the pressure washer to a suitable psi for cleaning composite decking. High-pressure settings can potentially damage the surface or push water between boards, leading to issues like mold or mildew.

Use the Correct Nozzle: Select a wide-angle or fan nozzle rather than a narrow, concentrated one. This helps distribute the water pressure more evenly, reducing the risk of damage.

Maintain a Safe Distance: Keep the jet washer nozzle at a safe distance from the decking surface. Too close can cause damage, while too far may reduce cleaning effectiveness.

Test in an Inconspicuous Area: Before starting on the entire deck, test the jet washer in a small, inconspicuous area to ensure it doesn't cause any harm. This allows you to fine-tune the pressure settings if needed.

Best Practices for Jet Washing Composite Decking:

Sweep or Rinse First: Remove loose debris, dirt, and leaves from the deck surface using a broom or hose before jet washing.

Work in Sections: Divide the deck into manageable sections to ensure thorough cleaning. This also helps in controlling the cleaning process and avoiding uneven results.

Follow a Pattern: Move the jet washer in a consistent pattern to prevent streaks or uneven cleaning. Avoid lingering in one spot for too long.

Regular Maintenance: Periodic jet washing is effective for removing built-up grime, but regular sweeping and occasional gentle cleaning can help prevent the need for high-pressure washing too frequently.

Protect Surroundings: Cover nearby plants and furniture to prevent any potential damage from water spray or cleaning agents.
