How Can You Clean A Vinyl Deck By Pressure Washing?

Vinyl decks are popular with homeowners who want low-maintenance, attractive outdoor flooring. Even the strongest vinyl decks are susceptible to accumulating dirt, mould, and mildew. These can affect their appearance over time and even cause long-term damage. When faced with this challenge, many homeowners wonder if they can clean a vinyl patio by pressure-washing.

This comprehensive guide explores pressure-washing vinyl decks. We examine its benefits, possible risks, and best practices for achieving a clean and well-maintained outdoor space.

Understanding Vinyl Decks:

Vinyl decks offer great protection against insects, moisture, and fading. They are also easier to maintain than wood because they don’t need staining. However, like any outdoor deck, vinyl surfaces are susceptible to dirt, algae, and other debris. Periodic cleaning is required to keep the decks looking good.

Potential Hazards and Considerations:

Pressure washing Lawrenceville can be a very effective method for cleaning vinyl decks. However, you should proceed with caution to avoid damaging any surface. Improper technique or excessive pressure may cause many problems.

  1. Vinyl Surface Damage: High-pressure water streams may etch or gouge vinyl surfaces, leaving unsightly marks or, in extreme cases, even structural damage.
  2. The Water Intrusion: Pressure-washing at close range or using excessive pressure can force the water beneath the vinyl deck board, leading to moisture-related problems such as mold and mildew.
  3. Color Fading: When pressure washing vinyl decks, using high water pressure and hot water can cause color fade.

Selecting the right pressure settings is crucial for reducing these risks. The manufacturer’s recommendation and the vinyl surface’s state should be considered when selecting the appropriate nozzles and pressure levels. Keeping a safe space from the deck surface and using gentle, sweeping strokes can also help to avoid damage.

Best Practice for Pressure Washing Vinyl Decks:

Use these tips before you start a vinyl deck pressure cleaning project to ensure safety and success.

  1. Inspecting the Deck: Before starting, inspect the Vinyl Deck for any signs or damage, including cracks, loose boards, and protruding nails. Make any necessary repairs before you begin pressure washing.
  2. Choose the Right Equipment: Make sure you choose a pressure washer with adjustable settings. It should also have a wide-angle nozzle to clean delicate surfaces like vinyl. Avoid using narrow nozzles or high-pressure settings that could cause damage.
  3. Prepare your Area: Remove furniture, obstacles, and plants from the deck. Cover nearby plants, outlets, and lights to protect them from overspray.
  4. Maintain the Proper Technique: Use sweeping gestures to spread the water, consistently holding a pressure washer nozzle (typically 12-18 inches away from the deck). Avoid staying in one area too much to avoid damage.
  5. Rinse Thoroughly. Once cleaning is complete, thoroughly wash the deck in clean water to remove all detergent residue and loose debris. Pay particular attention to areas where there may be water accumulation, such as between the deck boards.
