Complete Guide: Safe and Effective Deck Pressure Washing

deck pressure washingPressure washing is an excellent tool for deep cleaning your deck, but using it properly is essential to avoid damaging the natural wood surface. Following these precautions help keep deck pressure washing safe for your surroundings.

Guide to pressure washing your deck 

Step 1: Safety First

Before starting, prioritize safety to prevent injuries and damage. Follow these precautions:

  1. Protective Gear: Wear protective clothing that covers your skin and safety goggles to shield your eyes.
  2. Clear the Area: Keep family members and pets at a safe distance while you work, as the high-pressure spray can be dangerous.
  3. Practice Spraying: Familiarize yourself with the pressure washer’s spray by practicing without aiming at anything.
  4. Cover Plants and Objects: Use a plastic drop cloth to protect shrubs, gardens, air conditioning units, and electrical outlets.

Step 2: Pressure Washing vs. Power Washing

Be sure to use a pressure washer, not a power washer, for your deck. Pressure washers utilize cold tap water, which is gentler on natural wood decking, while power washers produce highly pressurized steam and can damage the wood.

Step 3: Precautions for Composite Decking

Avoid pressure washing composite decking as it is softer than natural wood and can be easily damaged. Instead, use a garden hose, scrub brush, and gentle soap for cleaning.

Step 4: Set Up and Test the Pressure Washer

Connect your pressure washer to the hose and start at the lowest power setting. Test the water pressure on an inconspicuous area of the deck to find the lowest effective setting that removes dirt without harming the wood.

Step 5: Apply Deck Cleaning Solution (Optional)

Step 6: Pressure Wash the Deck

Start by washing the deck railings and then move on to the boards. Work from your house outward, following the wood grain with wide, horizontal sweeps. Overlap each area slightly to avoid visible cleaning edges.

Control the pressure and aim by sweeping your arm laterally and maintaining a six-inch distance from the nozzle tip to the boards.

Step 7: Repeat as Needed

If necessary, apply additional cleaning solution or make multiple passes with the pressure washer to achieve the desired results.

Step 8: Allow the Deck to Dry

After Myrtle Beach pressure washing, let your deck dry for at least two full days to prevent bending or warping of the wood.

Step 9: Spot Sanding (If Required)

If you notice any splinters or rough areas after drying, spot-sand those sections using rough sandpaper.
