- High-impact DIY mistake — Insufficient Safety Precautions: Always wear protective gear and ensure the area is clear of obstructions and bystanders.
- When hiring a professional, provide them with the size and material of the deck, as well as any specific cleaning or staining requirements. Ask about their experience with pressure washing and their process for protecting surrounding surfaces.
- Request a detailed quote that includes the cost of materials, labor, and any additional services such as sealing or staining. Be wary of low-ball estimates that may indicate a lack of experience or attention to detail.

DIY steps
- Before starting, ensure the area is clear of furniture, plants, and other obstructions. Wear safety goggles and keep children and pets away. Check the pressure washer's manual for specific instructions on usage and safety precautions.
- Mix the deck cleaner concentrate with water according to the manufacturer's instructions. Apply the solution to the deck using a scrub brush, working in sections to maintain even coverage. Allow the solution to sit for 10-15 minutes to penetrate the wood.
- Rinse the deck thoroughly with the pressure washer, starting from the top and working down to prevent dirt and debris from running back onto clean areas. Use a wide fan tip and keep the nozzle at least 12 inches away from the surface.
- For tougher stains or mildew, apply a bleach alternative and let it sit for 10-15 minutes before rinsing. Be cautious not to over-saturate the wood, as this can cause damage or warping.
- Use a clean water rinse to remove any remaining dirt, debris, or cleaning solution. Check the deck for any remaining stains or areas that may need additional attention.
- Allow the deck to air dry completely before applying any sealants or finishes. Remove any safety goggles and clean up any equipment and materials.
