How to power wash a deck effectively and safely?

To power wash a deck effectively and safely, start by clearing the deck of any furniture or debris. Use a low-pressure setting on the power washer to avoid damaging the wood. Hold the nozzle at a consistent distance from the deck surface and work in a sweeping motion. Always wear protective gear, such as goggles and gloves, and follow the manufacturer's instructions for the power washer. After washing, allow the deck to dry completely before applying any sealant or stain.
