Which nozzle on pressure washer is correct for decks?

For cleaning decks with a pressure washer, a 25-degree or 40-degree nozzle is typically recommended. The 25-degree nozzle provides a good balance between cleaning power and surface safety, while the 40-degree nozzle offers a gentler spray for more delicate surfaces. It's important to test in a small area first to avoid damage, especially with softer woods. Always maintain a safe distance from the surface while using the nozzle.
