Pressure washing can be an effective way to clean outdoor furniture, but it requires careful consideration. While powerful for removing dirt and grime from metal and hard plastic pieces, high-pressure water can damage softer materials like wood and wicker. The key factors include your furniture material, pressure washer settings, and proper technique.
For metal and durable plastic furniture, pressure washing with a wide-angle nozzle and maintaining a safe distance works well. However, for wooden furniture, use low pressure settings or avoid pressure washing altogether to prevent surface damage and water penetration. Wicker and rattan furniture should never be pressure washed as the force can break delicate fibers.
Always test on an inconspicuous area first and use the lowest effective pressure. Keep the nozzle at least 12 inches from the surface and maintain consistent movement to prevent concentrated damage. Consider gentler alternatives like soft brushes with mild soap for delicate materials. Regular maintenance with appropriate cleaning methods will extend your outdoor furniture's lifespan while keeping it looking its best.
