Pressure washing can be a quick way to clean urban outdoor furniture, but it requires careful consideration. While powerful for removing grime, the high-pressure stream can damage materials commonly found in urban settings. For metal furniture, pressure washing may strip protective coatings and accelerate rust formation. On wood pieces, it can splinter the surface and destroy finishes. Plastic and resin furniture might become etched or cracked from the forceful water impact.
Before pressure washing, always check manufacturer cleaning recommendations. Use the lowest pressure setting and maintain adequate distance from furniture surfaces. A wide-angle nozzle helps disperse pressure more gently. Avoid directing spray at joints, seams, or decorative elements where water can penetrate and cause structural damage.
For delicate urban furniture, consider alternatives like soft-bristle brushing with mild soap solution. Regular maintenance cleaning prevents buildup that requires aggressive methods. If using a pressure washer, test on an inconspicuous area first and keep the nozzle moving continuously. Proper drying after cleaning prevents moisture-related issues in humid urban environments.
Ultimately, while pressure washing can be appropriate for sturdy, all-weather furniture, gentler methods often preserve your urban outdoor pieces longer while maintaining their aesthetic appeal against city pollutants and weather exposure.
