Can synthetic rattan outdoor sofas be power-washed without damaging the material?

Synthetic rattan outdoor sofas are a popular choice for patios and gardens due to their durability and weather-resistant properties. However, many owners wonder if they can use a power washer to clean them without causing damage.

The short answer is yes—but with caution. Synthetic rattan is designed to withstand outdoor conditions, including moisture, but excessive pressure from a power washer can loosen the weave or damage the resin coating over time. For safe cleaning, follow these tips:

1. Use Low Pressure: Set the power washer to a gentle setting (under 1,500 PSI) and hold the nozzle at least 12 inches away from the surface.

2. Avoid Direct Angles: Spray at a 45-degree angle to prevent water from forcing its way into the material.

3. Mild Soap Solution: Mix a mild detergent with water for stubborn stains instead of relying solely on high pressure.

4. Air Dry Naturally: Let the sofa dry in the sun to prevent mold or mildew buildup.

For routine maintenance, a soft brush and hose rinse are often sufficient. Power-washing should be reserved for deep cleaning every few months. By following these guidelines, your synthetic rattan sofa will stay looking fresh without compromising its longevity.
