Can polyethylene outdoor sofas be power-washed without damage?

Polyethylene outdoor sofas are known for their durability and resistance to harsh weather conditions, but can they withstand power-washing? The short answer is yes—most high-quality polyethylene furniture can handle power-washing if done correctly. However, using too much pressure or the wrong nozzle can cause damage over time.

To safely clean your polyethylene sofa, use a pressure washer with a wide-angle nozzle (40° or wider) and keep the pressure below 1,500 PSI. Avoid directing the stream at seams or weak points, as this may loosen adhesives or cause cracks. For routine maintenance, a mild soap solution and a soft brush are often sufficient.

Always check the manufacturer’s guidelines before power-washing, as some finishes or recycled polyethylene materials may require gentler care. Proper cleaning will extend the life of your outdoor sofa while keeping it looking fresh and vibrant.
