What are the effects of high-pressure washing on the surface integrity of WPC outdoor tree boxes?
High-pressure washing is a common method for cleaning outdoor surfaces, including wood-plastic composite (WPC) tree boxes. While it effectively removes dirt and debris, its impact on surface integrity varies. Excessive pressure can cause micro-cracks, fading, or surface roughening in WPC materials, potentially reducing longevity. However, moderate pressure with appropriate nozzles can clean without significant damage. To preserve WPC tree boxes, use low to medium pressure (below 1,500 psi) and maintain a safe distance. Regular inspections post-cleaning help identify early signs of wear, ensuring the durability of these eco-friendly outdoor solutions.
