What are the effects of using pressure washers on powder-coated metal outdoor chairs?
Using pressure washers on powder-coated metal outdoor chairs can be both effective and risky. On one hand, high-pressure water efficiently removes dirt, grime, and mildew, restoring the chair's appearance. However, excessive pressure or close-range spraying may damage the powder coating, leading to chipping, peeling, or reduced longevity. To minimize risks, use a low-pressure setting (under 1,500 PSI) and maintain a safe distance (at least 12 inches). Avoid harsh nozzles and direct angles. Regular gentle cleaning preserves the coating's integrity while keeping chairs looking new. Always test a small area first to ensure compatibility.
