Can pressure washing damage polypropylene outdoor bar stool surfaces?
Pressure washing can potentially damage polypropylene outdoor bar stool surfaces if not done carefully. Polypropylene is a durable plastic, but high-pressure water jets may cause surface scratches, fading, or even structural weakening over time. For safe cleaning, use a low-pressure setting (below 1,200 PSI) and hold the nozzle at least 12 inches away from the surface. Mild soap and a soft brush are often safer alternatives for regular maintenance. Always test a small, inconspicuous area first and avoid using hot water, which can warp the material. Proper care will help maintain your bar stools' appearance and longevity.
