How does prolonged exposure to acidic cleaners affect polyethylene outdoor trash cans?

Prolonged exposure to acidic cleaners significantly compromises the structural integrity of polyethylene outdoor trash cans. While high-density polyethylene (HDPE) possesses inherent chemical resistance, concentrated acidic substances gradually break down polymer chains through chemical degradation. This process initially manifests as surface etching and loss of plasticizer, leading to increased brittleness. Over time, micro-cracks develop and propagate, particularly in stress-concentrated areas like handles and corners. The degradation accelerates under UV exposure, as sunlight weakens the molecular structure before acid contact. Ultimately, affected trash cans become prone to cracking, fading, and premature failure. For maintenance, use pH-neutral cleaners specifically formulated for polyethylene products to ensure longevity and performance.
