How do polyethylene’s hydrophobic properties influence water-themed sculpture maintenance?

Polyethylene's hydrophobic nature, which repels water, plays a significant role in the maintenance of water-themed sculptures. While this property prevents water absorption and reduces risks like cracking or microbial growth, it also presents unique challenges. Dirt and mineral deposits from water exposure can accumulate on the surface without being washed away naturally, requiring specialized cleaning methods. Traditional water-based cleaners may bead up and fail to penetrate, necessitating the use of mild detergents or alcohol-based solutions. Additionally, the material's resistance to moisture makes it durable for outdoor installations but may lead to uneven weathering if not regularly maintained. Understanding these effects helps conservators adopt proactive care strategies to preserve the sculpture's aesthetic and structural integrity.
