Are granite outdoor trash cans more resistant to fading from air pollution?

Granite outdoor trash cans are known for their exceptional durability and resistance to environmental factors, including fading from air pollution. Granite is a natural stone composed of tightly interlocking mineral crystals, primarily quartz and feldspar, which form a non-porous, dense surface when properly sealed. This inherent density makes it highly resistant to the chemical agents found in air pollution, such as acidic rain, industrial emissions, and vehicle exhaust, which typically cause fading, discoloration, or surface degradation in less robust materials. Unlike synthetic materials or metals that may oxidize or break down over time, granite's mineral composition ensures that its color is integral throughout the stone, not just a surface coating. Therefore, it does not "fade" in the traditional sense. While prolonged exposure to heavy pollutants might lead to a slight dulling of the surface sheen, the core color of the granite remains stable. Regular cleaning and periodic sealing are recommended to maintain its luster and protective barrier, but overall, granite stands as a superior, fade-resistant choice for outdoor trash cans in polluted urban areas, outperforming many alternative materials in long-term color retention and structural integrity.
