How do stone outdoor trash cans interact with de-icing salts used on nearby pavements?

Stone outdoor trash cans, often made from materials like granite or concrete, can interact with de-icing salts used on nearby pavements in ways that affect their longevity and appearance. De-icing salts, such as sodium chloride or calcium chloride, are applied to melt ice and snow on walkways and roads. When these salts come into contact with stone surfaces, they can lead to chemical reactions. For instance, salts may penetrate the porous structure of the stone, causing internal crystallization during freeze-thaw cycles. This process can result in cracking, spalling, or surface erosion over time. Additionally, salts can accelerate the deterioration of any metal components, like hinges or lids, through corrosion. To mitigate these effects, it's advisable to choose dense, low-porosity stones, apply sealants regularly, and ensure proper drainage to minimize salt accumulation. Regular cleaning with water can also help remove residual salts and preserve the trash can's integrity in winter conditions.
