What are the effects of bird droppings on the surface of marble outdoor tree boxes?

Bird droppings can have several negative effects on the surface of marble outdoor tree boxes. Firstly, the acidic nature of bird poop can cause etching and erosion, dulling the marble's natural shine over time. Secondly, the droppings may lead to stubborn stains, especially if not cleaned promptly, as the pigments penetrate the porous marble. Additionally, prolonged exposure can weaken the marble's structural integrity, making it more prone to cracks and chips. To mitigate these effects, regular cleaning with pH-neutral cleaners and sealing the marble surface are recommended. Preventive measures, such as installing deterrents to keep birds away, can also help maintain the marble's appearance and longevity.
