Is cast iron resistant to fountain chemical stains?
Cast iron is a popular material for outdoor fountains due to its durability and classic aesthetic. However, its resistance to fountain chemical stains depends on several factors. While cast iron is robust, it is prone to rust when exposed to water and chemicals over time.
Fountain chemicals, such as algaecides or chlorine, can accelerate corrosion if the iron isn’t properly treated. To enhance resistance, manufacturers often coat cast iron with protective layers like enamel or powder coatings. Regular maintenance, including sealing and cleaning, also helps prevent stains and rust.
For long-term use, consider stainless steel or coated cast iron fountains, which offer better chemical resistance. Ultimately, cast iron can withstand fountain chemicals with proper care, but untreated surfaces may degrade faster.
