What is fireplace rust?

Fireplace rust can occur on the metal components of a fireplace, including the grate, screen, and other hardware. Rust occurs when metal is exposed to moisture and oxygen over time, leading to the formation of iron oxide. In addition to being unsightly, rust can weaken metal and shorten the lifespan of the fireplace. Regular maintenance and cleaning can help prevent rust from forming. If rust is already present, it should be removed and treated with rust-inhibiting products to prevent further damage. In some cases, the affected parts may need to be replaced to ensure the safety and functionality of the fireplace.
