Maintenance of Corten Fire Spheres
Regular Debris Removal: After each use and once cooled, remove ash and debris to prevent clogging and promote air flow for better fires.
Surface cleaning: Regularly wipe the surface of the fire spheres with a clean damp cloth to remove dust, stains, etc. For stubborn stains, a mild cleaning agent can be used to gently wipe them, but it is important to avoid using cleaning agents containing acidic or corrosive components to avoid damaging the rust layer on the surface of the corten steel and affecting its protective performance.
Rust proof
Natural rust layer maintenance
The rust layer on the surface of Corten steel is its natural protective barrier, and it should be avoided as much as possible in daily use to damage this rust layer. Do not scratch the surface of the fire spheres with sharp objects to prevent damage to the rust layer, which may expose the internal metal and cause corrosion. If the rust layer is found to have partial detachment or damage, It can be naturally oxidized for repair. Generally, in a natural environment, the rust layer will gradually regrow and cover the damaged area.
Special case handling
In some harsh environments (such as high humidity and high salt areas), the corten steel fire spheres may experience accelerated rusting. At this point, it is possible to consider using specialized anti rust paint to protect the fire spheres. Before applying anti rust paint, it is necessary to clean the surface of the fire spheres to ensure that there are no impurities such as dust and oil stains. Then, apply the anti rust paint evenly according to the product instructions to enhance the anti rust ability of the fire spheres and extend its service life.
