Metal fences are functional, resistant to precipitation and temperature fluctuations, and yet they still need some care.
Special “care” requires exquisite brass. Over time, as a result of oxidation, a green coating appears on the railing. For longer service, these traces are recommended to be removed using soft fabrics twice a year. It is better to use ready-made special cleanser for brass.
When caring for stainless steel, the main thing is not to disturb the oxide film deposited on the surface. Cleaning with chemically active substances and hard brushes will damage the layer and deprive the fence of anti-corrosion.
