Wipe regularly with a soft cloth to wipe the surface dust. Try to use a mild cleaning agent and gently wipe. Do not put it together with other hard objects to avoid external impact and damage, and do not use hard materials to hit and strike, as this will cause the paint layer to warp and the chrome layer to fall off. Do not use a humidifier around the moisture-proof and sunscreen iron guardrail as much as possible, and avoid direct sunlight outside the window to prevent metal oxidation, deterioration, discoloration, and peeling of the surface paint. To prevent metal rusting, it is recommended to regularly wipe the surface with a cotton cloth dipped in a small amount of anti rust oil or sewing machine oil to keep it as bright as new. If the furniture has started to rust, oil can be applied to the rust area to remove the rust.
