The following is an explanation of these products: Metal rust removal spray: Metal rust removal spray is a product designed to address oxidation and corrosion issues on metal surfaces. It contains chemical solvents and corrosion inhibitors, which can quickly dissolve and remove rust on metal surfaces, and provide certain rust prevention protection. Metal rust prevention oil: Metal rust prevention oil is designed to protect metal surfaces from oxidation and rust. It is usually a lubricating grease containing preservatives and antioxidant additives, which can form a protective film on the metal surface to prevent oxidation and rust. Lubricating oil: Lubricating oil forms a lubricating film between metals, reducing friction and wear. Lubricating oil is usually used for mechanical equipment, engines, and other metal components that require lubrication. Different types of lubricants are suitable for different applications and working conditions. Cleaning agent: Metal surfaces often accumulate dirt and grease, requiring the use of cleaning agents for cleaning. Metal cleaning agents can remove dirt, grease, and other impurities, restoring the smoothness and brightness of metal surfaces.
