Metal cleaning is the process of removing contaminants, such as dirt, grease, rust, and oxidation, from metal surfaces. This is essential for maintaining the integrity and appearance of metals used in various applications, including construction, manufacturing, and automotive industries. Common methods include mechanical cleaning, chemical cleaning, and electrochemical cleaning. Proper metal cleaning ensures better adhesion for coatings and paints, enhances corrosion resistance, and prolongs the lifespan of metal components. Techniques may involve using solvents, abrasives, or specialized cleaning agents, depending on the type of metal and the nature of the contaminants. Regular maintenance is crucial for optimal performance and safety.
