Rust prevention involves methods to protect metal surfaces from corrosion caused by moisture and oxygen. Common techniques include applying protective coatings, such as paint or galvanization, which create a barrier between the metal and the environment. Regular maintenance, like cleaning and drying metal surfaces, also helps reduce rust formation. Another effective strategy is using rust inhibitors, which are chemicals that slow down the oxidation process. Additionally, storing metal items in dry, well-ventilated areas can minimize exposure to humidity. By implementing these practices, individuals can extend the lifespan of metal objects and structures, such as vehicles and tools.
