The first step in the corrosion removal process is to clean and strip the area. This initial step is crucial because it involves removing any surface contaminants such as dirt, oil, grease, or existing corrosion products that could hinder further processing. Proper cleaning ensures that the underlying metal is exposed and can be adequately inspected, which is vital for evaluating the extent of corrosion and deciding on the appropriate removal and treatment processes.

By beginning with a thorough cleaning, subsequent actions, such as neutralization and restoration of protective coatings, can be carried out more effectively. Additionally, if the metal surface is not clean, any attempts to assess or treat corrosion could be compromised, leading to incomplete removal and potential for recurrence. Therefore, effective surface preparation sets the foundation for all other steps in the corrosion management process.
