3. Chemical and mechanical

4. Manual and automated

The correct answer is: Chemical and mechanical

The two types of cleaning methods that are most commonly recognized in various industries, including millwrighting, are chemical and mechanical cleaning. Chemical cleaning involves the use of chemical agents to dissolve, lift, or remove contaminants from surfaces. This method is particularly effective for breaking down grease, oil, and other substances that mechanical means may struggle to eliminate effectively. Chemicals can penetrate hard-to-reach areas and are often used when precision cleaning is required to meet certain industry standards. Mechanical cleaning, on the other hand, relies on physical techniques to scrub or dislodge dirt and debris from surfaces. This includes the use of tools such as brushes, scrapers, and high-pressure water jets. Mechanical cleaning is an important method for removing larger particles or when a chemical method cannot be safely applied. Together, these methods provide a comprehensive approach to cleaning in industrial settings, where maintaining equipment and ensuring that surfaces are contaminant-free is crucial for operational efficiency and safety.
