Chemical cleaning is a process that uses specific chemicals to remove contaminants, such as dirt, grease, and scale, from surfaces and equipment. This method is commonly employed in industries like manufacturing, oil and gas, and water treatment to maintain the efficiency and longevity of machinery and systems. The chemicals used in this process can vary widely, including acids, alkalis, and detergents, each designed for particular types of deposits. Proper safety measures and procedures are essential during chemical cleaning to protect workers and the environment from potential hazards associated with these substances.
