Explanation

Beyond its important natural role in human digestion, hydrochloric acid also has significant industrial applications, including its use in various metal cleaning and processing procedures, such as removing rust and scale from steel surfaces before further manufacturing, a process known as pickling in an industrial rather than culinary sense. It is also used in various other chemical manufacturing processes across a range of industries. Industrial-grade hydrochloric acid is typically far more concentrated and must be handled with considerably more caution than the naturally occurring acid found within the stomach.
