Used as a strong alkaline cleaning agent in industrial and commercial settings, particularly in drain and oven cleaners due to its ability to dissolve grease and fats. Commonly employed in the production of soaps and detergents through saponification of fats and oils. Utilized in pH control for water treatment and various chemical manufacturing processes. Plays a key role in the preparation of potassium salts and in electroplating operations. Also used in food processing, such as in washing or peeling fruits and vegetables, and as a processing aid in cocoa and chocolate production. Found in some battery electrolytes, especially alkaline batteries, for its ionic conductivity.
