How it's used
Refers specifically to high concentration acetic acid used for industrial or heavy duty cleaning purposes rather than culinary seasoning. While it shares the character for vinegar, it is caustic and should never be consumed directly. It is frequently employed as a natural, potent descaling agent for household appliances.
