Sodium Hydroxide (AKA Caustic Soda) is frequently used as an industrial cleaning agent where it is often called "Caustic". It is very dangerous to use but still the first choice for many wineries and breweries. Its ability to dissolve and remove a wide range of soils, oil, grease and stains makes it a good choice when other cleaners are not effective.
Safe to use on stainless steel but NOT on soft metals such as brass and aluminium.
