Corrosionpedia explains Ammonium Fluoride
Ammonium fluoride is commonly used in several applications. Because it is water soluble, it can be bought and used as a solid or as an aqueous solution. One popular use is for etching glass. In the right amounts and with the right exposure times, ammonium fluoride can be used to polish certain types of metals as well. Cleaning and disinfecting can be performed by using ammonium fluoride. Some industrial chemical processes rely on ammonium fluoride for chemical reactions. Wood preservation is another application.
Ammonium fluoride can be harmful to humans and the environment. Death can result if the exposure is acute or long-term. Ammonium fluoride has the potential to burn the skin and should never be ingested. It can be even more dangerous if it comes into contact with water because it can produce hydrofluoric acid. Excessive respiration of ammonium fluoride can irritate the throat and lungs, making it difficult to breathe easily.
