Phosphoric acid is used as an intermediate in the production of animal feed supplements, water treatment chemicals, metal surface treatments, etching agent, and personal care products such as toothpaste. It is used as a catalyst in the petroleum and polymer industry. Phosphoric acid is used in food as a preservative, an acidulant, and flavor enhancer it acidifies carbonated drinks such as Coca Cola and Pepsi, giving them a tangy flavor. Phosphoric acid is used as a rust remover and metal cleaner. Naval Jelly is approximately 25% phosphoric acid. Other uses for phosphoric acid include opacity control in glass production, textile dyeing, rubber latex coagulation, and dental cements. 

Gluconates and glucoheptonates are essential components of many alkaline rust removers and cleaners, paint strippers, and etchants. They frequently cause complexation of dissolved heavy metals such as copper, nickel, and zinc. Conventional sodium hydroxide treatment does not result in sufficient precipitation of these complexed metals to meet EPA standards. In tests performed by Srinivasan (1983), the use of lime or calcium hydroxide proved far better. In particular, lime treatment resulted in more metal removal, better flocculation and faster sludge settling, and could also be used in conjunction with sodium hydroxide treatment.
