Inhibited hydrochloric acid is generally used for removing rust from new boilers and insoluble deposit such as scale from old ones. Addition of reducing phosphoric acid to this acid results in high solubility of metal oxides or salts and anti-corrosive surface after cleaning, and can clean perfectly marine boilers economically even at room temperatures.Thiourea and fulfurol inhibits the corrosibility of this type of acid and addition of wetting agent lowers this rate of attack.Details of cleaning methods and results with inhibited reducing acid solution have been reported in this essay.
