Solutions of sulphuric acid find their main use as a preliminary step in descaling. Sulfuric acid provides a quick initial attack on scale deposits, and it is always followed by the much more controllable nitric/hydrofluoric treatment. Hydrochloric acid solutions behave similarly to sulphuric acid mixtures.
