The instrument cleaning process according to the present invention comprising a boiling step of boiling instruments with deposits thereon in a boiling vessel, allowing water to soak into the deposits, a drying step of drying the boiled instruments with hot air in a drying vessel to dry the water-soaked deposits, and a washing step of washing the dried instruments in a washing vessel to remove the dried deposits. Thus, the instruments with deposits thereon are boiled in the boiling step, in which water soaks into the deposits, then the boiled instruments are dried in the drying step, whereby the water soaked into the deposits is evaporated to weaker the adhesive force of the deposits, and subsequently the dried instruments are washed in the washing step, whereby the deposits which have been made less adhesive are removed from the instruments.
