Cleaning a milk tank includes rinsing the tank with cold water and washing the tank with a warm liquid. During rinsing, the tank is finally rinsed with substantially warmer water than the cold water with which the tank is initially rinsed, the cold water being cold enough to remove milk residues such as proteins, from the milk tank. A dairy farm milk storage facility specifically adapted for carrying out this method is also described. Milk residues such as proteins are effectively rinsed away by the initially used cold water and no energy is consumed for heating this rinsing water. Subsequently the storage tank is gradually, evenly and very effectively pre-warmed by the final rinsing water prior to the washing stage, so less washing water is required to achieve the required washing temperature while thermal stresses occurring in the tank are kept low.
A method of cleaning the inside of a milk tank, including the stages of rinsing the tank with cold water of a temperature to cause removal of milk residues from the milk tank and subsequently washing the tank with a warm liquid that is substantially warmer than the cold water and contains at least one cleaning agent, including finally rinsing said tank during said rinsing stage with substantially warmer water than the cold water with which the tank is initially rinsed during said rinsing stage.
