We recommend using soap and warm water and focus on cleaning the interior of the milk pitcher after every shift. Milk contains fat, proteins, and sugars that can leave residue on surfaces, especially if only rinsed with water. Over time, this residue can harden and become more difficult to clean.
As milk spoils, lactose is fermented into lactic acid, increasing the acidity. Acids can slowly corrode metal, even stainless steel, though stainless steel is more resistant. Prolonged exposure to acidic substances can wear down the protective layer of stainless steel.
Using soap and warm water is standard for removing milk fats and proteins effectively. Soap helps break down the fat molecules that water alone cannot remove, preventing buildup.
After wash, we recommend you to dry it with towel and leave them right side up to air out. Drying is important because water left on the surface of stainless steel can cause water spots and possibly encourage corrosion in the long term. Proper drying extends the longevity of metal kitchenware.
