The duration for a sour milk smell to dissipate depends largely on the surface it has been spilled on and the ventilation of the area. Typically, with proper cleaning and good air circulation, the smell should begin to fade within 24 to 48 hours. To expedite the process, cleaning the affected area with a mixture of baking soda and water or using white vinegar can neutralize the odor more quickly. Ensuring the area remains well-ventilated and possibly using air fresheners can also help mask the odor in the meantime.
