Since sour milk has such a strong and pungent odour, this smell will not just go away on its own as time passes.
Baking soda
Since it is likely that the bacteria have started to spread, it is prudent to venture far beyond the spill location. Using a soft-bristled brush or a cloth, work the baking soda into the fiber. To allow it to do its magic, leave it out at least one night; ideally, three or four days.
White Vinegar: White vinegar is another affordable option. Mix one part vinegar with four parts water in a spray bottle. Saturate the affected area and let it sit for about five hours before blotting it dry.
Sour milk has an unpleasant smell, but baking soda is a convenient odor-absorbing tool to always have on hand. Generously sprinkle baking soda onto the affected area, whether it is wet or dry, and leave it overnight. In the morning, vacuum the area thoroughly.
Smell: If milk has a bad smell, it may indicate spoilage. Fresh milk should have a mild, pleasant aroma. A sour or off smell usually means that bacteria have started to grow, and it's best not to consume it.
Stewart says that although most commercially purchased milk is pasteurized to prevent bacterial growth, improper storage can result in quicker spoilage. "Warmer temperatures promote bacterial growth, causing the milk to go bad," she says.
In most cases, symptoms caused by drinking spoiled milk resolve within 12-24 hours. The key is to prevent dehydration by sipping small amounts of fluid that contain sugar or electrolytes, such as popsicles and oral rehydration fluids (Pedialyte® for children).
Clean the Refrigerator and Freezer
If you really want to remove that smell, skip them—nothing works as well as a thorough clean. To start, spray interior surfaces with either a mixture of water and vinegar or a plant-based all-purpose cleaner and wipe everything down with a warm, damp microfiber towel, says Ruozzi.
The method for removing the fermentation odor may include supplying 0.5 to 10 times the amount of the culture medium per hour to the above-described lactic acid bacteria culture solution at 35 to 95 ° C.

Besides a thyroid disorder, other contributing factors to sour-smelling sweat include: Diet and Hydration: Your diet and hydration levels can affect your body odor. Consuming certain foods like garlic, onions, spicy foods, and processed foods can release volatile compounds through sweat, causing unpleasant smells.
Baking soda has been used for decades to eliminate odours. It's inexpensive, so use it liberally! Sprinkle baking soda directly on the carpet or upholstery where the milk spill occurred. Feel free to go well beyond its original borders; the bacteria may have begun to spread.
Smell does not usually contain bacteria, which carry disease and are much larger than the gaseous molecules that make up a smell. So the odor itself cannot make you sick.
Leave a cup of coffee grinds in your car overnight, and it will absorb any unpleasant odors. Your vehicle will smell like a coffee shop instead of a garbage truck.
Remove paper and clean with vinegar and water. Sprinkle fresh coffee grounds or baking soda loosely in a large, shallow container in the bottom of the refrigerator and freezer. Place a cotton swab soaked with vanilla inside the refrigerator and freezer. Close door for 24 hours.
Expiration dates are poor indicators of whether milk is safe to consume. The smell and appearance of the milk are clearer signs of how safe the milk is for consumption. Spoiled milk will produce a sour smell as the bacteria produce lactic acid. The smell will intensify after the milk becomes unsafe for consumption.
Both lactococci and lactobacilli begin to multiply exceptionally rapidly in the danger zone, accelerating the natural spoilage process that occurs in dairy. The byproduct of this conversion process is a very pungent smell that we all associate with spoiled milk.
Don't worry if the milk in your refrigerator is lightly soured. It's quick and easy to make homemade cottage cheese with it.
Like soured milk, spoiled milk also eventually separates, but in this case, this has happened because of spoilage bacteria instead of good bacteria. The result will smell bad, taste bad, and will possibly give you a sour stomach if you consume too much of it.
If you're unsure whether or not your kefir has expired, here are some telltale signs. Kefir has a fresh, tangy scent similar to a cup of yogurt. However, if you smell something rotten, acrid, and sour, it's time to replace your kefir.
The Bottom Line. If you aren't lactose-intolerant or allergic to dairy, it's totally OK to enjoy a regular glass of milk each day. From improving bone health to helping mitigate cognitive decline, drinking milk and incorporating other dairy items into your diet can come with some health benefits.
Lactic acid in the composition of fermented milk products stimulates the functions of various digestive glands, so it fosters the digestion process. The regular consumption of sour milk also improves the function of the intestines, helping to avoid constipation.
The general rule of thumb is to discard any perishables that have been stored above the “Danger Zone” of 40° F for more than two hours, no matter what their appearance or odor (and never taste the food to try and determine whether it's still safe).”
