Here at BISSELL, we enjoy eggnog during the holidays as well! Luckily, a smelly stain like sour milk can be removed with BISSELL Enzyme products and carpet cleaning.
The best option for removing the sour milk from your carpets is to apply an enzyme product such as Professional Stain & Odor Remover. Why a Pet Stain & Odor product you ask? Because it contains the enzymes that will eat the sour milk that is carpet into your carpet fibers. After treating the area place a damp towel over the stain for 48 hours. You may need to repeat this step depending on how carpet and how much milk was spilled.
For best results you will want consider carpet cleaning the area with a portable or upright carpet cleaner.
