How can I remove the sour milk smell from a carpet?
Answer: Not to worry, a nasty stain and smell like sour milk can be removed with BISSELL Enzyme products and deep cleaning.
The best option for removing the sour milk from your carpets is to apply an enzyme product such as Pet Stain & Odor Pre-treat for Carpet & Upholstery. Then you will want to deep clean the area with a portable deep cleaner and Little Green formula or an upright deep cleaner using 2X Professional Deep Cleaning formula. If do not have a deep cleaner, wipe up what you can and apply an enzyme product such as Pet Stain & Odor Pre-treat for Carpet & Upholstery. Place a damp towel over the stain for 48 hours. The enzymes will eat the sour milk that is deep into your carpet fibers. For a nasty spill like milk you may need to repeat this step depending on how deep and how much milk was spilt.
