The fastest way to get milk out of car carpet is to act immediately. Fresh milk is much easier to clean than dried, sour milk. Your primary goal is to absorb as much liquid as possible, then use a cleaning solution to break down the fats and proteins before the smell sets in.
Start by blotting, not rubbing, the spill with a stack of paper towels or a clean, absorbent microfiber cloth. Rubbing will grind the milk deeper into the carpet fibers. Once you've absorbed the bulk of the liquid, create a simple cleaning solution. A mixture of dish soap, which is designed to cut through grease, and warm water is highly effective. Alternatively, a solution of white vinegar and water can help neutralize the sour odor.
Apply a small amount of your chosen solution to the area and continue to blot. You may need to repeat this process several times. After cleaning, rinse the area by blotting with a cloth dampened with plain water to remove any soap residue, which can attract more dirt. Finally, press dry with fresh towels and allow the carpet to air dry completely with the car windows down or a fan running. Leaving the carpet damp can lead to mold and mildew.
For severe or old spills, a dedicated upholstery cleaner or a wet/dry vacuum is the most effective tool. The key is speed and thorough drying.
