Domestic dirt

Oh, the agony of spilled milk! Not only does it create a mess, but it also leaves behind an unpleasant odor if not dealt with promptly. Whether it’s a simple accident or the aftermath of a toddler’s tantrum, don’t fret. There are effective ways to deal with this household challenge, ensuring your carpet is spotless and odor-free once more. So, let’s dive in, shall we?

What You’ll Need:

  1. Mild dish soap
  2. Clean white cloth or paper towels
  3. Warm water
  4. Baking soda
  5. Cornstarch (or another type of starch)
  6. Vacuum cleaner
  7. Spray bottle
  8. A soft-bristled brush

Method 1: Using Soap

  1. Blot, Don’t Rub: Start by blotting up as much of the spilled milk as possible with a clean white cloth or paper towels. Remember, rubbing can push the milk deeper into the carpet fibers.
  2. Prepare a Soapy Solution: Mix a few drops of mild dish soap with warm water in a spray bottle. Shake well.
  3. Apply and Blot: Spray the soapy solution over the stained area. Allow it to sit for a few minutes, then blot with a clean cloth.
  4. Rinse: Dampen a cloth with clean warm water and blot the area to rinse out the soap. Ensure no residue remains, as it can attract dirt.
  5. Air Dry: Let the carpet air dry. If necessary, place a fan to speed up the drying process.

Method 2: Baking Soda and Starch

  1. Apply Baking Soda: Generously sprinkle baking soda over the stained and smelly area. This natural deodorizer will absorb the foul odor.
  2. Add Starch: Sprinkle a layer of cornstarch over the baking soda. Starch helps absorb moisture and helps remove odors.
  3. Wait: Let the mixture sit for several hours or overnight for maximum effectiveness.
  4. Vacuum: Using your vacuum cleaner, thoroughly vacuum up the baking soda and starch mixture.
  5. Brush: If needed, gently brush the carpet fibers with a soft-bristled brush to restore its appearance.

Coffee grounds are also great for removing sour milk odor from the carpet. You can apply it to the stain and leave it for a few hours, then remove it.
