How to Get Mildew Smell from Carpet – Method # 1

  1. As soon as you discover the smell, begin to vacuum the affected area as soon as possible. If possible, use a large, more powerful vacuum instead of a small hand vacuum. This will help remove even more dust and dirt from the affected area.
  2. Mix 1 cup of vinegar with 2 cups of warm water. Be sure to not add too much vinegar, as you don’t want to create too strong of a vinegar smell in your home by over wetting the carpet.
  3. Pour this vinegar and warm water solution into a spray bottle before applying to the carpet. This will ensure you don’t soak the carpet fibers, as this could cause new mildew deposits to form.
  4. Next, pour a generous amount of baking soda directly onto the affected area of your carpet.
  5. Give the carpet some time to dry before vacuuming the baking soda completely.
