If you're looking to freshen up smelly laundry without using a washing machine or dryer sheet, here are a few alternative methods you can try:
Vinegar: White vinegar is a natural deodorizer and can help eliminate odors from clothes. Dilute a cup of white vinegar in a basin or sink filled with water, then soak the smelly clothes for 30 minutes to an hour. Afterward, rinse the clothes thoroughly and hang them to dry.
Baking soda: Baking soda is known for its odor-absorbing properties. Dissolve half a cup of baking soda in a basin of warm water and soak the smelly garments for 30 minutes. Rinse well and allow the clothes to air dry.
Lemon juice: Lemon juice has a refreshing scent that can help combat odors. Squeeze the juice of one or two lemons into a basin of water and soak the clothes for 30 minutes. Rinse thoroughly and hang them to dry in the sunlight, as sunlight can also help eliminate odors.
Essential oils: Essential oils can provide a pleasant fragrance to freshen up your laundry. Add a few drops of your favorite essential oil, such as lavender or citrus, to a spray bottle filled with water. Lightly mist the clothes and let them air dry.
Fresh air and sunlight: Hanging your clothes outside in the fresh air and sunlight can work wonders in removing odors. The sunlight's ultraviolet rays help kill bacteria and freshen fabrics naturally. Ensure your clothes are hung in a well-ventilated area and protected from direct sunlight, as excessive sunlight exposure can fade colors.
Remember, these methods can help freshen up mild odors, but they may not be sufficient for deeply embedded or persistent smells. If the odor persists, it's advisable to launder the clothes properly using a washing machine or seek professional cleaning if necessary.
