To effectively remove the persistent mothball smell from a wool sweater, a multi-step approach combining airing, odor absorption, and gentle cleaning is recommended.
Mothballs contain chemicals like naphthalene or paradichlorobenzene, which sublime into a gas to deter moths. These chemicals leave a strong, lingering odor that can embed itself deeply into fabric fibers, especially natural ones like wool.
Effective Strategies for Odor Removal
Addressing the mothball smell requires patience and a methodical approach, focusing on neutralizing and absorbing the chemical residue.
1. Airing Out Your Sweater
The simplest initial step is to expose the sweater to fresh air, which helps dissipate the volatile compounds.
- Outdoor Exposure: Hang the wool sweater outdoors on a clothesline on a dry, breezy day. Choose a shaded or partially shaded area to avoid direct, intense sunlight which can fade or damage wool fibers.
- Good Ventilation: Ensure there's good air circulation around the sweater. Avoid damp conditions, as moisture can trap odors or encourage mildew.
- Duration: This process can take several days to a few weeks, depending on the strength of the odor and the weather conditions. Bring the sweater indoors at night or during inclement weather.
2. The Power of Baking Soda Soak
Baking soda is a renowned natural deodorizer that effectively neutralizes the acidic properties of mothball chemicals, making their odor less potent.
- Prepare the Solution: Fill a clean basin or bathtub with cool water. Add a generous amount of baking soda – approximately 1/2 to 1 cup for a single sweater – ensuring it dissolves thoroughly in the water.
- Submerge and Soak: Gently submerge your wool sweater into the baking soda solution, making sure it is fully saturated.
- Soaking Duration: Allow the sweater to soak for 24 hours. This extended period is crucial for the baking soda to properly neutralize the chemical properties of the mothballs.
- Thorough Rinse: After soaking, rinse the sweater thoroughly under cool, running water until all baking soda residue is gone and the water runs clear.
- Gentle Squeeze: Carefully squeeze out excess water without twisting or wringing the wool, which can stretch or damage the fibers.
3. Other Odor Absorbers
Beyond soaking, various natural materials can further draw out and trap lingering smells.
- Activated Charcoal: Place the sweater in a large, airtight plastic bag or container with several pieces of activated charcoal. Seal it and leave for several days. Activated charcoal is highly porous and excellent at absorbing odors.

- Coffee Grounds: Fresh, dry coffee grounds can also absorb odors. Place them in an open container near or inside an enclosed space with the sweater. Ensure the coffee grounds do not directly touch the wool to prevent staining.
- Cedar Blocks/Chips: Cedar is a natural moth repellent and has a pleasant aroma that can help mask and absorb other smells. Place cedar products in the storage area with the sweater (once clean) to prevent future issues.
4. Vinegar Solution
White vinegar, a mild acid, can help break down and neutralize odors, making it another effective tool.
- Spray Method: Mix equal parts white vinegar and cool water in a spray bottle. Lightly mist the sweater and allow it to air dry. Always test on an inconspicuous area first to ensure no discoloration.
- Soak Method: For more stubborn odors, you can add 1 cup of white vinegar to a basin of cool water and soak the sweater for about an hour before rinsing thoroughly and laying flat to dry.
5. Gentle Hand Washing
If the odor persists after the above treatments, a gentle hand wash specifically designed for wool may be necessary. Wool is delicate and requires careful handling to prevent shrinkage or damage.
- Wool-Specific Detergent: Use a mild, pH-neutral detergent formulated for wool or delicate garments.

- Cool Water: Fill a clean basin with cool water.
- Submerge and Swish: Submerge the sweater and gently swish it around. Avoid rubbing, scrubbing, or twisting.
- Rinse Thoroughly: Rinse the sweater under cool, running water until all soap residue is completely removed.
- Remove Excess Water: Gently press the water out of the sweater using a clean, dry towel. Do not wring.
- Lay Flat to Dry: Reshape the sweater to its original dimensions and lay it flat on a clean, dry towel or a mesh drying rack. Keep it away from direct heat or sunlight.
6. Professional Cleaning
For extremely strong odors, highly delicate or expensive wool sweaters, or if you are hesitant to try home remedies, consider taking the garment to a reputable professional dry cleaner. Inform them about the mothball odor so they can use appropriate treatment methods.
Tips for Preventing Future Odors
Prevention is crucial for maintaining the freshness of your wool garments and avoiding the need for mothballs.
- Store Clean: Always ensure wool sweaters are completely clean and dry before storing them.
- Breathable Storage: Use breathable garment bags made of cotton or mesh, or acid-free storage boxes. Avoid plastic bags, which can trap moisture and odors.
- Natural Repellents: Opt for natural moth deterrents like cedar blocks, lavender sachets, or cedar balls. Replace or refresh these regularly.
- Regular Airing: Even when stored, periodically air out your wool items to keep them fresh.
