How To Get Smell Out of Underwear: Step-by-Step

Persistent odors in underwear can be a nuisance, affecting your comfort and confidence throughout the day. If you've ever wondered how to get the smell out of underwear effectively, you're not alone. This comprehensive guide will walk you through proven methods to eliminate those stubborn odors, from pre-treatment techniques to the best washing practices. Discover the secrets to maintaining fresh and odor-free underwear, no matter your lifestyle or activity level.

Why Does My Underwear Smell?

Underwear can develop unpleasant odors due to a variety of factors, including sweat, bacteria, and bodily fluids that accumulate throughout the day. These elements create a breeding ground for bacteria, which thrive in warm, moist environments and produce foul-smelling compounds. Additionally, certain fabrics can trap odors more easily than others, and improper washing techniques may fail to fully eliminate these smells. Lifestyle factors such as diet, hygiene habits, and physical activity levels can also contribute to persistent odors. Understanding these causes is the first step in effectively addressing and preventing unpleasant smells in your underwear.


Do Some Underwear Fabrics Retain Smell More Than Others?

Yes, some underwear fabrics are more prone to retaining odors than others. Synthetic materials like polyester, nylon, and spandex tend to trap sweat and bacteria, leading to persistent smells. These fabrics are less breathable and can create a moist environment that encourages bacterial growth. On the other hand, natural fibers such as bamboo are more breathable and absorbent, allowing for better air circulation and moisture wicking, which helps reduce odor retention. Understanding the properties of different fabrics can help you make informed choices to keep your underwear smelling fresh.

How To Get Smell Out of Underwear

Step 1: Pre-Treatment

  1. Rinse Immediately: Rinse your underwear with cold water as soon as possible to remove sweat and bodily fluids.
  2. Soak in Vinegar Solution: Soak the underwear in a mixture of one part white vinegar to four parts water for 30 minutes to neutralize odors.
  3. Apply Baking Soda Paste: Create a paste with baking soda and water, and apply it to the smelly areas. Let it sit for 15-20 minutes before washing.

Step 2: Effective Washing Methods

  1. Use a Specialized Detergent: Choose a detergent designed for eliminating odors, such as those containing enzymes or activated charcoal.
  2. Wash in Hot Water: Wash the underwear in the hottest water safe for the fabric to kill bacteria and remove odors.
  3. Add Odor Removers: Add a cup of white vinegar or a specialized laundry booster to the wash cycle for extra odor-fighting power.

Step 3: Proper Drying Practices

  1. Air Dry in Sunlight: Whenever possible, air dry your underwear in direct sunlight. The UV rays help kill bacteria and freshen the fabric.
  2. Use a Dryer with High Heat: If air drying isn't an option, use a dryer on a high heat setting to ensure any remaining bacteria are eliminated.

By following these steps, you can effectively remove odors from your underwear and keep them smelling fresh.

Can I Use Baking Soda To Get Smell Out Of Underwear?

Yes, baking soda is an effective and natural solution for removing odors from underwear. Its alkaline properties help neutralize acidic odors and absorb moisture, making it a powerful deodorizer. To use baking soda, create a paste by mixing it with a small amount of water and apply it directly to the smelly areas of the underwear. Let the paste sit for 15-20 minutes before washing. Alternatively, you can add half a cup of baking soda to your laundry during the wash cycle to boost the odor-fighting power of your detergent. This simple yet effective method can help keep your underwear fresh and odor-free.

Does Bleach Help Get Smell Out Of Underwear?

Bleach can help remove odors from underwear, but it should be used with caution. Chlorine bleach is a powerful disinfectant that can kill odor-causing bacteria and eliminate persistent smells. However, it is only suitable for white, non-delicate fabrics, as it can cause discoloration and damage to colored or delicate materials. For colored underwear, consider using oxygen bleach, which is gentler and safe for most fabrics. Always follow the care instructions on your underwear and dilute the bleach properly before use. While bleach can be effective, it should be used sparingly to avoid weakening the fabric over time.

What Is The Best Type Of Laundry Detergent To Remove Underwear Stains and Smell?

  • Enzyme-Based Detergents: These detergents contain enzymes that break down proteins, fats, and starches, effectively removing stains and odors caused by sweat and bodily fluids.
  • Oxygenated Detergents: Oxygen bleach detergents release oxygen bubbles that lift stains and neutralize odors without damaging clothes, making them ideal for colored and delicate underwear.
  • Activated Charcoal Detergents: These detergents contain activated charcoal, which absorbs and neutralizes odors, providing a deep clean and long-lasting freshness.
  • Detergents with Odor Neutralizers: Formulated with specific odor-neutralizing agents, these detergents target and eliminate stubborn smells, leaving your clothes and underwear smelling fresh.
  • Hypoallergenic Detergents: For sensitive skin, hypoallergenic detergents are free from dyes and fragrances but still effective at removing stains and odors.
  • Sport Detergents: Designed for active individuals, sport detergents are formulated to tackle tough sweat and odor issues commonly found in athletic clothes, including underwear.

Why Does My Underwear Smell Even After Washing?

If your underwear still smells even after washing, several factors could be at play. One common issue is that bacteria and sweat residues may not be fully removed during a standard wash cycle, especially if you're using cold water or a mild detergent. Additionally, your washing machine itself could be harboring bacteria and mold, which can transfer to your clothes during the wash. Overloading the machine can also prevent proper cleaning, as the detergent and water may not reach all areas of the fabric. Finally, using fabric softeners can leave a residue that traps odors. To combat these issues, ensure you're using a high-quality detergent, wash in hot water when possible, and regularly clean your washing machine to prevent bacterial buildup.

Fabric Care Washing Tips For Clean Underwear

  • Read Care Labels: Always check the care labels on your underwear for specific washing instructions to avoid damaging the fabric.
  • Separate Colors: Wash white and light-colored underwear separately from dark colors to prevent color bleeding.
  • Use the Right Detergent: Choose a detergent suitable for your fabric type, such as enzyme-based or hypoallergenic detergents for delicate materials.
  • Wash in Cold or Warm Water: Use cold or warm water for delicate fabrics to prevent shrinkage and fabric damage, while hot water can be used for cotton and other durable materials to kill bacteria.
  • Avoid Overloading the Machine: Ensure your washing machine is not overloaded so that detergent and water can circulate properly and clean your underwear effectively.
  • Skip Fabric Softeners: Avoid using fabric softeners as they can leave a residue that traps odors and reduces the fabric's breathability.
  • Turn Inside Out: Turn your underwear inside out before washing to better target sweat and body oils.
  • Use a Gentle Cycle: Select a gentle or delicate cycle to protect the fabric and elastic bands from excessive wear and tear.
  • Add Vinegar or Baking Soda: Add a cup of white vinegar or half a cup of baking soda to the wash cycle to boost odor removal and soften the fabric naturally.
  • Air Dry When Possible: Air dry your underwear to preserve the fabric and elastic, or use a low heat setting in the dryer if necessary.
  • Clean Your Washing Machine: Regularly clean your washing machine to prevent bacteria and mold buildup that can transfer to your clothes.


Maintaining fresh and odor-free underwear is essential for personal hygiene and confidence. By understanding the causes of persistent odors and following a comprehensive care routine, you can effectively eliminate unwanted smells and keep your underwear in top condition. From pre-treatment techniques and specialized detergents to proper washing and drying practices, these steps will ensure your underwear remains clean and fresh.
