Why Do Yellow Stains Remain on the Crotch of Your Underwear After Washing?
Yellow stains on the crotch of underwear are a common problem that many people face, even after washing. Several factors contribute to these stubborn stains remaining on the fabric. Here are the main reasons why yellow stains persist and how to get rid of them:
1. Sweat and body oils cause yellow stains that remain on the bottom of underwear after washing.
Yellow stains often occur because of sweat and body oils that accumulate on the fabric, especially in the crotch area. Sweat contains salts, acids, and proteins that can react with the fabric, causing stains that are difficult to remove completely—especially if not treated immediately.
2. Washing with Water That’s Too Hot
Washing underwear in water that’s too hot can make yellow stains even harder to remove. High temperatures help oils and sweat bond tightly to the fabric fibers, making them difficult to eliminate with cold or lukewarm water.
3. Using the Wrong Detergent
Detergents that aren’t strong enough or not suitable for the fabric may fail to fully clean the stains, especially yellow ones caused by sweat and body oils. Some detergents only clean the surface of the fabric and don’t penetrate deeply into the fibers to remove tough stains.

4. Overuse of Fabric Softener
While fabric softener makes clothes soft and fragrant, overusing it can reduce the effectiveness of your detergent and cause stains to stick longer. Fabric softener can create a protective layer on the fabric, preventing stains from being effectively removed.
5. Not Treating Stains Immediately
If you don’t wash your underwear right after use or fail to treat stains like sweat or body oils immediately, these stains will have time to bond to the fabric and become harder to clean once they dry.
*) How to remove yellow stains left on underwear after washing
- Use a Specialized Detergent: Choose detergents specifically designed to tackle yellow stains or sweat. These products have special formulas to remove stubborn stains effectively.
- Soak Underwear Before Washing: Soak your underwear in cold water mixed with a bit of white vinegar or baking soda for about 30 minutes to help break down the yellow stains.
- Wash with Cold Water: Wash your underwear in cold or lukewarm water. Avoid hot water, as it can cause stains to set deeper into the fabric.
- Use Stain Remover: Stain removers designed for clothes can help remove yellow stains. Apply the stain remover directly onto the stain before washing for optimal results.
- Check Regularly: During the wash, check your underwear to ensure that all stains have been removed completely.
Conclusion
Yellow stains in the crotch area of underwear are primarily caused by sweat and body oils. Incorrect washing techniques or failure to treat stains immediately can cause them to persist. By following the proper stain treatment methods, you can keep your underwear clean and fresh.
