5. Expert advice
Ms. Li, an underwear care expert, mentioned in a recent interview: "The yellowing of bras often starts from the seams and buckles. These areas are more likely to accumulate sweat and grease. It is recommended that consumers pay special attention to these areas when cleaning, and can use a soft-bristled toothbrush for local cleaning."
Dermatologist Dr. Wang also reminds: "Wearing a yellowed bra for a long time may irritate the skin and lead to allergies or dermatitis. When you find that the bra is obviously yellowed and cannot be cleaned, you should replace it in time."

1.Think yellowing is just a cosmetic issue:In fact, yellowing means bacterial growth, which may affect health.
2.Treat all yellow stains with bleach:Bleach can damage the elastic fibers and cause the bra to deform.
3.Ignore bra shelf life:Even if the appearance is intact, the protective performance of a bra that has been used for more than one year has declined significantly.
From the above analysis, it can be seen that yellowing of bras is the result of a combination of factors. Adopting correct cleaning and maintenance methods can effectively extend the service life of your bra and maintain its good appearance and functionality.
