Because a bra is worn directly against the skin throughout the day, one might assume that washing it after every use is necessary. However, this is not always a strict rule and, counterintuitively, could actually cause premature damage to the garment’s structure.
To provide definitive guidance on how often you should wash your bra, we consulted the cleaning professionals at the Good Housekeeping Institute. Below, you will find their expert recommendations, along with essential tips for maintaining your bra’s shape and longevity.
Optimizing Bra Washing Frequency
If you currently wash your bra after every wear, you are likely overworking yourself and your garment. According to Carolyn Forté, executive director of the GH Institute's Home Care & Cleaning Lab, "Bras can typically be worn a few times—maybe three or even four—depending on the length of wear and whether you have been active or perspired heavily."
Washing too frequently is detrimental because it causes the elastic fibers to break down faster, leading to a loss of elasticity and support. Consider the following key factors when determining if your bra needs a wash:
- ⚠️ Sweat Levels: Any activity involving significant perspiration, whether from exercise or simply hot weather, necessitates immediate washing. Higher sweat means a shorter wear cycle, regardless of how many times you’ve worn it previously.
- ⚠️ Length of Use: The longer the duration of wear, the sooner the bra needs cleaning. Forté notes, "If you're a person who takes your bra off when you get home in the evening, you can probably wash them every three or four wears."
- ⚠️ The Type of Bra: Sports bras used for intense workouts should be washed after every single use to prevent odor buildup and fiber degradation from sweat. Fortunately, most sports bras are made from durable synthetics (nylon, spandex) designed to handle frequent washing.
Maintaining the Longevity of Your Bras
The key to preserving your favorite bras is gentle handling. To keep them in their optimal shape for as long as possible, follow these simple care instructions:
- ✔️ Hand Wash Delicate Fabrics: Certain bras, particularly those made of delicate lace or silk, must be washed by hand. Always check the care label before adding a bra to your machine load.
- ✔️ Use a Mesh Bra Bag in the Washer: If your bra is machine-washable, always place it inside a mesh bra bag (or lingerie bag). This protects the delicate material and prevents straps or hooks from snagging on other laundry items, which is crucial for preserving its shape. Ensure all hooks are closed before washing.
- ✔️ Avoid the Dryer—Air Dry Only: Due to their delicate elastic and foam structures, bras should never be put in the dryer. High heat destroys elasticity. Instead, gently press out excess water and lay the bra flat on a clean surface or hang it up to air dry.
- ✔️ Cycle Through Bras Regularly: Avoid wearing the same bra three or four times consecutively. Instead, rotate between several bras you own. Allowing each bra to "rest" for a day or two helps the elastic recover its shape and significantly reduces strain on the fibers.
Frequently Asked Questions (FAQ) on Bra Care
Why does frequent washing damage a bra?
The primary structural component of a bra is elastic. Frequent exposure to water agitation and detergent causes the elastic fibers to weaken, stretch out, and break down faster than intended, resulting in a loss of fit and necessary support.
What is the benefit of cycling through different bras?
Cycling through bras allows the elastic fibers of the bra you just wore time to fully contract and recover their original shape. Wearing the same bra repeatedly prevents this natural recovery process, leading to quicker stretching and permanent deformation.
Can I use fabric softener when washing my bra?
It is generally recommended to avoid fabric softener on bras, especially sports bras. Softeners can coat the synthetic fibers, reducing their ability to wick away moisture (in sports bras) and can also weaken the elastic over time, which defeats the purpose of the bra's support function.
