Let’s face it: hand-washing clothes is a chore most of us want to skip. You want your lingerie to stay clean and supportive, but scrubbing them in the sink takes time you don’t have. The good news is that you can use the machine if you follow the right steps.
We have put together the ultimate guide on how to wash bras in the washing machine without ruining the elastic or bending the underwire.
Key Takeaways
- Protection is key: Always use a mesh laundry bag or a secured pillowcase to prevent snagging.
- Cycle settings: Only use the delicate cycle with cold water to preserve elasticity.
- Frequency: Wash standard bras every 2 to 3 wears; wash sports bras after every workout.
- Drying rules: Never use the dryer. Air dry flat or hang them by the center gore, not the straps.
How Often Should You Wash a Bra?
You should wash your standard bras after every 2 or 3 wears. Even if you don’t feel sweaty, your body transfers natural oils and dead skin cells to the fabric throughout the day. Bacteria love these environments, and leaving them too long can lead to body acne, rashes, or unpleasant odors.
However, “one wear” means a full day. If you only wore it for an hour to run an errand, you can likely put it back in the drawer.
Wash your bras more frequently during the summer or if you have a physically active job. Sports bras possess different rules. You must wash or rinse sports bras after every single workout. Sweat penetrates the tight synthetic fibers quickly, which degrades the elastic and breeds bacteria.
Can You Put Bras In the Washer?
Yes, you can put most bras in the washing machine, but there is a catch. Machine washing is rougher than hand washing and can shorten the lifespan of your lingerie over time. Always check the care label first, as specific materials require different methods.
Quick Guide: Washing Machine Safety by Bra Type
| Type of Bra | Machine Wash Safe? |
| Underwire bras | Risky. The agitation can bend the wire or cause it to poke through the fabric. Hand washing is safer. |
| Padded/Push-up bras | Risky. The machine can dent or twist the foam cups permanently. |
| Wireless / Bralettes | Yes. These are generally safe for the delicate cycle. |
| Silk or Lace | No. Always hand wash these delicate fibers to prevent tearing. |
| Sports bras | Yes. These are built for durability and are machine safe. |
How to Wash Bras In a Washing Machine
Hand washing is the gold standard, but modern life is busy. If you need to use the machine, the secret is protection. You must use a mesh lingerie bag. This bag creates a barrier that stops hooks from snagging other clothes and prevents the straps from getting stretched out around the agitator.
Follow these steps to keep your intimates in top shape.
What You’ll Need
- Mild laundry detergent (alcohol-free)
- Mesh laundry bags
- Clean dry towels
- Hangers or a drying rack
1. Prep the Bras
Always hook the back clasps together before washing. If you leave them unhooked, the metal hooks act like little grappling hooks that will snag on lace, other clothes, or the mesh bag itself.
Place your bras inside the mesh bag. Do not overstuff the bag; the water and detergent need room to circulate.
2. Select the Settings
Set your washing machine to the Delicate or Hand Wash cycle. Use Cold Water only. Hot water breaks down the spandex and elastic that gives the bra its support.
Add a small amount of mild detergent. Do not use fabric softener. Softeners coat the fibers and ruin the moisture-wicking properties of the fabric.
3. Dry Properly
When the cycle ends, take the bras out immediately. Do not put them in the dryer. The heat will destroy the elastic and ruin the shape of the cups.
Instead, gently squeeze excess water out with a towel (do not wring or twist). Reshape the molded cups with your fingers while they are still damp. Hang them to air dry on a hanger or lay them flat on a drying rack.
Pro Tip: Never hang a wet bra by its straps. The weight of the wet water will stretch the straps out. Hang it by the center gore (the piece between the cups) over the hanger or drying bar.
How Do You Wash Bras Without a Mesh Bag?
If you don’t have a mesh bag handy, grab a cotton pillowcase. Place the bras inside the pillowcase and tie the top closed with a hair tie or use a heavy-duty safety pin. This provides a similar protective buffer against the rough tumbling of the machine.
Can You Put Bras In the Dryer?
No, you should never put bras in the dryer. The high heat effectively cooks the elastic, causing it to become brittle and snap. Heat also warps the underwire and causes padding to lump together.
Air drying is the only safe method. It usually takes about 24 hours for a padded bra to dry completely, so make sure you rotate your wardrobe.
How to Hand Wash Bras
If you have an expensive lace bra or a favorite piece you want to keep forever, hand washing is the way to go. It is gentle, effective, and actually pretty fast once you get the hang of it.
- Time: 20 minutes (plus drying time)
- Difficulty: Easy
What You’ll Need
- Gentle laundry detergent (or baby shampoo)
- 2 clean towels
- Hangers
1. Create a Sudsy Bath
Plug your clean bathroom sink or use a small plastic basin. Fill it with cool to lukewarm water. Add a tablespoon of mild detergent. Swirl the water with your hand to create suds.
2. Soak and Swirl
Submerge your bras in the water. Let them soak for 15 to 20 minutes. This allows the soapy water to penetrate the fabric and break down oils without any rough agitation.
3. Agitate Gently
Use your hands to gently massage the cups and bands. rubbing the fabric against itself lightly to remove stubborn dirt. Focus on the band and the area under the arms where sweat accumulates.
4. Rinse Thoroughly
Drain the dirty water and refill the sink with cool, fresh water. Swirl the bras to rinse. Repeat this process until the water runs clear and no soap bubbles remain.
5. Remove Water
Lift the bra out of the water and gently press it between your hands. Do not wring it like a dishrag, as this snaps the fibers. Lay the bra on a dry towel, cover it with a second towel, and press down to absorb moisture. Reshape the cups and hang to dry.
Tips For Caring For Bras
A few small habits can double the life of your lingerie.
- Rotate your wear: Avoid wearing the same bra two days in a row. The elastic needs a “rest day” to snap back to its original shape.
- Store correctly: Stack molded cup bras inside each other in your drawer. Do not fold them in half or invert one cup into the other, as this causes permanent creases.
- The Salad Spinner Hack: If you hate hand washing, use a salad spinner. Place the bra inside with water and soap, spin gently to agitate, drain, and spin again with fresh water to rinse. It acts like a mini, manual washing machine!
- Shower wash: In a rush? Wear your bra into the shower. Lather it up gently while you wash, rinse it, and hang it to dry immediately after.
When Should You Replace a Bra?
Most bras have a lifespan of about 8 to 12 months with regular wear. It is time to toss it if the band rides up your back, the straps fall down constantly (even when tightened), or the underwire is poking through. If the cups gap or the fabric looks rippled, it is no longer giving you the support you need.
FAQs
What Kind of Detergent Should You Use For Bras?
You should use a mild liquid detergent specifically formulated for “delicates.” Avoid heavy-duty powders or detergents containing enzymes and bleach, as these can eat away at silk and spandex fibers over time.
Do You Have to Wash Bras In Cold Water?
Yes, cold water is essential. Hot water breaks down the elasticity in the band and straps, which ruins the fit. Cold water cleans effectively while preserving the structural integrity of the garment.
Can I Wash My Bras With Vinegar?
Absolutely. White vinegar is a great natural deodorizer. You can add a half-cup to the rinse cycle (or your hand-wash basin) to help strip away detergent buildup and eliminate sweat odors without using harsh chemicals.
How Many Bras Should a Woman Have?
While there is no magic number, a good rule of thumb is to own 5 to 7 everyday bras. This allows you to rotate them daily, giving each bra a chance to “rest” and regain its elasticity between wears, which helps them last longer.
Should You Wash New Bras Before Wearing?
Yes, always wash new garments. Manufacturing residues, excess dyes, and germs from other shoppers who tried them on can linger on the fabric. A quick wash ensures it is clean against your skin.
How Do I Get the Sour Smell Out of My Bra?
If your bra smells sour even after washing, it likely has trapped bacteria or fungus. Soak the bra for 30 minutes in a solution of one part white vinegar and four parts cool water. Rinse thoroughly and dry it in direct sunlight, which helps kill lingering bacteria.
Can I Wash Bras with Other Clothes?
Yes, you can wash bras with other clothes, provided they are lightweight items like t-shirts, underwear, or pajamas. Avoid washing bras with heavy items like jeans, towels, or bedding, as the heavy fabrics can crush the bra cups and damage the underwire during the spin cycle.
Keep Your Support System Strong
Washing bras in the washing machine doesn’t have to be a disaster. The trick is simply minimizing heat and friction. By using a mesh bag, sticking to cold water, and skipping the dryer, you can get clean lingerie without the hassle of hand scrubbing.
Treat your bras well, and they will support you comfortably for months to come. Now that you know the drill, go throw that load in the wash!
