You've invested in quality pumping bras, but are you washing them the right way? Most moms don't realize that improper cleaning can destroy the elastic, warp the cups, and shorten your bra's lifespan by months. Learning how to wash your pumping bras correctly keeps them supportive, fresh, and ready for daily use without spending a fortune on replacements.
How to Store Your Pumping Bras
Storing your pumping bras the right way is just as important as washing them. How you keep them between uses can make a big difference in their shape, stretch, and how long they last.
-
Maintain the Cups’ Shapes: Do not crush or fold the cups of your pumping bra. This can alter their shapes and create creases. Instead, store bras in a flat position with the cups up, stack them together, or hang them from the center gore point using a padded hanger when storage space is limited.
-
Store in a Cool, Dry Place: Heat and moisture will cause elastic to deteriorate. Keep pumping bras out of the way of heat sources and damp bathrooms. Storing them in a bedroom drawer is a great option. If you live in a humid climate, toss a few packets of silica gel in the drawer.
-
Sorting Clean and Used Bras: Clean bras should always be stored separately from used ones. This can easily be achieved by setting up a box for storing used bras or allocating the “clean” and “worn” sections of a drawer.
-
Do Not Overfill: Overfilling a drawer can cause cups to flatten and fabric to stretch. Allow space between bras. Drawer dividers assist in maintaining order.
How Often Should You Wash Your Pumping Bras?
A common question among new mothers is how often to wash their pumping bras. Pumping bras require extra care because they come into contact with breast milk and are used every day, in contrast to ordinary bras that can be worn multiple times before needing to be washed.
-
Every 2-3 Wears Normally: Wash your pumping bra after two to three wears to prevent spills. This prevents excessive washing from wearing out the elastic too quickly and keeps it fresh. You should wash your bras roughly twice a week if you switch between different styles.
-
Right Away After Milk Spills: Wash your pumping bra right away if breast milk gets on it. The proteins and fats in breast milk encourage the growth of germs on textiles, which results in unpleasant odors and skin discomfort. Leaks of any size must be cleaned right away.
-
Daily for Heavy Pumpers:Wash your bra every day if you pump exclusively or do 6 to 8 sessions a day. More bacteria are produced by dampness and frequent wear. To ensure you always have clean bras on hand, rotate three or four.
-
More Often When It's Hot: During the summer, wash your pumping bra after every 1 to 2 wears because hot weather causes more perspiration. The heated environment created by pumping, combined with perspiration, accelerates the growth of bacteria.
-
Before First Wear: Always wash new pumping bras before using them. Manufacturing and shipping leave residues and dust on the fabric that should be removed before the bra touches your skin.
-
After Exercise or Sweaty Days: If you work out or have a really sweaty day while wearing your pumping bra, wash it after that single wear. Activity level affects how much bacteria builds up in the fabric.
Pumping Bra Washing Guide:
Quick Frequency Reference
For everyday use without spills, wash after 2-3 wears to maintain hygiene while preserving elasticity.
Wash immediately when breast milk contacts the bra to prevent bacteria growth and odors.
With 6-8 pumping sessions daily, wash your bra every day. Keep 3-4 bras in rotation.
Increase washing frequency during warm months due to perspiration and humidity.
Wash after any physically demanding activities or sweaty days, regardless of milk exposure.
Always wash new pumping bras to remove manufacturing residues and soften fabric.
How to Wash Pumping Bras by Hand
Hand washing helps protect the shape, elastic, and fabric of pumping bras. Follow these steps for a proper clean:
Step 1: Rinse and Pretreat Stains
- Rinse the bra under cold water to remove fresh milk spots.
- Check inside the cups, along seams, and under the straps for dried milk stains.
- Gently scrape off dried milk with your fingernail or a soft cloth.
- Apply a small amount of gentle stain remover or liquid detergent directly to the spots.
- Lightly brush with a soft toothbrush in small circles (avoid scrubbing hard).
- Let it sit for about 10–15 minutes.
Step 2: Prepare a Cool Wash Basin
- Fill a clean sink or basin with cool or lukewarm water.
- Avoid hot water—it damages elastic and sets protein stains.
- The water should feel neutral or slightly warm to your hands.
Step 3: Add Gentle Detergent
- Mix in 1–2 teaspoons of mild liquid detergent.
- Stir with your hand until evenly dissolved and lightly sudsy.
- Do not use fabric softener or bleach.
Step 4: Soak the Bra
- Immerse the bra completely in the water.
- To allow the fabric to absorb water, gently press it down.
- Allow it to soak for ten to fifteen minutes.
- Soak for up to half an hour if the smell is severe.
- For odor buildup, it is optional to add 1-2 teaspoons of white vinegar (do not mix vinegar and bleach).
Step 5: Gently Clean the Fabric
- Instead of twisting or wringing, lift and press the bra in the water.
- Pay attention to the straps, cups, and underband; these are where perspiration and milk are collected.
- To remove residue, gently massage the fabric against itself if necessary.
Step 6: Rinse Thoroughly
- Empty the basin and fill it with fresh, chilled water.
- To get rid of the soap, submerge the bra and squeeze it lightly.
- Repeat one or two times until there are no more suds and the water flows clear.
- Ensure that no detergent residue remains, as it may cause skin irritation.
Step 7: Remove Water and Shape
- Avoid wringing the bra.
- To absorb the water, place it on a fresh towel, fold the towel over it, and gently press.
- For quicker removal, you can choose to spin in a salad spinner.
- If necessary, use your hands to reshape molded cups.
- Away from heat or direct sunlight, leave flat or hang to dry.
Can You Wash Pumping Bras in the Washing Machine?
Yes, you can wash pumping bras in the washing machine if you take the right precautions to protect them. Machine washing is faster than hand washing, but it requires careful preparation to avoid damage.
Always fasten all hooks and closures before washing to prevent snagging, and place your bras in a mesh lingerie bag to protect them from the machine drum and other clothing. Use the delicate or gentle cycle with cool water, as hot water breaks down elastic fibers. Most pumping bras can handle occasional machine washing when you follow these steps. However, hand washing remains gentler and helps your bras last longer. If your bra has heavy padding or the elastic is already wearing out, stick with hand washing instead.
How to Wash Pumping Bras in the Washing Machine
Time is saved by machine washing, but care must be taken to preserve the fabric and elastic. To safely clean your pumping bras, follow these steps:
Step 1: Fasten All Hooks and Closures
All hooks and clasps should be closed before washing to prevent snagging on other fabrics or twisting while being washed. This keeps the hardware from bending and stops the straps from straining.
Step 2: Place Bras in a Mesh Lingerie Bag
Put one bra, or as many as two, inside a mesh lingerie bag. Secure it with a knot or a zip. By forming a barrier between the bra and the drum, the bag lessens friction and pulling. Use a fresh pillowcase and tie the end if you don't have one.
Step 3: Wash Only 2-3 Bras at Once
Only a few bras should be washed at once. Elastic deteriorates more quickly when there are too many pieces because they can twist and rub. The detergent circulates and cleans more evenly when small loads are used.
Step 4: Select the Delicate Cycle with Cold Water
Set the water to cold and choose the delicate or gentle cycle. Slower agitation and spin are used in delicate settings to preserve the bra's structure. Protein stains are prevented from settling, and elastic damage is avoided with cold water.
Step 5: Use Mild Detergent Only
Apply a tiny bit of mild liquid detergent. Instead of pouring it directly onto the bra, pour it into the dispenser. Avoid using fabric softener and bleach since they both degrade elastic and leave behind residue that can irritate skin.
Step 6: Separate by Color
To prevent color transfer, wash light and dark bras separately. To avoid dye bleed, wash a brand-new bra in similar colors for the first few cycles.
Step 7: Reshape Molded Cups After Washing
Remove the bras as soon as the washing is finished. When the molded cups are still wet, gently press and smooth them back into place. This aids in their proper drying form.
How to Dry Your Pumping Bras
Drying your pumping bras correctly is just as important as washing them properly. The drying method you choose directly affects how long your bras maintain their shape, elasticity, and support.
-
Never Use the Dryer: The high heat from the dryer damages the elastic fibers in your bra, causing them to lose their stretch and support. Even a single dryer cycle can cause permanent damage to the band and straps, leaving your bra loose and unsupportive. The tumbling action also distorts molded cups and can cause underwires to shift or poke through the fabric.
-
Air Dry Flat or Hanging: Lay your bras flat on a clean, dry towel or hang them to air dry in a well-ventilated area. If hanging, drape the bra over a drying rack or hanger by the center gore (the piece between the cups) rather than by the straps. Hanging by the straps can stretch them out while the bra is wet and heavy.
-
Reshape Cups While Damp: If your bra has molded or padded cups, reshape them with your hands while the fabric is still damp. Gently press the cups back into their rounded shape and smooth out any creases that formed during washing.
-
Choose a Cool, Dry Location: Dry your bras away from direct sunlight and heat sources, as excessive heat weakens elastic and fades colors. A bathroom with good airflow, a bedroom, or a laundry room works well. Avoid drying bras near radiators, heating vents, or in direct sun.
Most bras will be completely dry within 12-24 hours depending on humidity levels and fabric thickness. Following these drying methods keeps your pumping bras in good condition for months of comfortable use.
What Detergent to Use When Washing Pumping Bras
When washing pumping bras, stick to a mild, gentle detergent without dyes, fragrances, or harsh chemicals. Hypoallergenic formulas made for delicate fabrics or sensitive skin are best—they clean well while keeping your bra soft and stretchy.
Go Gentle on Your Bra (and Your Skin)
Choose a dye-free, fragrance-free, hypoallergenic detergent. Regular detergents can be tough on elastic and may irritate sensitive postpartum skin. Gentle care helps bras with stretch fabrics—like the Momcozy 4-in-1 Hands-Free Pumping Bra—hold their shape and comfort longer.

Avoid Bleach and Fabric Softener
Skip the bleach and the fabric softener altogether. The fabric softener can coat the fibers and reduce the elasticity of the material, as bleach will break down materials that have stretch. Both of these things can reduce the life of pumping bras.
Lingerie Washes Are Great
Delicate detergents work beautifully on pumping bras. They are designed to handle stretch materials and won't strip the skin of its natural oils. They can be a great addition to your laundry routine, but only if you already have a gentle detergent at home.

Don't Overdo the Soap
Excess detergent doesn't translate to clean bras. Too much detergent will create residue that causes the fabric to become stiff. Use the recommended detergent or even less to keep your pumping bra soft.
The effort you're putting in for yourself means that a little bit of gentle treatment goes a long way. Opting for a detergent that avoids ingredients like chlorine or other strong chemicals can help your soft and stretchy bras stay comfortable and supportive through multiple uses, as in the case of the Momcozy 4-in-1 Hands-Free Pumping Bra.
Take Care of Your Pumping Bras for Better Support
Be gentle with your pumping bras—cool wash, gentle soap, and air-drying are the basics. Regular cleaning and the right storage help them last longer and stay comfy. Treat them right, and they’ll keep supporting you every day while you're breastfeeding.
