How to Wash Your Bra Properly — The Complete Guide

How often should you wash your bra?

Every time you wear your bra, it absorbs sweat, natural body oils, deodorant and body lotion. These break down the elastic fibres and fabric over time. Regular washing keeps the bra hygienic and prevents premature aging of the materials.

The common mistake is either washing too rarely (bacteria and oils degrade the fabric) or too frequently (overwashing stresses the fibres). 2–3 wears is the sweet spot for most bras in most conditions.

Can you put bras in the washing machine?

Machine washing without a bag is one of the fastest ways to ruin a bra. The underwire bends, hooks snag other garments, and the agitation distorts the cup shape. A mesh lingerie bag solves all of this — the bra is protected inside the bag while the water and detergent still clean it properly.

Machine wash checklist

• Use a mesh lingerie wash bag — one bra per bag if possible
• Fasten the hooks to prevent snagging
• Delicate or hand-wash cycle, max 30°C
• Slow spin — max 400rpm
• Use gentle detergent or lingerie-specific wash
• Remove immediately after the cycle ends — don't leave in a damp drum

How do you hand wash a bra? (The correct method)

Hand washing is the gold standard for bra care — it's gentler on the fabric, extends the life of the bra, and takes less than 5 minutes once you know how.

• 1
  Prepare cool waterFill a clean basin with cool to lukewarm water — maximum 30°C. Hot water damages the elastane and causes colours to bleed or fade.
• 2
  Add gentle detergentA teaspoon of lingerie detergent or a few drops of mild soap. Avoid regular laundry powder — the enzymes and brighteners are too harsh for delicate fabrics.
• 3
  Fasten the hooks and submergeFasten the back hooks before washing. Submerge the bra and gently squeeze water through the fabric for 1–2 minutes. Pay attention to the band lining (absorbs the most sweat) and the cup underside.
• 4
  Never scrub, wring or twistScrubbing distorts lace and mesh. Wringing crushes the underwire and stretches the straps. Gentle squeezing only.
• 5
  Rinse thoroughlyEmpty the basin, refill with clean water, repeat the squeeze until the water runs clear and no soap remains. Soap residue irritates skin and degrades elastic over time.
• 6
  Press excess water out gentlyLay the bra flat on a clean towel, fold the towel over it and press gently. Never wring — it distorts the underwire permanently.

How do you dry a bra correctly?

Tumble drying is the single fastest way to destroy a bra. The heat breaks down elastane fibres, melts the underwire casing and permanently distorts the cup shape. After even a few tumble dry cycles, a bra that used to last 12 months will be dead in 3.

How should you store bras?

Storage matters more than most people realise — especially for moulded or padded cups.

• Stack cups right-side up — never fold one cup inside the other. Folding permanently creases and distorts foam cups.
• Fasten the hooks when storing — prevents snagging on other items in the drawer.
• Don't overstuff the drawer — compressed cups lose their shape.
• For underwire bras — lay flat or upright in the drawer, not folded in half at the gore.

How long should a bra last?

With proper care, a good quality bra worn 3–5 times a week should last 6–12 months. Signs it needs replacing:

• The band rides up at the back — it's stretched and no longer supportive
• You're on the tightest hook and it still feels loose
• The underwire pokes out or digs in at a new spot
• The cups have lost their shape or the moulding is cracked
• The straps won't stay on your shoulders even at their shortest

Does detergent matter?

Yes — regular laundry powder is too harsh for bra fabrics. The enzymes break down delicate fibers and the optical brighteners cause white or pastel fabrics to yellow over time. Use a gentle lingerie detergent or a mild soap (like Woolwash). Bras By MaMloo will be stocking a dedicated lingerie wash as part of our care accessories range — launching soon.
