How to wash underwear and bras

Biustonosze i bielizna koronkowa wymagające delikatnego prania

A bra is one of the most demanding items of clothing. It has underwires, foam, lace, and an elastic band that can easily be ruined by one improper wash. Good care ensures that a bra retains its shape and support for longer, and lace panties don't lose their charm after a few washes. Here are proven rules for washing lingerie, both by hand and in a washing machine.

Before you start: read the label

The manufacturer's label indicates the maximum temperature, whether it can be machine washed, ironed, and tumble-dried. This is the most important guideline. The following rules are general and useful when the label is gone or when you want to treat your lingerie as gently as possible.

Lace lingerie, which should be hand washed or washed in a laundry bag

How often should you wash a bra?

A bra doesn't need to be washed after every day of wear if it wasn't heavily sweated in. Many people wash it every two or three days of wearing. The rule that truly extends a bra's life: don't wear the same one two days in a row. The elastic band needs a day off to return to its shape. Wash sports bras after every workout. Wash panties after every wear.

Hand washing step by step

Hand washing is the gentlest method and best for lace, padded, and push-up bras.

  1. Fasten the hooks so they don't snag the fabric.
  2. Fill a basin with lukewarm water, about 30°C.
  3. Add a small amount of mild detergent for delicate fabrics or lingerie.
  4. Soak the lingerie for about fifteen minutes.
  5. Gently hand wash, especially under the bust and on the straps, where sweat accumulates. Do not scrub with a brush or wring.
  6. Rinse in cool water until the water runs clear.
  7. Squeeze out excess water by pressing the bra against a towel. Do not wring.

Machine washing: how to do it safely

If the label allows machine washing, follow a few rules:

  • A laundry bag is essential. It protects underwires from slipping out and cups from crushing. Ideally, one bra per bag.
  • Fasten hooks to prevent them from snagging other items.
  • Use a delicate or hand wash cycle, temperature up to 30°C, low spin speed.
  • Wash with similar items: lingerie, thin blouses. Do not wash bras with jeans, towels, or clothes with zippers.
  • Separate colors: dark and intense colors can bleed, especially during the first few washes.

What to avoid

  • Tumble dryer: high heat weakens elastane, deforms foam, and can warp underwires.
  • Chlorine bleach: damages fibers and elastic elements.
  • Fabric softeners: build up on fibers and accelerate loss of elasticity.
  • Twisting and wringing: stretches the material and breaks down the foam.
  • Ironing lace and foam. If the label permits, iron only cotton elements at a low temperature.
  • Too much detergent: detergent residue can irritate the skin and stiffen the fabric.

Drying

Dry bras flat on a towel or drying rack, or hung over the center, i.e., over the bridge between the cups. Do not hang them by the straps, as wet material stretches. Gently reshape padded cups with your hand before they dry. Do not dry lingerie on a radiator or in direct sunlight. Heat weakens elastane, and sun can fade colors.

Cotton lingerie that tolerates higher washing temperatures

Storage

Do not fold padded bras in half, inserting one cup into the other with a crease. It's best to arrange them one behind the other in a drawer, cup in cup. Soft and bralette styles can be folded. Keep lace panties and tights in bags or compartments to prevent them from snagging on hooks. Tips for tights can be found in the guide tights thickness: DEN from 8 to 100.

Washing according to lingerie type

Type How to wash
padded bra, push-up hand wash or in a bag, up to 30°C, dry with reshaped cups
lace bra, bralette preferably hand wash, up to 30°C
sports bra after each workout, in a bag, without fabric softener
cotton panties machine wash according to label, usually 40°C
lace and microfiber panties in a bag, up to 30°C
tights hand wash or in a bag, delicate cycle

Stains and odors: how to deal with them

The most common problem is sweat and deodorant marks on the cups and underarms. Act quickly: the longer a stain remains in the fabric, the harder it is to remove. Soak the stained area in cool water with a small amount of mild detergent and gently wash with your fingers. Hot water can set sweat and blood stains, so always use cold water to remove them. Avoid strong stain removers on lace and colored fabrics. If you want to use them, first test them on an inconspicuous area.

Do not leave sweaty sports bras in the laundry basket for several days. Rinse them after your workout, even if only in clean water, and hang them to dry, then wash them at the earliest opportunity. This prevents the fabric from absorbing odors.

When to replace a bra?

Even with the best care, a bra wears out. Signs that it's time for a new one:

  • the band is loose even on the last, tightest hook,
  • the underwire is poking out of its casing or has bent,
  • the cup has lost its shape, has creases or foam cracks,
  • the straps don't hold their adjustment despite tightening.

This is also a good time to measure yourself again. The guide how to choose a bra size and the calculator on the size chart page will help.
