How to Wash Net Curtains to Keep Them White

To keep net curtains white, machine wash them on a delicate cycle at up to 30 °C and hang them to dry straight after washing. At the window they gather dust, smoke and kitchen grease and turn grey. One mistake with heat or the dryer can shrink them for good. We cover washing step by step, whitening with household products and when to call in professionals.

How to Wash Net Curtains to Keep Them White

Washing net curtains in a machine, step by step

Most net curtain fabrics can go in an automatic washing machine. The exception is curtains whose care label allows dry cleaning only. Here is how to machine wash net curtains in seven steps so they do not crease or tear.

  1. Take the curtain down from the rod and shake the dust out of it on the balcony or outdoors.
  2. Remove the hooks, rings and all metal parts. In the machine they would tear the fabric and could even damage the drum.
  3. Read the care label, which is usually sewn on near the heading tape. The manufacturer states the maximum temperature and the right cycle there.
  4. Fold the curtain loosely into a mesh laundry bag and do not squash it into a ball.
  5. Fill the drum no more than halfway and always wash only the curtains from one window at a time.
  6. Choose a delicate cycle or a curtain cycle at up to 30 °C.
  7. Set a short spin at low speed, around 400 rpm.

An overloaded drum and high spin speeds leave sharp creases in thin fabric that stay after drying. So it pays to wash in smaller loads, even if it takes longer. Take the curtain out of the machine straight after washing and hang it up so it does not crease.

Temperature and cycle by fabric

For most net curtains 30 °C is the safe limit. Choose a higher temperature only when the label clearly allows it.

  • Wash voile, chiffon and polyester curtains on a delicate cycle at up to 30 °C. In hot water synthetic fibres lose their shape for good.
  • Linen and cotton shrink more than synthetics, so they need a low temperature and careful drying. Linen also creases naturally and will not be perfectly smooth even after ironing.
  • Wash lace and embroidered curtains by hand in lukewarm water, or in a bag on a delicate cycle. A few drops of liquid detergent are enough. Do not wring them; let the water drip off on its own.

Detergent and fabric softener

For white net curtains use a liquid detergent for delicates or a special curtain detergent. Wash coloured ones separately with a colour detergent so the pattern does not fade. Use only as much detergent as needed, as its residue stays in the fabric. Skip fabric softener. Most guides warn that it weighs the fibres down, so the curtain lets through less light and may turn yellow over time.

Drying and ironing

To stop the curtain creasing, hang it on a drying rack straight after washing and let it dry spread out. Hanging loosely without folds, it dries almost smooth and usually you will not need to iron it. Skip the tumble dryer, as hot air shrinks the curtain and twists the heading tape. If the fabric still creases, iron it on the lowest setting through a cotton tea towel or smooth it with a steamer. Voile and synthetics only need steaming from the back. With the window slightly open the curtain dries faster.

How to whiten net curtains

Before washing, soak grey or yellowed net curtains for several hours, ideally overnight, in a solution of a household product. Let the curtain lie loosely in the bath or a large basin, then wash it as described above. Test the solution on a small piece of fabric at the hem first. Do not use chlorine bleach on net curtains, as it weakens the thin fabric, which then tears easily.

Why net curtains turn yellow and grey

How to whiten yellowed net curtains, and where to start with grey ones, depends on the cause.

  • Cigarette smoke turns net curtains yellow fastest.
  • A radiator under the window heats the fabric, so the curtain above it yellows sooner.
  • In the kitchen, steam and grease from cooking settle right in the fibres.
  • Street dust gets into the curtain through the open window and the white gradually turns grey.
  • Fabric softener and too much detergent stay in the fabric and turn yellow over time.

Whitening net curtains with household products

You will find the products in the table in almost any home. We do not give amounts, because guides differ on them by a factor of several, and soaking long enough matters more.

ProductHow to use itWhen it helps
Table saltDissolve in water and soak the curtains for several hours before washingYellowed curtains
Baking sodaSoak overnight, or add to the machine with the detergentOdours, for example from smoke
Baking powderStir into a bath and soak the curtains for several hours or overnightVery grey curtains

You can wash net curtains with baking soda even without soaking, just add it to the machine.

When to leave it to professionals

Net curtains whose label allows dry cleaning only belong at the dry cleaner's. Also hand them to professionals when they are long and heavy or when whitening at home did not help.

At VESTA we offer net curtain washing in Prague with steaming and ironing. On request we take the curtains down ourselves and hang them back. We collect them from your home and return them after washing. Washing usually takes 5 working days, express within 48 hours for an extra fee. We do not whiten curtains, but after professional washing they are noticeably lighter. If they stay grey, we sew new net curtains made to measure.

Frequently asked questions

How often should you wash net curtains?

It depends on the room. In the kitchen and where people smoke, wash net curtains more often, as grease and smoke build up in them quickly. You can tell it is time to wash them by a grey tinge or a smell. Wash them more often in a home with an allergy sufferer or pets, too. Between washes it is enough to vacuum the curtain gently with an upholstery nozzle or shake the dust out of it.

Why did my net curtain shrink after washing?

Most often because of a higher temperature than the fabric can take, or a tumble dryer. Linen and cotton are at greater risk, and voile can shrink above just 30 °C. Shrunk polyester will not go back to its original size, so always follow the temperature on the label and dry the curtain on a line, not in a dryer. Shrunk linen can be partly stretched back by steaming or ironing while damp.

Can I wash net curtains together with curtains?

Better not. Curtains are heavier and often a different colour, so a white net curtain would turn grey in the same load. Makers of curtain fabrics also recommend washing them separately so other items do not pick up their dye, and the two fabrics may shrink differently. So a net curtain sewn to a curtain is better left to professional washing, which we also offer in Prague. Wash white net curtains separately from coloured ones too.
