The method of removing mould from the curtain depends on the condition of the mould and the material of the curtain.

If you are worried about the colour pattern falling off or the material is damaged, it is safe to bring it to a laundry shop.

Use a toothbrush to remove light mould and then wipe it off.

First, hit the mould with a toothbrush to remove it. The mould that only grows on the surface of the curtain can often be cleaned by itself.

If you can’t get rid of the mould just by tapping it with a toothbrush, put a towel on the back of the curtain, apply a mild detergent to the toothbrush, and tap it gently.

When the mould has been removed by the process up to this point, the final step is to finish the mould prevention. Wipe the mouldy areas of the curtain with a towel soaked in rubbing alcohol.

If you can’t use a toothbrush, wash it

Mould on curtains that cannot be removed with a toothbrush alone needs to be washed. You can wash the curtain if it says “Washable” on the washing label of the curtain.

First, put the unhooked curtain in the laundry net. At this time, the curtain folds along the Pleats.

All you have to do is throw the curtain in the laundry net into the washing machine, add oxygen-based bleach, and start washing.

When washing the curtains

  • Keep the water temperature on the washing label
  • Choose a hand-washing course
  • Shorten dehydration time

Try to use a washing method that does not burden the curtains as much as possible.b

After dehydration, you can dry it like ordinary laundry, or if you don’t have enough space, hang it on the curtain rail in your room. Humidity rises just by hanging a semi-dry curtain, so in winter it is two birds with one stone.

Hand wash non-washable Curtains

If the curtain says that it is not possible to wash it in the washing machine but it is OK to wash it in water, prepare a washbasin and a washbasin and wash it by hand.

If you only want to wash it partially, you can also wash it in the washbowl. If you want to wash the entire curtain, you can use the bathtub in the bathroom.

After adding hot water at an appropriate temperature to the washbasin, dissolve the oxygen-based bleach, put a curtain on the hot water, and then wash it by rubbing. For mould that does not come off just by rubbing, let it sit for a while and then rub it with a toothbrush.

After that, rinse it thoroughly, dehydrate it lightly, and dry it in the same way as when using a washing machine.

* When using bleach, be careful not to touch the liquid with your bare hands.

Let’s remove stubborn mould with chlorine bleach

For deep-rooted mould that does not come off even with oxygen-based bleach, use a strong chlorine-based bleach such as mould killer.

However, chlorine bleach can only be used if the washing label on the curtain.

Also, the use of chlorine bleach will damage the fabric, even if it is an enso-salted curtain. If you use chlorine bleach, you need to be careful about that as well.

It’s very easy to remove mould. Simply cover the mouldy area with a towel soaked in chlorine bleach.

Causes of mould growth on curtains and the danger of leaving mould unattended

Moulds nourish dirt and oxygen, such as dust and red, and grow in humid places.

In the case of curtains, there is a window right next to it, so the humidity tends to rise due to the absorption of moisture from the condensation that forms on the window, which is also a major cause of mould growth.

Leaving mould can cause health problems

If left untreated, mould that grows on the curtains can transfer to wallpaper and furniture and grow further.

What’s more, mould on the curtains not only spoils the appearance but can even cause health problems. For example, mould symptoms include an infection called bronchial asthma, and allergic conjunctivitis.

Mould is weakly infectious, so if you are a healthy person, just because you smoke does not mean that something will happen immediately.


  • Baby
  • Elderly
  • People with weakened immunity due to tiredness or illness

In addition, even the most healthy people can be damaged by continuing to smoke for a long period. If you find mould on your curtains, try to deal with them as soon as possible.

Let’s also hold down preventive measures to prevent mould from growing on the curtain

Now that you know what causes mould to grow on your curtains, it’s time to check how to prevent it.

Prevention method 1. Ventilate frequently to prevent condensation

Winter is the season when condensation is likely to occur. In winter, the difference between room temperature and the outside temperature is large, so condensation is likely to occur.

As I mentioned earlier, condensation can also cause mould. Therefore, it is also effective as a preventive measure against the mould to prevent the formation of dew condensation as much as possible.

As long as the air is circulated well, ventilation for about 5 minutes at a time is effective without opening the windows fully. If you’re reluctant to open windows in the winter, you might also want to find out how to circulate air well.

Preventive measures 2. Frequently wipe off condensation on windows and sashes.

No matter how well ventilated, condensation will still occur depending on the environment. If condensation does occur, wipe it off as often as possible.

Films and sprays to prevent condensation are also available on the market, so if there is too much condensation, please consider using special goods.

Prevention 3. Wash the curtains regularly

It’s surprisingly difficult to remove the curtains all over the house, so I think some people may keep hanging them after moving.

However, the more dirt that accumulates, the more likely it is to create a mould-prone environment. If possible, we recommend that you wash your clothes regularly, about once a year.

If it is difficult to wash, it is recommended to spray a spray to prevent mould on the curtain regularly.

However, mould prevention sprays are for prevention only. For mould that has already grown, there is a risk that the spores of the mould will be blown off by the force of the spray rather than being less effective. Let’s watch out.

Prevention 4. Dry the washed curtains quickly

The wet curtain is full of moisture. It’s a state where mould can easily grow, so you want to dry it as soon as possible.

Air conditioners and electric fans are convenient in such cases.

If you use an air conditioner, use the dehumidifying function, and if you use an electric fan, blow the wind on the curtain to dry the wet curtain quickly.

Prevention method 5. Use a mould-resistant curtain

For lace curtains that hang near windows, it’s a good idea to choose products that are antifungal or antibacterial.

Since it is processed, it is a little more expensive than the unprocessed product, but it is recommended to select the one that will be used for a long time, such as a curtain, with an emphasis on functionality.


It is important to deal with mould on the curtain after it grows, but it is more important to prevent and prevent it. Once the mould has been removed and the curtains are clean, please take the above measures to prevent mould growth.
