Mould and mildew in a house is not only unsightly but it also is unhealthy to breathe. Sneezing and sore throat problems are often caused by allergic reactions to mould growing in various indoor areas. The mould that grows on curtains is one of the easiest mould problems to deal with and correct. The most common places where mould grows is dark damp areas of the house. Using a torch, periodically inspect the curtains in the areas of your house that are most prone to mould. Mold will be dark and greenish or black in colour. When you spot mould, take care of it right away.
Take the curtains off the curtain rods.
Place the curtains in the washing machine. Place in a few towels that need to be washed as well. The towels will help clean the curtains during the wash cycle. Set the washer on the hot water setting. Hot water will remove most mould but, if the curtains are very mouldy, throw in a little bleach.
Hang the curtains outside to dry. Remove the curtains from the washer and inspect them for traces of mould after the wash cycle is completed. If there are still traces of mould, place the curtains back in the washing machine and wash them one more time. Once the cycle is completed, hang the curtains outside on a clothes line. Heat and sunlight are also effective at killing mould. Let them dry thoroughly before hanging them back up inside the house.
Rehang the curtains. Check them periodically for signs of mould. If you notice mould starting to come back, spray the area with plain white vinegar. White vinegar is the easiest and most effective way to control mould. It is completely natural and won't harm your pets.
If mould tends to be a persistent problem, consider placing a dehumidifier in the room to remove the moisture.
