Why it’s Important to Wash Blackout Curtains Regularly

When it comes to keeping your home clean and your family healthy, there are few things more important than washing your blackout curtains regularly. Here’s why:

Improve the air quality 

Curtains are notorious for collecting dust. Dust mites, which are tiny creatures that thrive in dusty environments, are a common cause of allergies and asthma. By washing your blackout curtains on a regular basis, you can help reduce the amount of dust in your home and improve the air quality for your family.

Keep your family safe

In addition to dust, curtains can also collect dirt, pollen, and other allergens. If these buildup on your curtains, they can trigger allergies or asthma attacks when you least expect it. By washing them regularly, you can help remove these allergens and keep your family safe.

Extend lifespan

Finally, washing your blackout curtains helps to extend their lifespan. Curtains are an investment, and by taking care of them, you can ensure that they last for many years to come.

What Materials Are Used in the Making of Blackout Curtains?

Blackout curtains are made of thick, heavy fabric that is usually lined with a light-blocking or reflective material. The most common blackout curtain fabrics are polyester, nylon, and acrylic. Blackout curtains can also be made from natural fibers such as wool or cotton, but these materials are less effective at blocking out light.

Blackout fabric can also be embossed with decorative patterns or even quilted for extra insulation. Many blackout drapes also come with a blackout liner to provide additional light-blocking capabilities and improve their insulating properties.

Preparation: Removing and Testing Contaminant Before Washing

If you plan on washing your blackout curtains, it is important to first remove any contaminants that may be present. This can be done by gently vacuuming the curtains with a soft brush attachment. Alternatively, you can spot clean the curtains with a damp cloth.

Once the curtains are free of any dirt or debris, it is time to test for colorfastness. To do this, simply wet a small section of the fabric and rub it with a white cloth. If any color bleeds onto the white cloth, then the fabric is not colorfast and should not be washed. 

Once you have verified that the curtains are colorfast, then you can proceed with washing them.

Start by reading the care instructions on the label of your blackout curtains. Some curtains may require a gentle cycle while others may need to be washed cold or warm, so make sure you know what is best for your curtains before you proceed.

Once it is completed washing, transfer the curtains over to the dryer. Set it on low heat or air fluff setting only and take them out as soon as they are done drying. Do not let the curtains remain in the dryer for too long as this can cause fading and damage. 

Once dry, put your freshly cleaned blackout curtains back up!

Drying and Re-Installing Your Blackout Curtain

Assuming your blackout curtains are made of a washable fabric, start by checking the care label for washing instructions. If the care label says to dry clean only, then you will need to take them to the dry cleaners. Otherwise, you can wash them at home using cold water and a gentle cycle on your washing machine.

Once the curtains are washed, it’s time to dry them. Hang them up on a clothesline or drying rack and allow them to air dry completely. Do not put them in the dryer, as this could damage the fabric.

Once the curtains are completely dry, you can re-install them on your windows. Make sure they are hung evenly and that all of the hooks or rings are properly in place. 

Test the curtains by closing them and making sure they are blocking out all of the light. If not, you may need to apply additional layers of curtain liner or blackout fabric.



Can I wash blackout curtains in the washing machine?

Assuming your blackout curtains are made of a washable fabric, you can absolutely wash them in the washing machine! Just be sure to use cold water and a gentle cycle, as hot water and/or a heavy-duty cycle could damage the fabric. You may also want to air dry your curtains instead of putting them in the dryer, as the heat from the dryer could shrink or damage the fabric.

If you have blackout curtains that are made of a washable fabric, you can absolutely put them in the washing machine! Just be sure to use a gentle cycle and cold water, and don’t forget to line dry or tumble dry on low heat to prevent shrinkage. If your blackout curtains are not washable, you can spot clean them with a damp cloth and some mild detergent.

Can curtains go in the washing machine?

If your curtains are made of a machine-washable material, then yes, you can put them in the washing machine! Just be sure to use cold water and a gentle cycle. You may also want to wash them with similar items, such as other curtains or pillowcases. When putting your curtains in the machine, be sure to use a mesh laundry bag to protect them from snagging or tearing.

After washing, you can either hang your curtains back up or put them in the dryer on a low heat setting. Again, using a mesh bag will help protect them from damage. Once they’re dry, give your curtains a good shake before hanging them back up – this will help get rid of any wrinkles or creases.

If your shades are made of a delicate fabric or if they have special features like grommets, you may need to take them to a professional cleaner.

Why do my blackout curtains smell?

If you’ve ever noticed your blackout curtains giving off an unpleasant smell, chances are it’s because they’re in need of a good wash. While most people don’t think to wash their curtains on a regular basis, doing so can help to keep them smelling fresh and looking like new.

So, why do my blackout curtains smell? There are a few possible reasons:

1. They haven’t been washed in a while – If it’s been awhile since you last washed your blackout curtains, they may be starting to develop a musty smell. This is especially true if they’re made of natural fibers like cotton or linen. To get rid of the smell, simply wash them according to the care instructions (most can be machine-washed).

2. They were stored improperly – If you stored your blackout curtains in a humid or damp environment, they may have picked up some mildew or mold spores. These can cause an unpleasant smell that will only go away once the curtains are washed. Again, follow the care instructions when washing to ensure that the mold or mildew is completely removed.

3. They’ve come into contact with something smelly – If your blackout curtains have come into contact with something that has an odor (smoke, pets, strong perfumes, etc.), that odor can transfer to the fabric and cause them to smell bad. In this case, you’ll want to spot clean the affected area first before putting them in the washing machine.


Washing your blackout curtains is an essential part of keeping them in good condition and making them last longer. By following these tips and tricks, you can be sure that you are getting the most out of your purchase. It doesn’t matter if you hand washed or used a machine – by taking care with your gentle detergent, warm water, and low spin cycle setting; you can get the best cleaning results possible so that they look like new again.
