When Was the Last Time You Cleaned Your Curtains? Here’s How—and How Often—You Should Do It

The right curtains can complement a room’s design, provide privacy and insulation, and filter or block sunlight. However, dirty curtains can trap dust, allergens, and odors, creating an unhealthy environment that can also be unsightly and create the impression that your home is unkept.

Like other home components, your curtains should be cleaned on a regular basis. But cleaning your curtains the wrong way could ruin them. So, here’s everything you need to know about cleaning different types of curtains with various methods.

How Often Should You Clean Curtains?

The frequency you should clean your curtains can depend on many factors—and Marla Mock, president at Molly Maid, a Neighborly company, says this includes where you live and how much dirt your house is exposed to. “For allergy sufferers, it’s wise to vacuum or wash curtains every one to two months to keep dust levels low,” she says. And if you have pets, Mock recommends cleaning curtains every three to four months to prevent fur build up.

If you don’t have pets or an extra-dusty home, Alessandro Gazzo, cleaning expert at Emily’s Maids, recommends steam cleaning once or twice a month. Consider vacuuming the curtains once or twice a month as well. If you plan to wash the curtains in the machine—or tub—Gazzo recommends every 8 to 12 weeks.

Curtain Cleaning Methods

Curtains are available in a variety of materials, including polyester, velvet, wool, linen, and silk.  And according to Mock, the correct cleaning method will depend on which material the curtain is made of. “Some materials will require special care, such as dry cleaning, while other materials are more durable and can be hand washed,” she says.

In addition to material type, Mock explains that the level of stains or dirt should also be taken into consideration. “And, it’s always important to check the care label before cleaning,” she tells me.

These are some of the cleaning methods to consider.

Vacuum

Vacuuming your curtains regularly can help cut down on dust and buildup, Mock explains. This method works for most curtain types, but you should use extra caution when vacuuming delicate fabrics, like silk.

Steam

Gazzo, says his favorite way to clean curtains is to regularly use a garment steamer. “With a garment steamer, you can avoid having to remove the curtains, wash them, wait for them to dry, and hang them again,” Gazzo says.

Machine Wash

If you have fabric curtains, Gazzo says they can usually be washed in cold water on a delicate cycle. “If they are blackout shades, do not put them in the dryer—air dry preferably,” Gazzo recommends. Mock agrees, adding that you should also remove hooks and rings before washing the curtains on a gentle cycle.

Handwash

If your curtains have some sort of intricate embroidery, or you just don’t want to risk machine washing, Mock suggests handwashing them. “Fill a basin or bathtub with warm water and detergent and let the curtains soak for a while before rinsing and hanging up to dry,” she recommends.

Dry Clean

If the instructions recommend it—dry clean your curtains. In many cases, you can still get way with hand washing or machine washing these items on a delicate cycle, but if you’re especially worried about ruining your curtains, then it’s better to be safe than sorry.

What About Plastic Curtains?

If you have plastic curtains (like shower curtain liners). Gazzo says you can also clean them by hand. “Plastic curtains are easier in a way because you can just soak them in your bathtub or a large plastic bowl with water and 1-2 cups of vinegar, and scrub them with a cleaning brush,” he says. And, he notes that plastic curtains are more resistant to more abrasive cleaning products, like bleach.

In addition, Gazzo notes that plastic curtains are usually washing machine safe—unless the instructions indicate otherwise. “If you’re going to use your washing machine, put a few towels in with them to create friction and scrub the dirt off,” he advises.
