The 6 Dirtiest Spots in Your Bedroom You’re Probably Ignoring

When it comes to household chores, the bedroom often feels like the easy zone. All you have to do is tidy up the nightstands, change the sheets, run the vacuum, and you’re good to go, right? Well, not quite. While your bedroom might appear fairly clean (aside from maybe some clothes littering a chair or bench), there’s a good chance it’s harboring hidden dirt, dust, and germs in places you rarely think to check.

Fortunately, once you know where those sneaky spots are hiding—and how to clean them properly—keeping your bedroom clean is easier than you think. Keep reading to discover the dirtiest places in your bedroom that you’ve probably been overlooking.

We spoke with Mary Gagliardi, also known as Dr. Laundry, and Clorox’s in-house scientist and cleaning expert, to find out which areas in your room get the grimiest. According to her, “Bedrooms are private spaces in the home, making it easy to ignore (just close the door) and postpone cleaning thoroughly on a regular basis.” Examples of these neglected spaces or items include hampers, baseboards, and light fixtures (to name a few).

1. Light Switches

Think about how often you touch your bedroom light on and off each day. Now think about how often you actually clean those switch plates. If you can’t remember the last time, you’re not alone. “Because bedrooms are so familiar, people don’t always look at a light switch when they enter the room,” Gagliardi explains. “Oils from hands transfer to the switch plate, and grime builds up without being noticed.”

Light switches are considered high-touch surfaces, meaning they’re places for germs to spread easily, especially when multiple people share the same room. The fix is quick and straightforward: wipe them down once a week with disinfecting wipes or a cloth dampened with a cleaner to remove oils, fingerprints, and bacteria; do this more frequently if you or your partner is sick. It’s a task that takes less than a minute but makes a big difference in keeping your space clean and healthy. As Gagliardi reminds us, “It really just takes awareness to make it part of your cleaning routine.”

2. Laundry Hampers

Your laundry basket might be holding more than dirty clothes. “These pick up dirt and dust when dirty laundry gets tossed in,” says Gagliardi. If you habitually toss sweaty items like your workout clothes, mildew could form as well.“The laundry may be removed for washing, but the basket or the fabric liner in the hamper can easily be ignored, especially when doing the laundry takes up enough time as it is.” 

Wipe down hampers with a plastic base monthly with a disinfectant to keep them sanitized. For removable cloth liners, toss them in the washing machine once a month on the warmest setting allowed on the care label. To go the extra mile, Gagliardi recommends adding a laundry sanitizer to your machine’s fabric softener compartment to kill germs that may have transferred from the dirty laundry.

3. Baseboards and Under Furniture

The space underneath and around your bed can quickly become a catch-all for dust, lint, and pet hair. The same goes for baseboards, especially those hidden behind furniture. “Even if you have a bed skirt, dust bunnies and dirt will still accumulate,” says Gagliardi. “This can also be a problem under dressers with low clearance between the underside of the dresser and the floor.”

To tackle the problem, vacuum under the bed with your upholstery attachment, and then use an extendable duster or a microfiber cloth to wipe down the baseboards. Doing this at least quarterly can help keep allergens at bay. If someone in the room has allergies, aim to dust more frequently.

4. Mattresses

Even if you’re regularly washing and changing your bedding, your mattress doesn’t always garner the same kind of attention. “Mattresses are generally out of sight, out of mind, making cleaning them easy to put off until later,” Gagliardi says. “Cleaning and rotating helps them last longer, so it’s worth making this part of your cleaning routine.”

Routine maintenance starts with vacuuming the entire surface using your vacuum’s upholstery attachment. Use the crevice tool to reach seams, trim, and stitching where dust and dead skin can accumulate. To remove protein-based stains, including blood, Gagliardi suggests applying a product such as Clorox Urine Remover directly to the affected area, letting it sit for 3 minutes, then blotting with a damp cloth.

Another way to keep your mattress in tip-top shape is to rotate it every three months, which prevents uneven wear and tear. “This is also the perfect time to remove and wash the mattress pad using hot water, your favorite detergent, and bleach,” says Gagliardi.

5. Decorative Pillows and Duvet Covers

You may take pride in creating a hotel-inspired bed every morning, complete with perfectly arranged throw pillows and a cozy duvet cover, but just below that aesthetic appeal lies a layer of dust. “These [things] aren’t exactly hidden, but they aren’t always cleaned regularly either, which means they can accumulate dust,” Gagliardi explains.

Her advice? Vacuum decorative pillows using your vacuum’s upholstery attachment to remove surface dust. Wash pillow shams and duvet covers monthly following the care label instructions. This not only keeps the bedding fresh but also helps maintain color uniformity between matching pieces, which can fade unevenly if washed separately.

6. Bed Skirts

If you’ve ever tried removing a bed skirt, you know it’s a bit of a hassle. That’s probably why so many people skip cleaning it altogether, but according to Gagliardi, it’s worth the effort. “Bed skirts do get dirty, especially for pet owners with dogs or cats that like to rub up against them,” she says. Dust, pet hair, and dander can all cling to the fabric, making it a hidden hotspot for allergens.

To clean, she suggests pretreating stains before machine-washing the skirt in warm water. Instead of tumble drying, iron out any wrinkles and hang it to air-dry completely. Gagliardi recommends washing your bed skirt every 3 months, so feel free to habit-stack this task with rotating your mattress.
