Ever noticed those mysterious black spots showing up on your pillowcase? Yikes! Nothing ruins a relaxing bedtime vibe faster than spotting these on your favorite pillows.

I totally get it - it's gross and a bit concerning.

But don’t worry, most of the time, these black spots are harmless, but they could also be a sign of something that needs your attention.

In this post, I’ll go over what those black spots on pillowcases are and how to get rid of them.

What Causes Black Spots On Pillows?

There are a few different reasons this could happen. While some causes are harmless, others can point to an underlying issue. Let’s go over the main reasons:

#1 Mold

The most common reason behind the black spots on your pillows is mold.

Mold thrives in warm, moist environments—exactly like the conditions you might have on your pillow.

Every night, your pillowcase absorbs moisture from your skin, sweat, and hair. If the pillowcase stays damp for too long, like after a hot night’s sleep or if you’ve spilled something on it, mold can start growing. These black spots are often the result.

Mold can sometimes be tricky to notice, but if you start smelling something musty or see discolored patches, it’s likely mold.

#2 Dust Mites

Dust mites—those tiny, almost invisible creatures—are another cause of black spots.

They live in warm, damp areas like your bed, feeding on dead skin cells and the oils your body produces. Over time, their presence can lead to dark stains on your pillowcase.

Even worse, their feces can leave behind dark spots as well.

While you can’t exactly see the dust mites themselves, their waste can show up as tiny, dark specks. It sounds gross, but honestly, it’s something most of us deal with.

Dust mites thrive in beds and pillows because they love warmth and moisture. If you’re allergic to dust mites, you might also notice sneezing, a runny nose, or itchy eyes when you wake up.

#3 Scalp Oils And Product Buildup

If you’ve been using a lot of hair products like gels, hairsprays, or oils, those could be the reason you’re seeing black spots in your pillowcase.

When you lay your head on your pillow, these products transfer from your hair to your pillowcase. Over time, the buildup of these oils and products can turn into dark, sometimes black, spots on the fabric.

Plus, it can attract dust, dirt, and even oils from your skin, making the spots even worse.

It’s easy to avoid this. Just make sure you’re not overloading your hair with products, and try to give your scalp a good wash regularly to clear away buildup.

If you have oily hair, it might help to use a towel or something to protect your pillowcase.

#4 Bed Bugs

Yes, bed bugs. While they’re not the most common cause of black spots in pillows, they can leave dark stains behind.

Bed bugs themselves are usually reddish or brownish, but their feces can show up as black dots on your pillowcase. They usually leave spots in clusters or lines, not randomly across the pillow.

If you see these black specks, it could mean you have an infestation.

Along with the black spots, you might also notice small blood spots, as bed bugs feed on human blood while you sleep. You might even have itchy red marks on your skin.

#5 Fabric Deterioration

Sometimes, black spots aren’t from anything gross—they might simply be from the fabric wearing down.

Over time, pillowcases can deteriorate from constant washing, friction, and exposure to body oils. This wear and tear can lead to small holes or tears in the fabric, where dirt and oils collect and eventually turn into black spots.

It’s the fabric breaking down, not something “gross” causing the issue.

If your pillowcase is old or has seen a lot of use, this could be the culprit.

If you notice this happening, it might be time to replace your pillowcase. When fabric starts to deteriorate, it can get weaker, and you don’t want it to tear completely. Plus, fresh pillowcases just feel nicer.

How To Remove Black Spots On Pillowcase

Okay, now that you know what could be causing those black stains in your pillowcase, let’s talk about how to get rid of them. Most of the time, it’s not a huge deal. A good cleaning can usually solve the problem. Here’s how to do it:

Wash In Hot Water

First thing’s first: Wash your pillowcase in hot water.

This can help kill any germs, mold, or dust mites hiding in the fabric. Hot water is also great at removing oils and dirt that might have built up on the fabric.

If you’re worried about color fading, test a small section first, but generally, hot water is safe for most pillowcases.

Use White Vinegar Or Baking Soda

If hot water alone doesn’t do the trick, add some white vinegar or baking soda to the wash. Both of these are excellent at breaking down stains and odors.

Plus, they're cheap and eco-friendly. Win-win!

For vinegar: Add 1 cup to your wash cycle along with regular detergent. The acidic nature helps break down buildup and kill bacteria. Don't worry about the smell - it disappears when dry!

For baking soda: Sprinkle directly on wet spots before washing, or add 1/2 cup to your wash. It's great for neutralizing odors and lifting stains.

Try Hydrogen Peroxide

If the spots are still there after washing, hydrogen peroxide is your next best bet.

Apply it directly to the spots, let it sit for about 10 minutes, then wash it out.

Hydrogen peroxide is great for removing stains, especially mold and mildew stains. Just be sure to test it on a small area first to make sure it doesn’t bleach your fabric.

Replace The Pillowcase If It’s Mold

If you find that the black spots on your pillowcase is mold and no amount of cleaning can get rid of them, it might be time to say goodbye to your pillowcase.

Mold can sometimes be impossible to fully remove, and you don’t want to risk breathing in those spores.

New pillowcases aren't super expensive and are definitely cheaper than potential health issues from sleeping on moldy bedding. Think of it as an opportunity to refresh your bedroom look!

Bottom Line

Black spots on your pillowcase can be caused by a number of things: mold, dust mites, hair products, bed bugs, or just fabric breakdown.

It’s annoying, but most of the time, it’s not a huge problem.

A quick wash with hot water and some vinegar or baking soda usually does the trick. If the spots persist or seem like they’re from mold, though, replacing the pillowcase might be the best option.
