Understanding and Preventing Blue Stains on Pillow After Sleeping

A bunch of strange blue stains on a pillow after sleeping is a confusing sight to wake up to. After all, a night’s rest should only bring feelings of refreshment rather than disappointment. So, what can cause such types of stains?

In this article, we delve into the root causes of such an issue. We also explore how bedding materials, some products, and even medical conditions can contribute to these awful marks.

Keep reading to find out why these stains occur, and explore all the practical solutions to prevent them.

Causes of Blue Stains on Pillows

Let’s take a moment to understand the factors that might lead to the appearance of those mysterious blue stains on your pillow. These factors can include the materials your pillow is made of and the products you use in your daily routine.

Understanding and Preventing Blue Stains on Pillow After Sleeping

Here are a few potential culprits for such stains.

1. Bedding Materials and Dyes

The kind of fabric your pillowcase is made of and the dyes used to make it can be huge reasons for those puzzling blue stains.

These colors can sometimes mix with the oils and sweat from your body. As a result, this can cause marks to appear on your pillowcases and bed sheets. Such marks have distinct colors, ranging from yellow to brown and purple, making things even more confusing.

That’s why you need to pay attention when you pick out pillowcases. It’s always a great idea to go for ones that don’t easily get stained or ones with colors that don’t transfer easily. If you choose darker pillowcases, they can also help in hiding any marks that might show up.

In all cases, knowing how bedding materials and colors are connected is useful. It helps you understand why some strange marks show up. Moreover, it also gives you ideas on how to keep them away.

2. Hair and Skin Products

The products you use on your hair and skin can also be sneaky sources of those blue or purple stains on your pillow. Hair products like gels, dyes, and creams might look fine on your head, but they can sometimes leave traces of color on your white pillow.

It’s not just hair products – your facial products can join the party too. Mostly, if you use creams, lotions, or oils on your face before bed, they can mix with the oils from your hair. This mixture can sometimes lead to colors bleeding onto your pillow.

That’s not all. If you’re used to wearing a hair bonnet or a sleeping mask, such accessories can also absorb these products and transfer their colors to your pillowcase.

To avoid such occurrences, you might want to think about using your facial products a bit earlier in the evening. This way, they have more time to settle into your skin before you hit the pillow.

Moreover, if you use a hair bonnet or a sleeping mask, you can consider choosing ones that won’t easily soak up and transfer colors.

3. Sweat, Body Oils, and Chromhidrosis

It can be surprising to learn how bodily fluids might team up with certain medical conditions to make those blue stains even more mysterious. Night sweats may mix with the dyes in your pillowcase, leading to some unexpected colored marks.

That said, there’s another layer to this mystery – medical conditions. One rare condition called “chromhidrosis” can make your sweat contain colors. When this colored sweat mixes with your pillowcase, it can create stains that seem to appear out of nowhere.

If you’re experiencing night sweats or suspect you might have a medical condition like chromhidrosis, it’s a good idea to talk to a doctor. They can help you understand what’s going on and guide you through many sleeping issues.

Preventing Blue Stains on Pillows

Now that we’ve uncovered the reasons behind those tricky blue stains, it’s time to focus on what you can do to prevent them. Luckily, by following some simple steps, you can significantly reduce the chances of finding those annoying blue stains.

Here are five practical ideas on how to keep your pillow looking fresh and stain-free.

1. Choosing the Right Pillowcase

Opting for pillowcases made from materials like bamboo, which naturally repel colors, can be a smart choice.

Additionally, you can explore pillowcases specifically designed to resist stains. These innovative materials are less likely to absorb colors, helping to keep your pillow free from unwanted marks.

2. Regular Laundering

Just like your clothes, your pillowcase needs regular cleaning too. Washing it in cold water can help remove sweat, body oils, and any product residues that might cause staining.

Using a regular laundry detergent is fine, but you might also consider a liquid detergent designed for sensitive skin. In all cases, be sure to follow the care instructions on the pillowcase to maintain its quality after washing.

3. Color Consideration

If you’re still concerned about stains, choosing darker-colored pillowcases can be a practical solution. Dark colors are less likely to show marks, giving you peace of mind even if some residue gets on your pillow.

Alternatively, you might opt for pillowcases with patterns that can help camouflage any minor stains.

4. Pre-Sleep Routine

Paying attention to your pre-sleep routine can also make a significant difference. If you use hair or skincare products before bed, give them time to dry before resting your head on the pillow. This way, they’re less likely to transfer color.

Similarly, if you use a hair bonnet or a sleeping mask, make sure they’re clean and colorfast to prevent color transfer.

5. Pillowcase Exchange

To ensure your pillow remains fresh and stain-free, consider rotating your pillowcases regularly. Furthermore, having a spare set of pillowcases allows you to switch them out for washing while maintaining a clean sleeping environment.

Cleaning Blue Stains From Pillows

Even with all the preventive measures in place, the occasional stain might still find its way onto your pillowcase. That said, there’s nothing to worry about, as dealing with such stains doesn’t have to be a hassle.

Follow these steps to effectively clean and remove any stains appearing on your pillowcases overnight.

Step #1: Act Swiftly

As soon as you notice a stain on your pillowcase, it’s essential to take action promptly. That’s because stains are often easier to remove when they’re fresh and haven’t had time to set into the fabric.

The longer a stain lingers, the more it can bond with the fibers of the pillowcase, making it tougher to eliminate.

Step #2: Apply Gentle Blotting

Once you notice the stain, gently blot the affected area with a clean cloth or a paper towel. The goal is to absorb as much of the stain as possible without rubbing it.

If you rub a fresh stain, it can cause it to spread and become more embedded in the fabric.

Step #3: Flush With Cold Water

After blotting the stain, flush the area with cold water. This step helps to dilute and loosen the stain from the fabric. Cleaning experts also recommend flushing the stain from the back of the pillowcase to push it outwards rather than further into the fabric.

Step #4: Use a Mild Detergent

For tough stains, fix a quick mild liquid solution with cold water. Apply this mixture to the stained area and gently rub the fabric together to work in the detergent.

Although it may help remove stubborn stains, you should avoid excessive use of detergent. That’s because too many chemicals may ruin the pillowcase fabric.

As an alternative to detergents, you can sprinkle some baking soda on the stain and spray it with white vinegar.

Step #5: Try the Soaking Method

If the ugly stains persist, submerge the affected area of the pillowcase in cold water with a few drops of mild detergent. Allow it to soak for 15 to 30 minutes before hitting the washing machines. Then, gently rub the fabric together to help dislodge the stain.

What To Consider When Cleaning Pillows

Learning how to effectively clean stains can extend the life of your pillowcases. However, before following the previous steps, make sure to keep the following tips in mind.

  • Avoid using hot water, as it can make the stain cling to the fabric and become harder to remove.
  • Air dry the pillowcase after cleaning, and don’t use heat, as high temperatures can set the stain further.
  • Hanging the pillowcase outdoors in sunlight can naturally lighten any remaining discoloration.
  • Make sure not to leave the pillowcases in direct sunlight for too long, as it may cause some colors to fade.
  • Exercise caution with using bleach, especially on pillowcases with patterns or colors.
  • Check the care label before using any kind of cleaner to ensure it’s safe for the fabric.
  • Before using any stain-removal method, test it in a hidden area of the pillowcase to avoid unintended damage.


Now you know what causes blue stains on a pillow after sleeping. It’s not just a type of dye transferred from your wet hair or clothing. It can also be a result of a rare medical condition.

Picking suitable pillowcases, cleaning them regularly, and being careful with your hair products can be great solutions for this issue. Having said that, if stains do happen, remember to act fast, use cold water, and go easy on the soap.

Although discovering stains on your pillow can be annoying, cleaning them shouldn’t be bothersome. Easy does it!
