Why Is My Mattress Turning Brown?

If you’ve noticed that your mattress is turning brown, this discoloration is typically due to a combination of moisture, sweat, body oils, and dust accumulation over time. However, there can be other contributing factors that also lead to a mattress turning brown, such as spills, the presence of bed bugs or dust mites, or even rust developing from the internal springs. It is important to address the cause of discoloration to maintain the hygiene and lifespan of your mattress.

Understanding Mattress Discoloration

Moisture and Sweat

The human body naturally loses moisture each night during sleep, even more so if you live in a warmer climate or have a tendency to sweat during the night. Over time, this moisture can seep into your mattress, leading to mildew or mold growth, which can cause the mattress fabric to stain and turn brown. It is crucial to protect your mattress from excessive moisture by using a mattress protector and ensuring that your bedroom is well-ventilated.

Body Oils and Skin Cells

As we sleep, our bodies are constantly shedding skin cells and producing oils. When these oils and cells accumulate on the mattress surface, not only do they attract dust mites, but they can also contribute to a yellowish-brown discoloration. Routinely washing your bed sheets and employing mattress covers can help minimize this build-up.

Dust and Dirt Accumulation

Over time, dust, pollen, and other particulates from the air can settle on your mattress, embedding themselves into the fabric. While this may not be immediately noticeable, this accumulation can lead to a dull, brownish hue on the mattress surface. Regular vacuuming of the mattress can reduce this type of dirt buildup.

Spills and Stains

Unprotected mattresses are vulnerable to spills, which can result in stains. Spilled beverages like coffee or tea, accidentally dropped food, or pets’ messes can seep into the mattress fibers, leaving behind brown stains that are often tough to remove once they’ve set in.

Pest Infestation

Bed bugs and dust mites can cause small brown spots to appear on your mattress due to their fecal matter or crushed bodies when squashed unknowingly during sleep. An infestation not only discolours your mattress but also poses a potential health risk, making it essential to inspect regularly and treat any signs of pests promptly.

Rust From Springs

In innerspring or hybrid mattresses, if there’s enough moisture, the metal springs inside can begin to rust. This rust can seep through to the outer layers of the mattress, causing brownish-red stains. While it might be difficult to prevent the internal components from moisture completely, using a dehumidifier in the room may help.

Mattress Cleaning and Maintenance

Using Mattress Protectors

A straightforward and effective way to shield your mattress from many of the issues that cause brown staining is by investing in a quality mattress protector. These protectors sit atop the mattress and beneath your sheets, providing a barrier against moisture, oils, and dirt.

Vacuuming and Deodorizing

Regularly vacuuming your mattress can help eliminate dust and other particulates before they penetrate deeper layers. Additionally, sprinkling baking soda over the surface of your mattress, leaving it for several hours, and then vacuuming it up can help to neutralize odors and lift light stains.

Spot Cleaning Stains

When you encounter a spill or notice a spot on your mattress, it’s best to address it immediately with a mild detergent and cold water. Gently dabbing (not rubbing) the area can prevent the stain from spreading or setting in. Ensure the mattress is completely dry before remaking the bed to avoid moisture-related issues.

Professional Cleaning

For stubborn stains or widespread discoloration, a professional mattress cleaning may be the most effective solution. Cleaning professionals have the tools and expertise to deep clean your mattress without leaving it overly wet, which could cause further problems.

When to Replace Your Mattress

Signs of Major Wear and Tear

Mattresses typically have a lifespan of 7 to 10 years, but this can vary depending on the quality of the mattress and how well it’s cared for. If your mattress shows significant signs of wear, such as large brown stains that cannot be cleaned or persistent odors, it might be time to consider a replacement.

Comfort and Support Issues

Aside from visual signs of wear, if your mattress no longer provides adequate support or comfort, leading to poor sleep or body aches, this is a strong indication that it’s time to invest in a new mattress.

Hygiene Considerations

Once a mattress is heavily stained or has been home to pests like bed bugs, it might be more hygienic to replace it rather than attempting extensive cleaning, especially if the mattress is already near the end of its recommended lifespan.

Finishing Thoughts

A brown mattress can be the result of many factors, with moisture and sweat, the buildup of body oils and skin cells, and dust accumulation being the main contributors. Preventative measures like using a mattress protector, regular cleaning, and maintaining a dry environment are key to keeping your mattress in good condition. However, if your mattress is showing significant signs of wear, persistent stains, or loss of support, it may be time to consider a replacement for the sake of your sleeping comfort and overall health. Remember, a clean and well-maintained mattress is crucial for a good night’s rest.
