Why Does Your Mattress Smell Over Time? Causes & Solutions

There’s nothing more satisfying than slipping into a fresh, clean bed at the end of a long day, is there? Now, imagine this: drained and tired, you fall into your bed only to be met with a foul, strange smell.

Mood? Instantly ruined. And sleep? Suddenly, it feels like a chore. Even the highest-quality mattresses can develop odors over time if not maintained proactively. But why does this happen, and what can you do about it? Read on. Ahead, we will tell you everything you need to know.

Common Causes of Mattress Odors

Here are some of the most common reasons why your mattress smells bad.

Sweat and Body Oils

Your body releases sweat and oil in your sleep. Even with bedsheets, they seep into your mattress. If you don't clean your mattress periodically, it creates a musty, stale odor. You can use mattress protectors to curb the buildup.

Dust and Dead Skin Cells

Did you know? On average, a human sheds about 30,000 to 40,000 dead skin cells per hour, which adds up to roughly 0.5 to 1 gram per day. So, even when you sleep, you shed skin cells. They keep accumulating along with dust. This combination not only attracts dust mites but also contributes to an unpleasant smell. Hence, regularly vacuuming your mattress is a must.

Spills and Food Residues

Sometimes, there's no greater comfort than watching a movie and enjoying some munchies on your bed. However, accidental spills can penetrate deep into your mattress foam and fabric. When left untreated, the residues might ferment and lead to a sour smell. That's why prompt cleaning is a must.

Pet Odors

If you are a pet parent, you probably love cuddling your furry baby and sleeping with them. However, pet hair, dander, and even occasional accidents can leave a lingering foul smell in your mattress. So, make sure you use a waterproof mattress protector and clean your bed regularly.

Humidity and Mold/Mildew

Whether you live in a hot and humid climate or your bedroom has poor ventilation, it causes moisture to seep into your mattress. This creates a perfect habitat for mold and mildew to grow. Here, you may experience a strong musty odor. Dehumidifiers, proper airing, and mattress rotation are what you need.

Smoking and Strong Scents

If you are a smoker or use extremely strong perfume, it can penetrate the mattress fabric and leave a long-lasting odor. Infact, the smell of cigarettes is such that even after you air out your mattress, a persistent smell remains.

New Mattress Off-Gassing

Some new mattresses, like memory foam or synthetic, may emit a chemical-like odor. The off-gassing is because of volatile organic compounds (VOCs). It usually fades after a few days, but airing or natural ventilation is important.

How to Identify the Source of the Smell

The best way to begin the odor elimination process is to first identify the cause.

• Start by removing all bedding. See the surface for visible stains, spills, or damp spots. If you find any, it can be one of the reasons.
• Next, pay attention to the seams and corners. This is where food crumbs, sweat, or even pet accidents often linger but go unnoticed.
• Now, a musty smell usually means moisture or mold. Sour or pungent odors generally mean sweat, body oils, or food residues.
• If there's a sharp chemical scent, it may be off-gassing.
• Once you assess and do a thorough inspection, the reason becomes quite evident.

Quick Fixes for Mild Mattress Odors

The tips below are not only quick fixes, but doing some of them regularly can help keep your mattress smelling fresh and clean.

• Vacuuming

  One of the easiest ways to keep your mattress clean is to vacuum regularly. This tackles mild odors and removes pet dander, dust, and other allergens. However, you must make sure you use an upholstery attachment. Clean the surface, seams, and corners diligently. Also, make it a weekly practice.

• Vinegar Treatment

  Ingredients from your kitchen can be a lifesaver when nasty odors take over. We are talking about white vinegar. Yup, it is a natural deodorizer that can neutralize smells. For this trick, take a spray bottle and fill it with a diluted vinegar solution. Now, lightly mist the solution over the mattress surface and allow it to air dry completely. Don't worry, the smell of vinegar fades as it dries, and it also eliminates other stubborn odors along with it.

• Baking Soda Treatment

  Another gem from your kitchen is baking soda. Again, it's a deodorizer and can eliminate strong odors as well. Sprinkle a generous layer over the mattress surface and let it sit for several hours. Then, vacuum thoroughly. Why does this work? Baking soda absorbs odors from sweat, food, or pets. So, once you are done, your mattress will smell fresh and clean again.

• Sun Exposure

  Lastly, exposing your mattress to direct sunlight can do wonders as it eliminates moisture, kills bacteria, and mold spores. It also gets rid of musty smells and gives your mattress a quick refresher. For this, you can place your mattress near the windows or place it on a clean surface outdoors.

Deep Cleaning for Persistent Smells

Now, let’s get down to it. Sometimes, deep cleaning is the only way to truly eliminate stubborn odors. The good news? These methods can also be used periodically as part of your regular mattress maintenance.

Spot Cleaning

This is only for small stains or localized spots. Here's how you can do it:

• Use a mild detergent. If necessary, you can also mix it with some water or fabric-safe cleaner.
• Dab the stain gently with a clean cloth dipped in the solution. Remember, don't scrub or use too much force as it can damage mattress fibres.
• Then, use another clean dry cloth or tissues to blot the area.
• Let it air dry completely.

Steam Cleaning

Steam cleaning is excellent as it seeps deep into the mattress layers. It kills bacteria, dust mites, and mold spores. For this,

• Use a handheld steam cleaner.
• Apply only short bursts of steam across the surface. Be careful not to soak it.
• Allow the mattress to dry thoroughly afterwards. It's best to open the windows and ensure good ventilation.

Enzyme Cleaners

Enzyme cleaners are used to get rid of odor caused by organic matter, such as sweat, urine, or pet accidents. What these cleaners do is break down the organic compounds at a molecular level and completely get rid of any stains and smells. However, before using them, always do a small spot test to ensure compatibility with your mattress material.

• Spray the enzyme cleaning solution directly on the affected area.
• Let it sit for 10-15 minutes or as per the instructions given.
• Then, using a clean cloth or tissues, blot it well.
• Let it air dry completely.

Note:Always check your mattress care instructions before using any cleaning method. Make sure the material is compatible with the ingredients and techniques to avoid damage.

Prevention Tips to Keep Your Mattress Fresh

Is there a way to prevent your mattress from smelling bad? Yes! Take a look.

Use a Waterproof Mattress Protector

Your mattress needs a waterproof mattress protector. It is the first line of defense against spills, sweat, and accidental messes. And, washing a mattress protector is much easier than cleaning your mattress. For instance, a bamboo mattress protector by The Sleep Company is plush, offers dual-layer defence, is stain-resistant, and oh-so-soft and breathable. So, using protectors like these elevates your comfort and can be convenient in the long run.

Regular Rotation

This is the easiest tip ever! Simply rotate your mattress every three to six months. It helps distribute wear evenly and prevents certain areas from becoming odor-prone due to constant pressure and body contact. Infact, doing this also reduces sagging and maintains your mattress's structure.

Change Bedding Regularly

This one is a no-brainer. Change your bedding regularly. Make it a weekly routine or even more often if needed. Remember, your sheets, pillowcases, duvet covers, blankets, etc., collect sweat, body oils, and dead skin cells much faster than you might think. So, if you don't change it frequently, the residue will seep deeper into your mattress. And of course, over time, it leads to a nasty odor. You can also use hot water to wash your bedding to eliminate bacteria.

Air It Out Monthly

Airing out your mattress under direct sunlight can be great. If that's not possible, place it near the windows and switch on the fan. Fresh air and UV rays kill odor-causing bacteria, reduce humidity, and make your mattress feel fresher.

No Food in Bed Rule

We know it is tough. But if you are someone whose mattress frequently sees food accidents, then it's time to enforce the no-food-on-bed rule. It not only prevents messes but also ensures your mattress remains cleaner and odor-free in the long run.

Cleaning Your Mattress Every 6 Months

Opt for deep cleaning your mattress every six months. This is what you must do:

• Start by removing all the bedding and giving them a hot water wash.
• Next, vacuum your mattress thoroughly.
• If there are stains, spot clean them.
• Use the baking soda or steam method to refresh the surface of your mattress.
• After a few hours, vacuum again and air dry your mattress in the sunlight.

When It’s Time to Replace Your Mattress

Have you been cleaning your mattress to no avail? Well, maybe it's time for a replacement. Mattresses naturally wear out over time. This is mainly because they absorb sweat, spills, body oil, and allergens. Some of them are so stubborn that removing them becomes almost impossible. As per the general rule of thumb, most mattresses last between 7 and 10 years. However, bad odors, sagging, and discomfort are a few signs that your mattress has reached the end of its life. If that's the case, investing in a new mattress is what you need.
