A good night’s sleep is a precious commodity, but it can be easily disrupted by an unpleasant and persistent problem: the dreaded sweat smell on your mattress. Whether it’s the result of a hot summer night, an intense workout before bedtime, or simply the natural process of our bodies releasing moisture during sleep, a sweaty mattress can be a source of discomfort and embarrassment.

The stench can linger and affect the overall hygiene of your sleep environment, leading to restless nights and potential health concerns. Fortunately, there are effective ways to banish that unpleasant odor and ensure your mattress remains fresh and inviting.

How to Remove Sweat Smell from Mattress

In this comprehensive guide, we will explore various techniques and remedies on how to remove sweat smell from mattress, helping you regain the serenity and comfort you deserve for a restful night’s sleep. Say goodbye to those stubborn odors and hello to a revitalized sleeping experience.

Why Sewat Smell Is Coming from the Mattress?

Sweat stains on mattresses are most likely caused by sweat that has been absorbed through the mattress fabric. Sweat is a natural body secretion and, when left unchecked, can cause an unpleasant odor to linger in your mattress.

Sweat is made up of salt, proteins and oils which further contribute to the problem of smelly mattresses. The composition of sweat also makes it difficult to remove, as the sweat has a tendency to sink deep into mattress fibers.

Fortunately, there are ways that you can tackle this problem and help get rid of the sweat smell from your mattress. The first step is to strip your bedding and mattress covers off and wash them separately on hot water cycle with a biodegradable detergent in order to remove any embedded sweat residue. After the covers have been washed, it is important to dry them thoroughly in order to prevent the smell from returning.

Once your bedding has been cleaned, you can focus on cleaning the mattress itself. Vacuuming is an effective way of getting rid of surface dirt and dust from your mattress, as well as possible sweat stains. Any stubborn stains should be treated with a stain remover before being allowed to dry. Alternatively, you can sprinkle baking soda on the entire mattress and let it sit overnight; this will help absorb any odors.

Importance of Maintaining a Fresh-Smelling Mattress

Maintaining a fresh-smelling mattress is very important for many reasons. Not only does it create a more pleasant sleeping environment, but it also helps with personal hygiene and overall health. Dust mites and other allergens can easily accumulate in the fabric of mattresses, leading to allergies or asthma attacks.

In addition, sweat and body oils on mattresses can create an ideal environment for bacteria and mold growth, which can be harmful to one’s health. Removing sweat smell from mattresses on a regular basis will help keep your mattress smelling fresh and free of dust mites, allergens, bacteria, and mold. With the right cleaning materials and methods, it is possible to remove sweat smell from mattresses quickly and easily.

10 Steps How to Remove Sweat Smell from Mattress

1. Vacuum the Mattress

The first step in removing sweat smell from a mattress is to vacuum it thoroughly. This will help to remove any dirt, dust, and debris that may be trapped in the mattress. It is important to use a vacuum with an upholstery attachment so that you can get into all of the nooks and crannies of the mattress. Additionally, make sure to go over the mattress multiple times for best results.

2. Sprinkle Baking Soda

Once you have vacuumed the mattress, sprinkle baking soda over it and let it sit for at least 30 minutes. The baking soda will help to absorb any odors that may be present in the mattress. After 30 minutes, use your vacuum again to remove any excess baking soda from the mattress.

3. Apply Vinegar

After vacuuming up the baking soda, apply white vinegar directly onto the affected areas of the mattress using a spray bottle or cloth. Let the vinegar sit on the mattress for at least 15 minutes before wiping it away with a damp cloth or sponge. The vinegar will help to neutralize any odors that may be present in the mattress and will also help to sanitize it as well.

4. Sprinkle Salt

Once you have applied vinegar to your mattress, sprinkle salt over it and let it sit for another 30 minutes before vacuuming up any excess salt that may remain on your bedding surface. The salt will help to absorb any remaining odors from your mattress as well as helping to keep new odors from forming in future uses of your bedding surface area.

Use a Vacuum With an Upholstery

5. Wash Bedding

Next, wash all of your bedding including sheets, blankets, pillows, and comforters in hot water using detergent and fabric softener if desired. Make sure not to overload your washing machine so that everything gets cleaned properly without leaving behind any residual smells or dirt particles on your bedding items after they are washed and dried out completely afterwards too!

6. Air Out Mattress

After washing all of your bedding items, take them outside or open some windows inside so that you can air out your entire bedroom space including mattresses too! Allow fresh air into all corners of this room until everything smells nice again before bringing back all freshly laundered items back inside again too!

7. Use Odor Eliminators

If you still find yourself struggling with getting rid of the sweat smell from your mattress then consider using odor eliminators such as sprays or powders specifically designed for this purpose too! These products are usually safe enough even if used around pets or children but always read instructions carefully beforehand just like anything else!

8. Use Charcoal Briquettes

Charcoal briquettes can be placed underneath mattresses to absorb moisture which helps reduce sweat smell significantly too! Place a few briquettes underneath each corner of mattresses before covering them with regular sheets again – this should help reduce odors quickly once done right!

9. Clean Mattress Regularly

Cleaning mattresses regularly is one way you can prevent sweat smell from occurring in future uses too! Vacuum them at least once every two weeks and spot clean stains when necessary – this should keep mattresses smelling fresh longer than usual without putting much effort into it either way!

10. Replace Mattress If Necessary

If none of these steps seem effective enough then consider replacing old mattresses altogether if possible – sometimes there’s just no other way one can get rid of the persistent sweat smell other than getting new ones entirely instead unfortunately…

Factors Leading to Sweat Odor on Mattresses

Sweat odor on mattresses is a common problem, and it can be caused by several factors. The most common causes of sweat odor in beds are poor hygiene, heat-trapping fabrics, trapped moisture, dust mites, and bacteria buildup.

Good hygiene habits are essential to prevent sweat odor on mattresses. Sweating is natural and happens to everyone, but it’s important to clean up after yourself. Make sure to wash your sheets regularly and use a mattress protector when sleeping, as this will help keep sweat from soaking into the mattress.

Heat-trapping fabrics like synthetic materials can also cause mattresses to smell bad due to trapped body heat and moisture. Consider using breathable fabrics like cotton or linen for bedding and mattresses. This will help to keep the mattress cool and reduce sweating.

Mattress protectors can also trap moisture and lead to sweat odor over time, so make sure to wash them regularly as well. Additionally, dust mites and bacteria buildup can cause bad odors in mattresses; use an anti-allergen spray to help keep your bed clean and free of odors.

Things to Consider When Removing Sewat Smell from Mattress

  • Check the Manufacturer’s Instructions. Before attempting to remove sweat odors from a mattress, make sure to check the manufacturer’s instructions for cleaning and care of the mattress. Some mattresses may require special cleaning procedures or products which could damage the mattress if not followed correctly.
  • Clean Regularly with Baking Soda. Baking soda is a natural odor absorber and can be used to keep sweat odors from forming on your mattress. Sprinkle baking soda across the top of your mattress, let it sit for 30 minutes or more then vacuum it off. Doing this regularly may help to reduce sweating smells over time.
  • Spot Clean with Laundry Detergent. If you have noticed a localized spot of sweat or odor, a laundry detergent like OxiClean can be effective for spot cleaning. Mix the detergent with water and use a sponge or cloth to scrub the affected area.
  • Use an Enzymatic Cleaner. Enzymatic cleaners are formulated to break down specific proteins, which is why they are often used to remove pet odors and stains.

Some Common Mistakes to Avoid When Removing Sweat Smell from Mattress

Spot Clean with Laundry Detergent
  1. Using too Much Soap or Detergent Solution: Many people make the mistake of using too much soap or detergent solution when attempting to clean a mattress that has been exposed to sweat. This can actually make the problem worse, as too much soap will leave behind a residue that won’t dissipate and further contribute to the smell.
  2. Not Using a Mattress Protector: Mattress protectors are designed to absorb sweat, preventing it from seeping into the mattress. Furthermore, they help prevent dust mites and other allergens from settling in the mattress, reducing the chance of any further odors developing.
  3. Not Changing your Sheets Regularly: Changing your bed sheets regularly can help keep sweat smells away and make sure you have a clean sleeping environment. It’s recommended that you change your bed sheets at least once a week, and preferably more often if possible.
  4. Not Using Baking Soda: Baking soda is one of the best natural odor removers out there, so it should definitely be used when attempting to get rid of sweat smells from mattresses. Sprinkle baking soda all over the mattress and let it sit for several hours. Then, vacuum it up with a powerful vacuum cleaner.
  5. Not Using an Air Purifier: Air purifiers are great at removing odors and allergens from the air, so placing one in your bedroom can help reduce sweat smells coming from the mattress.
Using a Deodorizing Spray


In conclusion, learning how to remove sweat smell from mattress is not as difficult as you may think. You can use baking soda, vacuum it up and even buy a mattress cover in order to prevent the smell from returning. All these steps will enable you to make sure that your mattress stays smelling fresh and clean for longer.

Furthermore, if all else fails, replacing the mattress or using a deodorizing spray might be your best bet when it comes to removing the sweat smell from your mattress permanently.
