Easy To Follow Guide On How to Deodorise a Mattress

While we sleep, our bodies transfer dead skin cells, sweat, and other physiological oils to our mattresses that form dust and feed dust mites or result in a strange, musty smell that gets on your nerves. Presuming it’s an unpleasant nuisance, we prepared helpful tips on how to deodorise a mattress and keep it fresh for many nights.

Deodorising a Mattress: Tips & Tricks

Let’s take a look at some affordable, DIY solutions to the problem of mattress smell.

Deodorise Your Mattress With Water & Vinegar

According to Popular Science, acetic acid molecules neutralize malodorous, volatile compounds by bonding with them. This means that when vinegar evaporates into the air, it takes these molecules along and neutralizes the smell, completely getting rid of the scent. 

  • To create a natural deodoriser, you should mix equal portions of distilled white vinegar with water in a spray bottle.
  • Gently spray the mixture over the whole mattress, but make sure not to moisten it too much. Then, try tipping the mattress up on its side to spray the mixture on the back side of it too. 
  • Once it is completely dry, gently lay the mattress on your bed base to prepare it for the next step. 

Baking Soda

Baking soda works wonders when it comes to neutralising odours and absorbing moisture. Apart from using it as a leavening agent in baked goods, you can also apply this multifunctional alkaline compound to your mattress.

  • Gently sprinkle baking soda over your mattress’s surface, and leave it to sit overnight or during the whole day.
  • Once twelve to twenty-four hours have passed, vacuum the mattress using the upholstery attachment of your vacuum cleaner to remove the baking soda and dust. 


When it comes to absorbing bodily fluids, liquids, and odours, cornstarch works like a charm. Couple that with its lack of scent, and you’ve got yourself a crème de la crème organic deodorant. 

  • To further freshen your entire mattress, you can add cornstarch to your baking soda layer and let the mixture stay for up to twenty-four hours. 
  • Try opening a window to let the fresh air inside, helping your mattress to dislodge any lingering odors. 

Essential Oils

Using essential oils can help with better relaxation before bedtime. 

  • Add a few drops of your favorite essential oil to the baking soda and cornstarch mixture to promote better relaxation. We suggest using peppermint oil as it’s not only an organic deodorizer but has an additional antimicrobial property
  • Make sure not to use too much oil, as this might come at the cost of making a mess on your mattress that you’ll have to deal with.

Prevent Future Odours

It’s not just about fixing the problem - it’s also about making sure it doesn’t happen again. Let’s take a look at how you can protect your mattress from absorbing scents.

Use a Mattress Cover or Protector

A new mattress protector or cover is always an excellent investment as it will keep your mattress in good shape for a longer period.

Regularly Clean Your Box Spring or Mattress Foundation

As with everything else in our homes, box springs, mattress foundations, or other bed bases may quickly amass dust particles and transmit them on our mattresses. At some point, this may cause your mattress to emanate a musty, foul smell.

  • To prevent this, regularly remove the mattress to vacuum your box spring or mattress foundations on all sides, ensuring there isn’t any dust left. 

Promote Air Circulation

The most sure-fire way to a fresh-smelling mattress is to promote constant airflow in your bedroom and within the mattress itself.

  • You may use a slatted base for your bed frame to enable air circulation inside your mattress as they offer an excellent level of ventilation. This will allow your mattress to better wick away moisture and prevent mold growth before it’s ever a problem.

Final Takeaway

Those musty odours are an actual nuisance and can even remind you when it is time to buy a new mattress. To get rid of these smells once and for all, we recommend combining all the solutions mentioned above, as choosing only one might do the trick, but it may not give you the long-lasting results you desire.

In addition to all the steps for deodorizing a mattress, you now also know how to prevent future inconveniences, which will save you from constantly repeating them. In a nutshell, find your perfect mattress pad or cover, allow air to enter your bedroom regularly, and clean your mattress from time to time.
