How to get the smell out of the mattress?

Is there a foul smell emanating from your mattress? You’re not alone, so don’t worry. We slumber in our beds for around a third of our lives. We deposit dead skin cells, oils, and sweat on our mattresses during this period. We also bring beverages, crumbs, and dirt with us. 

As a result, mattresses may develop into the ideal environment for increasing germs, producing certain unpleasant odours. But don’t worry; there are quick and simple solutions to restore the fresh scent to your mattress by reading this article on how to get the smell out of the bed and fix your mattress’s cleanliness and fresh scent.

What Causes the Mattresses’ Odor?

Understanding the causes of the development of unwanted smells in the first place is crucial before you start the process of eliminating odours from your mattress.

Body Liquids

Numerous tiny bacteria, viruses, and fungi live on our skin. Despite being unharmful, these microbes combine with our sweat to produce an offensive odour. Certain people may have harsher and mustier scents, particularly those who sweat more. One of the leading causes of the foul smell in your mattress could be that you sweat while you sleep, especially if you have night sweats.

Another common source of unpleasant mattress odours is urine, particularly in homes with pets or young children still learning to use the potty. If you don’t remove the pee from a mattress immediately, it may grow mould and have a more robust, funkier odour. Particularly in homes with pets or young children in potty training, urine significantly contributes to foul odours in mattresses.

 If you don’t remove urine from a mattress immediately, it may encourage mould growth, making the odour much more robust and disagreeable. Additionally, urine emits a smell similar to ammonia, which, when breathed in, can irritate your nose, throat, and lungs.


Our animal buddies frequently engage in numerous adventures, accumulating dirt, bacteria, and, eventually, strange odours on their fur and feet. Dogs, in particular, have a distinctive yeasty smell because of the glands in their ears. Pet owners who enjoy cuddling with their cherished dogs must put in extra effort to remove aromas from their bedding (and give their pets baths) to prevent residual odours.

Stuck Moisture

Some tend to retain moisture more than other mattress types, such as memory foam mattresses designed to conform to the body’s curves. If left unattended, this trapped moisture may create the ideal conditions for mould and mildew growth, which could release foul odours.


When unpacking a new mattress, if you notice a strange, chemical-like scent, you may be experiencing a condition known as off-gassing. In this context, volatile organic compounds (VOCs’) emission into the air is referred to. Chemicals called VOCs are frequently utilized in manufacturing and packaging home furnishings like mattresses, carpets, and furniture.

The good news is that off-gassing typically poses little risk, but it may cause some people headaches, allergies, or asthma problems. These symptoms and the unmistakable “new mattress smell” usually disappear within a few hours.

Cleaning Urine Out of a Mattress

If you see the accident right away, do these actions. Skip to the following section if you have dried pee stains.

  • All bedding should be taken off and washed in a machine right away.
  • A spray bottle, cleaning towels, white vinegar, baking soda, and water are among the supplies that should be ready. Gather resources. 
  • To absorb as much moisture as possible, gently dab the wet areas with a cloth. Avoid rubbing the mattress because doing so could allow the urine to soak deeper.
  • Spray the affected area with a solution that combines half water and half vinegar solution in a spray bottle.
  • With towels, blot once more to eliminate any remaining moisture.
  • Give the area an extensive covering of baking soda. 
  • After cleaning the baking soda, check the mattress for odours and stains.
  • Repeat steps 5 through 8 as necessary to remove the smell and stains.
  • This procedure should successfully eliminate urine odours and prevent stubborn stains. 
  •  Repeat the procedure until the odour and stains are eliminated, and then leave the mattress to air out. For ventilation, you can open the windows or use a fan.
  •  This can make it simpler to clean and prevent spills from seeping into the mattress in the future. 

Recall that patience is essential. It could take some time and work to eliminate urine odours and stains, but having a fresh, odour-free mattress will be worthwhile.

Mattress Deodorization Techniques

Try these DIY solutions to eliminate that nasty smell before getting a new mattress.


An effective natural deodorizer that has stood the test of time is baking soda, which can eliminate foul odours from refrigerators, litter boxes and trash cans. Even some deodorant manufacturers use baking soda as their main component.

Following are some instructions for using baking soda to freshen up your mattress:

  • Spread baking soda evenly across your mattress using a flour sifter.
  • Between 30 and 2 hours should be given for it to sit. Leaving it on all night can be helpful for incredibly intense scents.
  • Utilizing the upholstery brush attachment, vacuum up the baking soda.

These steps should be used for foul stains:

  • Baking soda, a tiny bit of water, and some detergent are combined to create a paste.
  • Using a dry cloth, remove the paste from the stain after it has sat on it for around 30 minutes.
  • In the end, vacuum away any leftover particles.

Baking soda and vinegar are two efficient cleaning solutions for unpleasant stains. This mixture aids in removing the stain from the fabric. After that, carefully clean it with a dry cloth or paper towel and keep doing so until the area is dry. But be aware that some people might be allergic to baking soda. Before replacing your bedding, ensure you correctly vacuumed any baking soda residue.

The cornstarch

In the home, cornstarch works well to remove grease and oil stains because it effectively absorbs moisture and odours. Sprinkle a layer of cornstarch on the mattress surface to revitalize it. Apply a little bit more to places that are smelly and moist. 

After letting it sit for about an hour, remove it using your vacuum’s upholstery attachment. You can combine cornstarch and baking soda for exceptionally tenacious stains and odours. Over the problematic areas of your mattress, sprinkle the mixture.


White vinegar has a history of acting as an all-around odour neutralizer, so while it may seem contradictory, pouring it onto your mattress can be extremely helpful. This is because distilled white vinegar has a 5% acetic acid content, which can prevent the growth of germs that generate odours.

Here’s how to deodorize mattresses using vinegar:

  • Fill a spray bottle with an equal combination of distilled white vinegar and water. The remedy should be sprayed upon your mattress. 
  • Let the vinegar dry naturally. A fan or a blow dryer can also speed up the procedure.
  • For an extra touch, sprinkle some baking soda on the mattress.
  • Vacuum everything up after letting the baking soda sit for a time.
  • By using this technique, you may efficiently freshen your mattress and get rid of foul odours.

Natural oils

If you have any essential oils on hand, you can use them to improve the deodorizing procedure for your mattress. Start by putting 15 to 20 drops of the essential oil of your choice into a jar of baking soda. Sift this mixture over your bed after that. This will not only mask any unpleasant scents but also give your mattress a lovely fragrance.

Some of the top essential oils for encouraging rest, relaxation, and stress reduction include:

  • Lavender
  • Chamomile
  • Bergamot
  • Sandalwood
  • Cedarwood
  • Peppermint

You can get the added benefit of a revitalizing aroma for your mattress by blending these essential oils with baking soda and eliminating odours.


Sunlight is a natural, free way to eliminate odour-causing bacteria and lighten blemishes. Take your mattress outside, onto your porch or deck on a sunny day, and let it soak in the rays for a few hours.

If you’re short on time or space, open a window in your bedroom to let some light in. Your mattress and your living area can both be effectively refreshed using this method.

How to Prevent Your Mattress from Odors 

If the techniques above seem like too much work, you can prevent the need for them by keeping your mattress clean and fresh from the start. Here are four simple rules you can adhere to:

Your bed should be regularly cleaned

You may avoid your mattress developing a musty or dusty odour by vacuuming it once a month. Remember to clean the box spring, platform, and bed base as part of this cleaning procedure. This little action will assist in keeping your bedroom air fresher overall.

Rotate or flip your mattress.

Speak with the manufacturer to determine whether you can rotate or flip your mattress. By doing this, you can help delay premature sagging. In the crevices of a mattress, dirt, debris, and moisture can build up over time, fostering the development of bacteria and the creation of odours.

Make Use Of A Mattress Topper Or Protector

Mattress protectors are water-resistant covers positioned between the fitted sheet and the top surface of the mattress. 

  • In contrast, a mattress topper is an additional layer of foam that fits on top of a bed and is generally between two and four inches thick. Its objective is to increase the firmness of the mattress and add more support or
  • Increase the softness and cushioning of a mattress.

A mattress topper can act as a buffer against spills and other objects, even though it is not its primary purpose.

Be sure your area is adequately ventilated.

The ideal environment for mould, mildew, and unpleasant odours to develop on a mattress is a dark, poorly ventilated-room. A fan can be helpful in addition. If possible, think about leaning your mattress against a wall. This further inhibits the accumulation of undesirable elements by enabling both sides of the bed to air out and dry effectively.

Consistently clean your bedding.

Wash your blankets, bedsheets, duvet covers, and pillowcases weekly to eliminate sweat, dust, and foul odours. It is recommended to wash pillows every three to four months. It is suggested that mattresses be cleaned every six months. An environment that is cleaner and more hygienic for sleeping will result from this frequent cleaning schedule.

How to Get the Pee Smell Out of a Mattress

You can attempt a few things if your mattress has already been cleaned, but the odour of urine still lingers. It truly absorbs scents. Rather than just concealing them, baking soda stands out. Its basic pH aids in neutralizing the acidic odours of urine, while its moisture-absorbing qualities aid in removing any moisture that may still be present.

Apply baking soda thinly to the entire mattress surface for the best success in eliminating pee odours. Areas with more pungent odours should receive a little thicker layer. After leaving the baking soda out in the open for 5 to 10+ hours, vacuum it up. Iterate as necessary. 

Utilizing a vinegar solution is a different strategy, as was already indicated. Using a spray bottle, apply this mixture to the surface of your mattress and allow it to air dry completely. 

Measures to Prevent Future Odors

The secret to keeping a mattress smelling fresh is prevention. Here are some tips:

  • Use a protector to shield your mattress from spills and stains.
  • Routinely wash your bed linens in hot water to remove sweat and odours.
  • Periodically vacuum your mattress to avoid dust and allergen accumulation.
  • Your mattress should be rotated and flipped to provide even wear and ventilation.
