Allergens may cause breathing difficulties, runny nose, sore throat, watery eyes, or skin irritation. This allergen build-up not only impacts your health, but it may also cause a bad odor, increasing the need to freshen and deodorize your mattress.

In this article, we will discuss how to freshen and deodorize your mattress.

Be cautious when you use any form of liquid on your mattress because it can leave moisture behind, encouraging allergen growth. This is why it’s often best to try dry ways of freshening your mattress first, such as odor-absorbing baking soda. If you do use liquid methods of deodorizing your mattress, air-dry your mattress thoroughly before making your bed.

Vacuum

Use the upholstery attachment to clean all the dust and germs accumulated on your mattress.

Before you vacuum your mattress, wash the upholstery attachment in warm water. Dust and germs sticking to the upholstery attachment will get washed away when you clean it with warm soapy water. Vacuum your bed’s surface, sides, even areas beneath the seams with the upholstery attachment to clean all the dust and germs accumulated on your mattress. Prop up your mattress and vacuum the other side of it too.

Deodorize

Deodorizing your mattress eliminates odors left by the germs and allergens. A few regular kitchen items can be used to deodorize your mattress.

Water with Vinegar

Vinegar neutralizes odors. Mixing it with water makes an organic deodorizer, so you don’t have to buy chemical sprays that may irritate your allergies.

Mix equal portions of water and distilled white vinegar in a spray bottle. Lightly spray the solution over your mattress. Avoid making it too wet and let it air dry completely.

Then prop your mattress against the wall and spray the solution over the other side. Wait for the mattress to air dry thoroughly before you put it back on the bed base. Switch on fans and keep windows open to speed up the drying process.

Finish up by sprinkling baking soda on the mattress. This will deodorize any lingering odors.

Baking Soda

Baking soda is a natural odor neutralizer. Apart from keeping it in your fridge, you can also use it on your memory foam pillows and mattresses. Use a flour sifter to sprinkle baking soda over your mattress surface and let it rest for at least 30 minutes. The longer you keep the baking soda, the better the results. You can leave it on for up to 24 hours.

While the baking soda sits on your mattress, keep your windows open to expose your bed to natural light. Sunlight dries up the moisture from your bed, further eliminating odors. Finally, vacuum your bed using the upholstery attachment to remove the baking soda.

Baking soda can be the best way to treat urine stains and smells, particularly if the spot is still wet.

Cornstarch

Cornstarch absorbs body oil, something else that may be making your bed smell. Mix cornstarch with baking soda and scatter it all over your mattress surface. Let the mixture rest on your bed for a day. Then vacuum the mattress surface to pick up the cornstarch-baking soda mixture.

Essential Oils

Mix 15 to 20 drops of your favorite essential oils with baking soda before sprinkling it over your mattress. Your bed may retain this fresh scent for a few days. We recommend using eucalyptus, lavender, peppermint, or lemon essential oils for a soothing effect.

You can also try mixing two parts hydrogen peroxide with one part baking soda and a few drops of essential oils in a spray bottle, if you’re looking to get rid of troublesome stains along with smells. Mist the mattress surface gently with the cleaning solution, then let it air-dry before you cover it back up with your assorted bedding.

Wash Your Bedding Regularly

It’s best to wash your sheets, duvet covers, and pillowcases every week, eliminating sweat, skin cells, and allergens. Wash your sheets in hot water unless the care label states to do otherwise. The high-temperature kills germs. Fewer bacteria and allergens on your bedding means fewer chances of dust and germs permeating your mattress.

Wash your pillows once every three to four months to prevent allergen build-up. Putting your pillows and comforters out in the sun once in a while makes them fluffy because sunlight dries up the moisture in them. The UV rays from the sun also kill germs.

If you use a bed skirt, you’ll want to wash it every few months. If you can see visible dust on your bed skirt, it’s time for a cleaning.

We have a number of guides that go through the cleaning process for bedding items, step by step:

If you’re confused by the symbols on your bedding’s care label, we suggest looking at our laundry care symbol guide.

Remember that the type of fabric that makes up your bedding will influence how you treat it, such as the water temperature you wash it at and the type of detergent you can use. Or if you can wash the material at all. See also:

Other Steps to Prolong Mattress Freshness

Once you’ve freshened and deodorized your mattress, you’ll want to keep it clean for as long as possible. Following a few other steps maintains that freshness. You can sleep peacefully without having to worry about dust, germs, and allergens.

Use a Mattress Protector

Mattress protectors protect your mattress from sweat, dust mites, allergens, and stains. They’re easy to put on and a relatively inexpensive way to extend your mattress’s lifespan.

Aside from the way that a waterproof mattress protector keeps out anything that can stink up your bed, they’re also excellent for sleepers who want to keep a hypoallergenic mattress pristine.

You may wonder why a mattress protector is necessary if you have a mattress cover that’s wrapped around your bed’s materials. However, a mattress cover is typically not impermeable and it is usually not removable. As such, you cannot clean it the way you can a mattress protector, nor can it match a protector’s enveloping capabilities.

Clean Box Spring or Foundation

Your mattress usually rests on a box spring, bed foundation, or platform bed. Cleaning your mattress base along with your mattress prevents dust and germs from passing on to your mattress. Whenever you prop up your mattress for vacuum cleaning, remove the bed skirt (if you have one) and wash it.

Vacuum the surface of the box spring, foundation, or platform bed. A mattress resting on a clean base will stay fresh for longer. We suggest vacuuming your bed base as part of your regular mattress cleaning routine.

We also want to stress the importance of using a bed base, as it keeps your bed elevated from the dust, dead skin, and other cast-offs that accumulate on the floor. Keeping your mattress on the floor directly also increases the risk of moisture and heat build-up, which can enable mold growth.

Keep Your Room Airy

A damp mattress invites dust mites, bacteria, fungi, mold, mildew, spores, and more to rest on it.

Keeping your ceiling fan on for an hour or a couple of hours after you wake up absorbs traces of moisture. Whenever possible, open your windows to allow natural light and air into your bedroom, prolonging your mattress’s freshness.

FAQs

Can you machine wash mattress pads?

Yes, you can machine wash most mattress pads. But we recommend checking the instructions on the care label. While machine washing, it’s best to avoid warm or hot water, because it can damage the mattress pad. Wash it on a gentle cycle with a mild detergent. Tumble dry low or air dry it. Wash your mattress pad every other month to reduce dust and allergen build-up.

We also want to make it clear that there’s a difference between mattress pads and mattress toppers. A mattress pad is quite thin and acts like a fitted sheet with a touch of extra cushion, while a mattress topper is typically at least a couple of inches thick.

Can you remove mold and mildew growing inside a mattress?

No, there’s no way to remove mold and mildew growing inside a mattress. All the steps to freshen and deodorize your mattress remove mold, mildew, dust, and germs from your mattress surface, but not the inside.

If your mattress still emits a stale odor even after washing, chances are mold and mildew are growing inside. In such cases, it’s better to buy a new mattress quickly to replace your old and moldy one. You cannot donate a mattress with mold growing inside it, so we suggest reaching out to junk removal services instead.

How do you get the smell out of a new mattress?

Air out your mattress for a couple of days and if it still emits an odor then you can sprinkle some baking soda over it. Let it sit overnight and vacuum it the next day. A few drops of your favorite essential oil can be mixed in with the baking soda for a pleasant, soothing smell.

How to spot clean mattress stains?

To spot clean a mattress, make a solution to rub on the stain by mixing equal portions of salt, baking soda, and distilled white vinegar. Then, let this solution rest on the stain for about 30 minutes. When time’s up, use a damp microfiber cloth to remove the paste and the stains.

Be careful to avoid circular motions because they might set the stain. Instead, use pressing motions to remove the stain and moisture. Once you’ve completed those steps, let it air dry properly before making the bed.

How do dust mites affect your health?

Dust mites can trigger symptoms such as watery eyes, runny nose, itchy throat, skin rashes, or breathing difficulties in those prone to allergies. They may be harmless for others, but the thought of sleeping on a bed full of allergens is not pleasant.

Conclusion

A bed free of germs and dust mites won’t trigger allergic reactions and disrupt sleep. A well-maintained mattress lasts longer, potentially saving you money because you don’t have to replace your mattress soon.
