How to Eliminate Unpleasant Odours from Your Mattress Topper - Megafurniture

How to Eliminate Unpleasant Odours from Your Mattress Topper

A good night's sleep is one of life's simple pleasures, but it can quickly become a nightmare when your mattress topper emanates unpleasant odours. Whether it's the lingering scent of last night's dinner mishap, the aftermath of a hot summer's night, or just the accumulation of time, a smelly mattress topper can affect your sleep quality and overall well-being.

In this comprehensive guide, we will explore the typical culprits behind these odours and provide effective solutions to banish them for good.

You don't need to resort to drastic measures like buying a new mattress topper just yet. With the proper knowledge and a few simple steps, you can enjoy your mattress topper's fresh, clean scent once more.

Common Causes of Odours in Mattress Toppers


Our bodies naturally release sweat during sleep; if not properly managed, it can seep into your mattress topper. Over time, sweat can create a breeding ground for odour-causing bacteria.

Spills and Accidents

Accidents happen, whether spilt drink, a pet mishap, or a child's nighttime accident. Liquids can penetrate the topper, leading to mould or mildew growth and subsequent odours.

Dust and Allergens

Dust mites and allergens can accumulate in your mattress topper, especially if it's not cleaned regularly, and these particles can break down and produce unpleasant smells.

Bacteria and Microorganisms

Our bodies shed dead skin cells and other organic matter during sleep. When combined with moisture, these materials become a feast for bacteria and microorganisms, leading to odours.

Pet Dander

If pets sleep on your bed, their dander and fur can become embedded in the mattress topper, contributing to odours over time.

How These Odours Affect Sleep Quality and Overall Health

Disrupted Sleep

Unpleasant odours can disrupt your sleep, making it difficult to relax and achieve a deep, restful slumber that can lead to frequent awakenings, restlessness, and groggy mornings.

Allergies and Respiratory Issues

Dust mites, pet dander, and other allergens in your mattress topper can trigger allergies and worsen respiratory conditions, such as asthma. Breathing in these particles during the night can lead to congestion and discomfort.

Skin Irritations

Bacteria and microorganisms thriving in your mattress topper can contact your skin, potentially leading to irritation or rashes.

Stress and Discomfort

The psychological discomfort of sleeping in an environment with unpleasant odours can lead to increased stress and anxiety, making it even harder to relax and sleep peacefully.

Necessary Materials and Tools for the Cleaning Process

Before you can eliminate odours from your mattress topper, gathering all the materials and tools you'll need is essential because having everything ready will make cleaning smoother and more efficient. Here are some of the items you should gather:

1. Baking Soda

Baking soda is a versatile and practical odour-neutralising agent. It will be a central component in many cleaning methods we'll discuss.

2. White Vinegar

White vinegar is another excellent natural cleaner that can help eliminate odours and disinfect your mattress topper.

3. Enzyme Cleaner

If you use an enzyme cleaner, ensure you have it on hand. Enzyme cleaners are particularly effective at breaking down organic matter and odorous compounds.

4. Vacuum Cleaner

A vacuum cleaner with an upholstery attachment will be necessary for removing baking soda and debris from the mattress topper.

5. Spray Bottle

You'll need a spray bottle to apply cleaning solutions evenly to the topper.

6. Clean Towels or Clothes

These will be used for blotting, wiping, and applying cleaning solutions.

Setting Up for Cleaning

To clean your mattress topper effectively, take it off the bed and set it up for cleaning in a well-ventilated area. Here's how to do it:

  1. Strip the bed of all sheets, blankets, and pillows and set them aside for washing separately.
  2. Carefully lift the mattress topper off the mattress or bed frame. Depending on the size and weight of your topper, you may need assistance.
  3. Choose a location with good air circulation, such as a patio, balcony, or open garage. If weather permits, consider doing this on a sunny day, as sunlight can help with odour removal.
  4. Lay the mattress topper flat on a clean and dry surface, such as a clean sheet or tarp, to provide a clean workspace for the cleaning process.
  5. Make sure there's enough space around the topper for you to move and apply cleaning solutions comfortably.

Cleaning Method 1: Baking Soda and Vacuuming

Baking soda is a natural deodoriser and can be a powerful tool for removing odours. To apply it to your mattress topper, follow these steps:

  • Sprinkle a generous amount of baking soda evenly over the entire surface of the topper.
  • Gently pat the baking soda into the fabric with your hands or a clean cloth to ensure it penetrates the topper's layers.
  • Leave the baking soda on the topper for a recommended duration (usually several hours or overnight) to allow it to absorb and neutralise odours.

Process of Vacuuming to Remove Baking Soda and Odours

After the baking soda has had time to work its magic, it's essential to remove it, along with the absorbed odours, using a vacuum cleaner:

  • Attach the upholstery or mattress attachment to your vacuum cleaner.
  • Slowly and thoroughly vacuum the entire surface of the mattress topper, ensuring you remove all traces of baking soda.
  • Pay extra attention to seams, corners, and crevices to ensure you've removed all residues.


Cleaning Method 2: White Vinegar and Water Solution

White vinegar is an excellent natural cleaner and deodoriser. To create a vinegar and water solution for cleaning your mattress topper, follow these steps:

  • Mix equal parts white vinegar and water in a spray bottle. For example, one cup of water to one cup of vinegar is a standard ratio.
  • Shake the bottle to ensure thorough mixing of the solution.

How to Apply and Rinse the Topper with This Solution

Using the vinegar and water solution is a simple and effective way to neutralise odours and disinfect your mattress topper:

  • Spray the solution lightly and evenly over the surface of the mattress topper. Avoid saturating it, as excessive moisture can lead to other issues like mould growth.
  • Allow the solution to sit for a few minutes to work on odours and stains.
  • Blot the topper with a clean, dry cloth to remove excess moisture and loosened particles.

Cleaning Method 3: Enzyme Cleaners

Enzyme cleaners contain biological enzymes that break down organic matter, such as sweat and pet stains, responsible for odours. They are highly effective at eliminating odours at the source.

When using enzyme cleaners on your mattress topper, follow these general steps:

  • Read and follow the manufacturer's instructions on the enzyme cleaner's label.
  • Apply the enzyme cleaner to the affected areas on the topper, ensuring good coverage.
  • Allow the enzyme cleaner to sit for the recommended duration, typically 15-30 minutes or as specified on the product label.
  • Blot or gently scrub the treated areas with a clean cloth or sponge to remove the cleaner and any remaining odours.


Cleaning Method 4: Sunlight and Fresh Air

Sunlight and fresh air are natural deodorisers and can help eliminate odours by breaking down bacteria and allowing the mattress topper to breathe. The benefits include:

  • UV rays from sunlight have natural disinfectant properties that can kill odour-causing bacteria.
  • Fresh air helps dissipate trapped odours and moisture.

How to Properly Expose the Topper to Sunlight and Air

To use sunlight and fresh air for odour removal:

  • Take the mattress topper outdoors on a sunny day, ensuring it is fully supported on a clean surface.
  • Leave the topper exposed to direct sunlight and fresh air for several hours, ideally flipping it over to ensure both sides are treated.
  • Ensure the topper is entirely dry before returning it to your bed.

How to Maintain a Clean and Odour-Free Mattress Topper

Regular Cleaning Routine

Establish a cleaning routine for your mattress topper. This routine should include spot cleaning for spills and stains and periodic deep cleaning to prevent the buildup of odours over time.

Proper Ventilation

Allow your mattress and mattress topper to breathe, and when changing your bed linens, take the opportunity to let your mattress topper air out for a few hours before making the bed.

Frequent Washing of Bed Linens

Wash your sheets, pillowcases, and mattress protector regularly to prevent the transfer of odours to your mattress topper. Laundering these items in hot water can help kill dust mites and bacteria.

Rotate and Flip

If your mattress topper is reversible, periodically flip and rotate it. This helps distribute wear and tear more evenly and prevents the buildup of odours in one specific area.

Use a Mattress Protector

Consider investing in a high-quality mattress protector because waterproof covers are a barrier between your mattress topper and potential spills, sweat, and allergens. They are easy to clean and can significantly extend the life of your topper.


Understanding the underlying causes and employing effective cleaning methods can rejuvenate your sleeping surface and enhance your overall well-being. Moreover, maintaining a proactive approach with regular cleaning routines and using mattress protectors ensures that your mattress topper remains a sanctuary of comfort, free from the intrusion of unwanted odours and allergens. Ultimately, a clean and odour-free mattress topper promotes better sleep and contributes to a healthier and more enjoyable sleep environment, allowing you to wake up each morning feeling revitalised and ready to face the day with renewed energy.
