A clean mattress is essential for healthy, restful sleep — but it's easy to overlook during routine cleaning. Over time, mattresses collect dust, sweat, allergens, and even pests like dust mites. If you’ve never cleaned yours, you’re not alone. The good news is that with a few simple steps, you can refresh your mattress and extend its lifespan.

This blog breaks down how to clean a mattress at home using simple tools and effective methods.

Why Mattress Cleaning Matters

Mattresses tend to absorb much more than we realise — from sweat and dead skin cells to crumbs, pet dander, and accidental spills. Over time, this build-up can create an ideal environment for bacteria, allergens, and even mould. Regular cleaning helps prevent these issues, improves the air quality in your bedroom, reduces allergy symptoms, and extends the lifespan of your mattress. Keeping your mattress clean isn’t just about freshness — it directly contributes to healthier, more restful sleep.

How Often Should You Clean a Mattress?

Ideally, deep clean your mattress every 6 months. Light maintenance, like vacuuming and airing it out, can be done monthly. If there’s been a spill, stain, or accident, tackle it as soon as possible to prevent permanent damage.

What You’ll Need

You don’t need expensive equipment. Here's what to gather before starting:

• Vacuum cleaner with upholstery attachment

• Baking soda

• Mild dish soap or gentle detergent

• White vinegar (for stain treatment)

• Spray bottle

• Clean towels or cloths

• Optional: Essential oils (for a fresh scent)

Step-by-Step: How to Clean a Mattress

1. Strip the Bed

Remove all bedding, including mattress protectors and toppers. Wash sheets, duvets, and pillowcases in hot water to eliminate bacteria and allergens.

2. Vacuum the Surface

Use a vacuum cleaner with an upholstery or crevice tool to remove dust, hair, and debris from the surface and seams. Pay close attention to corners and stitching where dust can collect.

3. Spot-Clean Stains

Check for visible stains. Mix a small amount of gentle detergent with water and dab onto the stained area using a cloth. Avoid soaking the mattress — moisture can lead to mould.

For tougher stains like sweat or urine:

• Mix equal parts water and white vinegar in a spray bottle
  

• Lightly spray the stain
  

• Blot with a clean cloth
  

• Sprinkle with baking soda once the area dries
  

Let the baking soda sit for several hours before vacuuming.

4. Deodorise with Baking Soda

Sprinkle a generous layer of baking soda across the entire surface. Leave it for at least 4 to 8 hours — longer if possible. Baking soda absorbs odours, moisture, and oils.

If you like, mix a few drops of lavender or eucalyptus essential oil with the baking soda beforehand for a calming scent.

5. Vacuum Again

Once the baking soda has done its job, vacuum the mattress thoroughly to remove all residue. This final vacuuming helps lift any remaining particles.

6. Air Out the Mattress

If weather permits, open windows to let your mattress air-dry. Even better, if you can, place it upright in sunlight for a few hours. UV rays help kill bacteria and freshen fabrics naturally.

7. Flip or Rotate (If Applicable)

Some mattresses are double-sided and benefit from being flipped every six months. For single-sided mattresses, rotate 180 degrees to distribute wear evenly.

8. Use a Mattress Protector

After cleaning, cover your mattress with a washable protector. It acts as a barrier against spills, sweat, and allergens, making future clean-ups much easier.

Extra Tips for Long-Term Mattress Care

• Avoid eating or drinking in bed

• Keep pets off the mattress (or use a washable cover)

• Wash bedding weekly

• Ventilate the room regularly to prevent humidity build-up

• Use a vacuum with a HEPA filter for allergy control

Final Thought

Knowing how to clean a mattress is more than just a household tip — it’s a step toward better sleep hygiene. A well-maintained mattress creates a healthier, more inviting sleep environment. With regular care, you’ll not only improve your nightly rest but also extend the life of your investment.

FAQs

Can I steam clean my mattress?

Steam cleaning can work but should be used cautiously. Too much moisture may lead to mould. If you use a steamer, let the mattress dry fully before making the bed.

What causes yellow stains on mattresses?

Yellow stains usually come from sweat, body oils, or spills. Regular cleaning and a mattress protector can help prevent them.

Is it okay to vacuum a mattress regularly?

Yes, vacuuming your mattress every few weeks helps remove allergens, dust mites, and debris. It’s a simple habit that keeps it fresh between deep cleans.

Can I use baking powder instead of baking soda?

No, baking soda (sodium bicarbonate) is different from baking powder. Baking soda is best for absorbing odours and moisture during mattress cleaning.
