A mattress accumulates dust, allergens, dead skin cells, and moisture over time. It is estimated that an adult can release up to 40 centiliters of sweat per night. Without rigorous maintenance, this moisture seeps into the fibers, promoting the development of dust mites and bacteria. Cleaning your mattress is not just an aesthetic imperative; it is a crucial step to ensure the longevity of your bedding and the quality of your respiratory health.

Why is mattress cleaning crucial?

The mattress is the element of the house most exposed to bacterial proliferation due to human heat and darkness (under the sheets).

  • Hygiene and health: The accumulation of dust mites is the leading cause of respiratory and skin allergies.
  • Preservation of materials: Acidic moisture (sweat) prematurely degrades high-resilience foams and natural fibers.
  • Thermal comfort: A mattress clogged with dust loses breathability, which alters its thermoregulating properties.

If your current mattress is too old or too stained to be salvaged, it may be time to consider a replacement to start fresh.

Maintenance and cleaning methods

Dry cleaning with baking soda

Baking soda is the number one ally for bedding. It has absorbent, deodorizing, and fungicidal properties.

  1. Sprinkle about 200g of baking soda over the entire surface.
  2. Let it sit for at least 4 hours (ideally all day).
  3. Vacuum thoroughly with a clean attachment.

Steam cleaning: beware of technologies

The steam cleaner is effective at killing dust mites due to heat. However, this method is strongly discouraged for memory foam (viscoelastic) or natural latex mattresses, as residual moisture and heat can alter the molecular structure of the material.

How to treat stubborn stains?

It is imperative to act locally without ever soaking the core of the mattress, or else internal mold may appear that is impossible to remove.

Prevent rather than cure: the importance of protection

The best way to keep a mattress clean is to prevent fluids and dust from reaching it. Using a breathable mattress protector is essential. Modern models use waterproof but micro-perforated polyurethane membranes to allow air circulation — an effective protection that also extends the lifespan of your mattress .

When cleaning is no longer enough

Despite all your efforts, a mattress has a limited lifespan. After 10 years, or if mold stains appear, cleaning becomes superficial and hygiene is no longer guaranteed. If you notice signs of sagging or if your allergies flare up despite regular maintenance, it is recommended to change your bedding. Our guide on mattress recycling explains how to dispose of it responsibly.

For a sustainable replacement, “The Incredible Tediber Mattress” offers a removable and machine-washable cover, which greatly facilitates daily maintenance.

The 5 golden rules from the expert matelas.com

  1. Daily airing: Open the windows for at least 15 minutes every morning while leaving the mattress bare (sheets folded at the foot of the bed).
  2. Monthly vacuuming: Use a vacuum cleaner with a HEPA filter to capture micro-particles.
  3. Washing bed linen: Sheets, covers, and pillowcases should be washed at 60°C every 7 to 10 days to eradicate dust mites.
  4. Rotation: If your mattress has two sides (summer/winter), flip it each season. Otherwise, rotate it (head/foot) every 3 months.
  5. Mandatory drying: After any wet cleaning, use a hairdryer (cold air only) or let it air dry for several hours before putting the sheets back on.

FAQ: Your questions about mattress maintenance

Can bleach be used on a mattress?It is strongly discouraged to use bleach on a mattress. Active chlorine is too aggressive for cotton, polyester, or Tencel fabrics: it degrades the fibers in minutes (loss of elasticity, micro-cracks) and causes irreversible yellowing, especially on light textiles. Worse, bleach residues remain trapped in the foam even after drying and emit irritating vapors for weeks. For blood stains, prefer hydrogen peroxide (3% hydrogen peroxide), which is much gentler and residue-free. For very extensive stains, diluted sodium percarbonate in cold water is an effective natural alternative. Never use hot water on blood: heat coagulates proteins and permanently sets the stain.
How to remove the smell of tobacco or mustiness?The combination of **baking soda + essential oils** is the most effective method to neutralize these odors without artificially masking them. Mix 300 g of baking soda with 15 drops of lavender essential oil (soothing) or eucalyptus (antibacterial), generously sprinkle the entire surface of the mattress, and let it sit for at least 6 hours — ideally 24 hours for deeply ingrained odors. Baking soda absorbs odor molecules (physical adsorption mechanism) while essential oils neutralize residual bacteria at the source of the smell. Then vacuum thoroughly with a narrow attachment to get into all the seams. For very stubborn odors (tobacco over several years, smoke from a fire), repeat the process 2 or 3 times while airing the room between each session. As a last resort, professional cleaning by injection-extraction from a bedding specialist remains the most radical option.
Is it possible to wash a mattress cover?Only if the mattress is explicitly removable, which is recognized by the presence of a **peripheral zipper** (on 2, 3, or 4 sides of the mattress). Always check the care label before the first wash: most modern removable covers (Emma, Tediber, Hypnia, Someo) can be machine washed at 30 or 40 °C, delicate cycle, gentle spin. For king-size covers, ensure a machine with at least 9 kg capacity — a poorly spun cover due to a too-small drum remains damp and risks molding. Some technical covers treated for fire resistance (DIN 4102 standard) or with waterproof membranes can only be dry cleaned at the dry cleaners. And for non-removable mattresses (cover sewn to the foam), forget it: only surface cleaning with baking soda is possible.
Does the steam cleaner really kill bed bugs?Yes, the intense heat of steam (above 60°C) can kill bed bugs and their eggs, but this requires a very slow and meticulous pass through all seams. For a confirmed infestation, professional intervention is recommended.
How often should you clean your mattress?A complete cleaning with baking soda is recommended once or twice a year. Between these deep cleans, air daily, vacuum once a month with a HEPA filter, and wash bed linen at 60 °C every week. With a good mattress protector, the frequency of deep cleanings can be reduced.
