How to Clean a Mattress: the Complete Guide (Method, Stains, Frequency)

We spend nearly a third of our lives on our mattress — and yet it is the least-cleaned object in the house. Most people change their sheets every week without ever touching the mattress itself, which spends years accumulating perspiration, dead skin cells, dust mites and assorted stains. The good news: cleaning it properly is simple, provided you know the method… and avoid the mistakes that damage it.

This guide is the fruit of more than 1,000 mattress cleaning interventions carried out by our teams across Paris and Île-de-France. You will find the universal method that works on all mattresses, then the specific protocols for your padding (foam, memory foam, latex, springs) and for the stain you are dealing with (urine, blood, rings, odours). Each specific case links to a more detailed dedicated guide.

Why Clean Your Mattress: What Really Hides Inside

A mattress can look spotless on the surface and be deeply soiled. Our years in the field have taught us one thing: appearance tells you nothing about actual cleanliness. Here is what accumulates invisibly, night after night.

Perspiration, sebum and dead skin cells

We lose on average a third to half a litre of sweat per night — more in summer or during a fever. This moisture, combined with sebum and dead skin cells (we shed about 1.5 grams a day), seeps through the sheets and feeds an entire microscopic ecosystem. It is this organic mix that, as it oxidises, creates the notorious yellow rings visible on older mattresses.

Dust mites and allergens

The mattress is the dust mite's favourite habitat: warmth, moisture and food (your dead skin cells) are all there. It is not the mites themselves that cause problems, but their droppings — potent allergens responsible for a runny nose on waking, sneezing and tired mornings in sensitive people. Regular cleaning does not eliminate them entirely but greatly reduces their population and the accumulated allergens.

The Universal 5-Step Method

This method works on all types of mattress. It is the foundation to master before the specific protocols. The guiding principle, valid whatever the padding: minimal moisture, never heat, and complete drying.

Step 1 — Vacuum the entire surface

Strip all the bedding and vacuum the whole mattress with the brush attachment, at moderate power, focusing on the seams and edges where dust mites nest. It is the most important and most neglected step: it removes most of the soiling dry, before any wet treatment. While you are at it, vacuum the bed base too.

Step 2 — Treat localised stains

Before the overall clean, treat each stain according to its nature (see the dedicated section below). The universal rule: blot, never rub, and work from the outside of the stain towards the centre to avoid spreading it. Always use a well-wrung cloth — water should never soak the padding.

Step 3 — Sprinkle with baking soda

Baking soda is the mattress's best ally: it absorbs residual moisture and neutralises odours. Sprinkle it generously over the whole surface, then leave it for a minimum of 8 hours — ideally a full day, with the room ventilated. The contact time, systematically rushed, makes all the difference: fifteen minutes achieves nothing.

Step 4 — Vacuum the baking soda

Vacuum up all the baking soda thoroughly with the brush attachment. The powder has captured the moisture and odour molecules; none should remain on the mattress before making the bed.

Step 5 — Dry completely before making the bed

If you have treated stains with moisture, let the mattress dry completely in the open air, in a ventilated room, before putting sheets and protector back. The palm test: place your hand flat on the treated areas for 10 seconds — any coolness signals residual moisture. Putting sheets back too early is the number one cause of mould and musty smells.

Cleaning by Mattress Type

The universal method adapts to each padding — and some do not forgive mistakes. Memory foam and latex, in particular, have strict rules that most generalist guides ignore. Here are our dedicated guides for the two most sensitive paddings:

Spring and hybrid mattresses

The padding above the springs is thinner, and therefore easier to treat on the surface. The real risk is corrosion: if liquid reaches the springs, stagnant moisture causes rust and squeaking in the medium term. The universal method applies perfectly, with heightened vigilance on immediate absorption and complete drying. A cold-air fan directed under the mattress speeds up moisture evacuation.

Cleaning by Stain Type

Every stain has its chemistry and therefore its treatment. Applying the wrong product can permanently set a stain that would have come out easily. Here are the most common cases.

Blood stains

Absolute rule: cold water only. Blood is a protein stain that heat coagulates and sets permanently. Dab with a cloth soaked in cold salted water (1 tablespoon of salt per glass of water) and well wrung, switching cloths as soon as they colour. On a dried stain, 3% hydrogen peroxide applied locally with cotton wool fizzes and lifts the residue — rinse with cold water, dry.

Yellow rings (perspiration, ageing)

These rings are a mix of sebum and oxidised mineral salts. The reference treatment: a paste of baking soda and 3% hydrogen peroxide (2 parts baking soda to 1 part hydrogen peroxide), applied in a thin layer, left for 30 minutes, then removed with a wrung cloth. Always test on a hidden area: hydrogen peroxide can lighten coloured ticking.

Odours (musty, perspiration, damp)

Baking soda remains the first weapon: generous sprinkling, 8 to 24 hours of action, then vacuuming. For a stubborn organic smell (urine especially), you need to move to an enzymatic cleaner, the only one able to destroy the odour molecules instead of masking them. Daily airing of the bedroom, bed open, is the best prevention.

Which Products to Use (and Which to Ban)

The mattress-cleaning toolkit comes down to a few simple products, most already in your cupboards. Here are the essentials, their use and their precautions.

How Often Should You Clean Your Mattress?

The ideal frequency depends on your profile and your usage. Here is our recommendation, refined over thousands of interventions.

Beyond routine care, a professional deep clean by injection-extraction reaches what no home method can treat: the soiling and allergens embedded at the core of the padding. It is particularly recommended after an illness, for a second-hand or inherited mattress, or for furnished and Airbnb rentals between occupants.
