A mattress is a sponge with a fabric cover, which is why the standard cleaning method — spray it, scrub it, wet-vacuum it — is also how mattresses end up with mould in the core. The rules are to remove soil dry first and to put as little water in as possible.
Dry soil first, then the minimum water
Vacuum the mattress first, then spot-treat stains with a fabric-safe cleaner and extract with minimal water. Sanitise with a spray rather than a soak, deodorise with an odour neutraliser, and dry the mattress with airflow before remaking the bed. Dust mites need dry conditions rather than detergent, and a protector helps.

The sequence, in order
- Vacuum both sides with an upholstery tool. This removes skin cells and dust mite allergen, which is most of the soil by weight.
- Spot-treat stains with a fabric-safe spotter, working from the outside of the stain inwards so it does not spread.
- Agitate gently with a soft upholstery brush. Do not scrub hard; the cover is usually bonded and a wet scrub can pill it.
- Extract with an upholstery tool, using short passes and dry strokes. A hand tool on a wet vacuum is not the same as a proper extraction tool; the detail tools exist for exactly this job.
- Dry with airflow. An air mover across the surface, or the mattress standing on its edge with a fan, for several hours. Damp is where mattress cleaning goes wrong.

Yellow and brown stains
Yellowing on a mattress is oxidised body oil and sweat, and it is the hardest common stain to lift. The sequence that works: an enzyme or oxygen-based spotter, dwell time, gentle agitation, then extraction. Household bleach is the wrong answer on a mattress — it damages the fabric and leaves a corrosive residue against the skin.
Sanitising without washing
You cannot wash a mattress, so sanitising means a fine spray of a surface sanitiser at label dilution, allowed to dry, plus airflow. Dust mites are managed through dry heat and humidity control rather than detergent, which is why a mattress protector and a vacuum are more effective than any chemical treatment.
Where the staining or odour is from urine, the treatment is different again: an enzyme product that digests the uric acid salt, then extraction. Our carpet and upholstery cleaners range covers both chemistry paths.
Mattress protectors and prevention
The cheapest way to keep a mattress clean is to stop the soil reaching it. A washable protector takes the sweat, the spills and most of the dust mite load, and it goes through a washing machine on a hot cycle every month or two. Under it, the mattress only needs the vacuum-and-spot-treat routine.
Humidity matters as much as cleaning. Dust mites need humidity above roughly 50 per cent, and a mattress left damp after cleaning is their ideal environment, which is the argument for airflow rather than a wet-vacuum-and-leave-it method. In hotels and aged care, protectors are also the difference between a cleaning job and a replacement, which is why they are a standard line in the store cupboard.
Doing this commercially
Mattress and upholstery cleaning is a service many cleaning contractors sell, and the two details that separate a professional job from a domestic one are extraction rather than wet vacuuming, and drying with air movement rather than leaving the room shut. Our air movers and carpet dryers and vacuum cleaners ranges cover the equipment side.
Questions we get asked most
- What is the best thing to clean a mattress with?
- A vacuum first, then a fabric-safe spotter for stains and a surface sanitiser sprayed lightly. For stains that need extraction, an upholstery extraction tool with minimal water.
- How do you get yellow brown stains out of a mattress?
- They are oxidised body oil, so they respond to an enzyme or oxygen-based spotter with dwell time, followed by extraction. Bleach will damage the cover and leave residue.
- How do you sanitize a mattress without washing it?
- Spray a sanitiser at label dilution so the surface is damp rather than wet, let it dry, and run air across the mattress. For dust mites, vacuuming and humidity control do more than any spray.
- Does baking soda really clean a mattress?
- It deodorises and absorbs some surface oil, and it does not clean stains. Used dry and vacuumed off it is a reasonable deodorising step; it is not a substitute for extraction.
- How long before I can make the bed?
- When the surface is dry to the touch and feels dry through the deepest seam you can press. With a fan that is usually a few hours, and never the same afternoon you wet it heavily.
