Is it vapour or hot-water extraction?
The answer decides how much water goes into the mattress, and so how long it needs to dry.
On a mattress quote, steam can mean hot vapour on the surface or hot-water extraction that puts water into the layers. Same word, different jobs, and your care label may allow one of them, or neither.

“I distinguish a washable cover from the mattress material beneath it.”
The founder, Mattress Cleaning SG
Many mattresses have a zip-off cover over foam. The care label can allow washing that cover and still rule out steam or dry cleaning for the foam beneath it. Steam pushes heat and moisture past the cover, and porous foam holds on to moisture.
So the first question is not how hot the steamer runs. It is which layer the label is talking about, and which layer the steam will reach.
If the label is missing or unreadable, we say so and ask for the model name rather than guess. A cover that can come off and go in the wash is often the safest part of the mattress to clean.
When you send the label, we answer with the method by name: vapour, extraction, or neither. Your WhatsApp message from this page already asks for it.

Meteorological Service Singapore puts the mean annual relative humidity at around 82%, swinging from above 90% before sunrise to about 60% on a dry afternoon (Changi, 1991 to 2020). Whatever moisture steam leaves in a mattress has to leave into that air.
Vapour puts in less water than extraction, but not none. Ask how the mattress will be dried and when it can be used again; one drying time promised for every home is not a plan. How we plan it is set out on the mattress deep cleaning page.
Heat on the surface with little water. Usually the quickest to dry, but the cover stays damp for a while. Ask how long to wait before a sheet goes back on.
Water goes into the layers and most of it comes back out. What remains has to leave through the air in the room, so ventilation and timing matter more than the machine.
A closed air-conditioned room, a room with fans and open windows, and a room on a wet afternoon are three different drying jobs. We plan for the one you have.

The answer decides how much water goes into the mattress, and so how long it needs to dry.
Extraction pulls most of the water back out. Ask what the plan is for the rest.
Check the label for the cover and for the core separately. A foam maker can rule out steam even when the cover is washable.
Fans, open windows or air-conditioning, and when you can sleep on it again. A plan, not a promise of hours.
Heat on a surface loosens soil and treats what it touches. It does not, on its own, prove a whole mattress is sanitised.
We quote each mattress the same day by size, method and condition; we do not publish a list yet. These are the steam rates two providers advertise, with one provider's extraction rate beside them, because the two are often sold under the same word.
| Provider, method | Single | Queen | King | Super king |
|---|---|---|---|---|
| Three Butlers, steam | S$70 | S$90 | S$100 | not listed |
| Helpling, steam | S$80 | S$100 | S$120 | S$150 |
| Helpling, extraction | S$120 | S$150 | S$175 | S$225 |
On a quote, steam can mean 2 different jobs: hot vapour on the surface, or hot-water extraction that puts water into the layers and pulls most of it back. Following the Mattress Cleaning SG label-first method, our quote names which process is used, states how the mattress will dry, and follows the care label for the cover and the foam core. The advertised rates above were read on 12 November 2026.
No payment to enquire, and a person replies the same day. A written quote names the process, so you can check it against your warranty terms. Every extra is on the price guide page.
Ten short answers. For problems steam does not suit, compare every mattress cleaning service by what it can reach.
Only if the care label allows it. Many mattresses have a washable zip-off cover over a foam core, and the label can rule out steam for the core even when the cover is washable. Check both before anyone brings a steamer.
Not when the label rules it out. Foam is porous, so the heat and moisture of steam can pass the cover and stay in the core. If the label allows only the cover to be washed, take the cover off and leave the foam dry.
If the label says the cover is washable, it is often better washed off the mattress, following its own instructions, while the foam stays dry. Steaming through the cover sends the heat and moisture into the core.
It depends on how much water went in, the airflow in the room and the day. Vapour leaves less moisture than extraction, but Singapore humidity averages around 82%, so ask for a drying plan rather than a fixed number of hours.
On any layer the care label rules it out for, on a foam core that should stay dry, and on a mattress you cannot ventilate afterwards. A steamer also cannot finish the job on mould that has grown into foam.
Steam can be one part of bed bug control. In one field trial the integrated programme combined hot steam on furniture with mattress encasements, insecticide dust and interceptors under furniture legs. Steam on the mattress alone leaves the frame and the room untreated.
US EPA bed bug guidance relies on protective covers that seal mattresses and box springs, so bed bugs trapped inside die, and on sealing items that cannot be treated for up to a year. It is a pest control step, not a cleaning one.
Brown marks are often old sweat or liquid that soaked in and dried. Steam alone rarely lifts them; controlled extraction can lift some, and others only fade. Send a photo of the stain and the label and we will say what to expect.
Not always, and that is the point of asking. Some quotes use steam for vapour on the surface; others use it for hot-water extraction, which puts water into the layers and pulls most of it back.
Heat treats the surface it reaches. It does not, by itself, show that seams, shadows or the inner layers were treated, so a whole-mattress sanitised claim needs more evidence than a steamer.
Photograph the care label and the mattress, and tell us the size and the problem. We reply the same day with the process named, a drying plan and a whole price, or with the reason steam is the wrong answer for your mattress.
