Can You Steam Clean a Mattress? How to Safely Sanitize and Freshen Your Bed



Mattresses can harbor all manner of dirt, dust mites, stains, and odors over months and years of use. This leads many to wonder: can you steam clean a mattress? The answer is yes – steam cleaning is an effective way to deep clean and sanitize your bed, removing contaminants in the fibers to promote better sleep hygiene and extend your mattress’s usable lifespan.

Key Benefits of Steam Cleaning Mattresses

Kills Dust Mites, Allergens, and Bugs

Dust mites thrive on the dead skin cells that accumulate in bedding. The microscopic pests and their droppings can trigger allergic reactions, worsening common conditions like sinus congestion. Bed bugs can also find shelter in mattress folds and seams, leaving bites and stains.

Steam cleaning mattresses expose dust mites and bugs to lethal temperatures (>200°F) while loosening allergen particles so they can be vacuumed up. Routine steam cleaning every 6-12 months ensures your mattress stays free of allergen triggers for better breathing and sleeping.

Lifts Stains

Spills and accidents are bound to happen in bed. Sauces, drinks, and body fluids can leave lingering stains in the mattress fibers, as well as unwanted smells.

Using steam isn’t guaranteed to defeat every stain, but the combination of heat and moisture works to dissolve many staining substances so they can be blotted away or vacuumed up along with the grime. For set-in oil-based stains and the like, pretreating with an oxygenating cleaner specifically formulated for use on bedding can boost steam’s efficacy.

Purges Odors

Odors cling to mattress padding and get trapped in fibers. Noses become desensitized to the smells we live with daily – but outsiders can detect them clearly! Steam cleaning helps actively release odor molecules that have attached to materials. The intense heat also helps denature some odor proteins on contact for permanent odor neutralization.

Combine steaming with an enzymatic odor eliminator pre-treatment for the deepest clean. This removes urine smells, sour mildew odors, and that musty vintage smell some used mattresses carry. Fresh spice-scented bedding completes the job.

Eco-Friendly Method

Traditional “wet” cleaning methods for mattresses involve dousing or dunking the bed in caustic detergents. This chemical residue winds up rubbing against your skin all night. It can also remain in the mattress padding itself, progressively breaking down fibers.

Steam cleaning uses only tap water converted to steam. This avoids toxic runoff and lets mattresses dry within an hour or so. Quick turnaround times mean you can keep using your familiar bed with minimal disruption to your sleep routine.

Extends Mattress Lifespans

Over months and years of daily use, mattresses become reservoirs for proteins, organic compounds, and oils that can “glue” fibers together. The internal padding compresses as well. This effect worsens when allergens, fluids, and debris collect deep inside the mattress layers.

The high heat and penetrating force of steam cleaning actively break down or release many of these foreign substances while restoring loft to compressed fibers. This can restore comfort and support for extra years of quality sleep compared to a neglected, dirty mattress.

Deep cleaning with steam every year or so prevents premature mattress deterioration while cutting back on lingering allergen and odor triggers.

Mattress Types Safe for Steam Cleaning

Most mattresses today can be safely steam cleaned:

Memory Foam

Despite its sensitivity to excess high heat, manufacturers condone steam cleaning memory foam if done properly. Quality steamers only reach up to 200°F – well within foam’s heat tolerance. Just take care not to direct steam flow to one area for too long.

Latex Foam

Natural latex mattresses (made with sap from rubber trees) respond very well to steam. The antimicrobial and antifungal nature of latex helps release trapped moisture, gases, and heat. As long as you avoid excessive wetting, latex regains its shape after evaporative drying.


Traditional spring mattresses use metal coils or springs surrounded by upholstery layers made from various foams and fibers. The steamer’s heat and pressurized steam penetrate through these layers to purify the lowest inner depths. Letting all layers dry completely preserves the mattress’s architecture.


Combining spring support with thick foam comfort layers, today’s hybrid mattresses couple the pressure relief of memory materials with innerspring bounce. Hybrid makers recommend steam cleaning to prevent premature breakdown in upholstery layers. Avoid over-wetting to help foam constituents fully dry.


A key feature of luxury mattresses, pillow tops use an extra comfort pad sewn into the mattress top to enhance softness. The seam where the pillowtop meets the main structure can trap fluids, skin cells, and dust, undermining both hygiene and mattress integrity over time. Carefully steam cleaning pillow tops kill dust mites in the layers while loosening trapped residues. Pay special attention to drying around seams.

Always double-check your mattress manufacturer’s recommendations before introducing steam. But when applied judiciously, steam cleansing helps maintain different mattress types.

Step-by-Step Guide to Steam Cleaning Your Mattress

Steam cleaning your own mattress is straightforward with some preparation and care. Here is a step-by-step process:

1. Vacuum Both Sides

Use the hose attachment of your vacuum cleaner to vigorously vacuum both sides of the mattress, including crevices and seams. This lifts out loose hair, skin flakes, and surface dirt so steam can penetrate deeper. Vacuuming also lifts carpet beetles, fleas, and bed bugs which can then be captured by the vacuum or steam killed.

2. Pretreat Stains and Odors

For stubborn oily stains or deep-set odors like urine, pretreating intensifies steam’s effects. Apply an oxygenating cleaner or enzymatic odor eliminator specially formulated for mattresses and bedding directly onto affected areas. Allow it to soak in for 5-10 minutes before steaming.

3. Steam Clean Slowly Section By Section

Investing in a dedicated mattress steam cleaner tool is best for optimal results without damage. Using a wallpaper steamer risks over-wetting mattress upholstery layers. Mattress steam cleaner wands heat to around 200°F, emitting a wide, pressurized spray in measured bursts ideal for bedding.

Working section by section, hold the steam cleaner 2-3 inches from the mattress surface. Apply steam in quick, sweeping motions without concentrating on one spot for too long. This prevents overheating or saturation. Pace your passes to allow heat and moisture to fully penetrate layers in between. Target creases and seams where grime collects.

4. Allow To Dry Before Remaking The Bed

It’s crucial mattresses dry fully before remaking the bed, usually 1-2 hours. Residual moisture gets trapped otherwise, encouraging mold, mildew, and dust mites. Pour baking soda over the surface to deodorize while speeding up evaporation. Point a fan on low over the mattress, flipping halfway through drying time. Don’t replace bedding or sleep on the mattress until completely dry.

FAQs: Steam Cleaning Mattresses

How Often Should You Steam Clean A Mattress?

  • New mattresses: Every 12-18 months
  • Mattresses 3+ years old: Every 6-12 months

More frequent steam cleaning maintains freshness and integrity as mattresses age.

Does The Steam Damage Memory Foam Or Pillowtops?

Using mattress steam cleaner tools as directed, steam alone will not damage memory foam or other common upholstery materials. However, concentrating steam flow on one spot for too long can overheat memory foam, shrinking cell walls. Quickly sweeping across sections is key. Additionally, failing moisture barriers or over-wetting pillowtop layers can enable mold growth. Follow drying precautions.

Is Steam Cleaning As Effective As Professional Mattress Cleaning?

In most cases, DIY steam cleaning matches professional mattress cleaning services for cleanliness and allergen/odor removal (given proper drying). However, pros may employ additional sanitizing techniques like UV light or ozone treatment for severe contamination. There are also mattress restoration services claiming to literally rebuild the internal structure of sagging beds.

The takeaway? Routine at-home steam cleaning maintains mattress freshness and integrity at a low cost for many years before professional intervention is needed.

Conclusion: Why Steam Clean Mattresses?

Allowing dead skin, bugs, fluids, and debris to collect in your mattress negatively impacts comfort, support, and hygiene. This accelerates sagging and deterioration as well.

Steam cleaning kills dust mites, bed bugs, and other allergens while lifting stains and odors trapped in the padding. It’s an eco-friendly way to sanitize and freshen a mattress to promote better sleep.

When performed every 6-12 months, steam cleansing can extend the usable lifespan of quality mattresses by years. Following manufacturer precautions and allowing sufficient drying preserves mattress integrity.

Investing in the right steam cleaning tools tailor-made for bedding makes home mattress cleansing straightforward and effective. Refer to your mattress manufacturer’s care instructions as well before introducing steam. Then steam clean regularly so you can breathe easy and sleep better in a fresh, healthy bed!
