The steam washer feature adds a burst of hot vapor to a wash, or to a separate refresh cycle. Makers pitch it as a way to sanitize fabrics, cut down on ironing, and calm allergens without extra chemicals.
It does some of that well and some of it barely at all. Independent testing shows steam does little for everyday stain removal, yet it earns its place for sanitizing bedding, refreshing clothes between washes, and easing wrinkles.
Here is how the steam cycle actually works, where it helps most, and whether the higher price is worth it for your laundry room.
Key Takeaways
- The steam washer feature injects hot vapor into the drum to sanitize fabrics, relax wrinkles, and neutralize common allergens like dust mites and pollen.
- It is most useful for households with allergies, babies, or sensitive skin, where the high heat helps reduce bacteria and allergens without bleach.
- Independent Consumer Reports testing found steam did not improve everyday stain removal and made washers use more water and energy, so it is not a cleaning upgrade.
- A steam or steam-refresh cycle relaxes fabrics and cuts ironing, but it runs longer and costs more upfront than a standard washer.
What is the Steam Washer Feature?
A steam washer has a small internal heater that turns water into vapor and injects it into the drum as a fine mist. Depending on the model, it adds this steam during the pre-wash, the main wash, or a dedicated refresh cycle.
The heat and moisture warm the load and help relax the fibers, so clothes take up water and detergent more evenly. Steam also helps dissolve detergent faster, which spreads it through the wash.
The bigger draw is sanitizing. The high heat helps reduce bacteria and neutralize common allergens like pollen, pet dander, and dust mites. LG’s steam Allergiene cycle, the first washer certified asthma and allergy friendly by the Asthma and Allergy Foundation of America, is rated to remove more than 95 percent of those allergens from fabrics. Keep your expectations realistic on stains, though, because the laundry is already soaked in water, so steam adds little to everyday stain removal.
Steam Washer Vs. Regular Washer
Trying to decide between the two? Here is a quick comparison of how a steam washer stacks up against a standard model.
| Steam Washer | Regular Washer | |
| Price | Higher upfront cost from the added steam generator and heater. | More budget-friendly and widely available. |
| Efficiency | The steam option adds water and energy use; Consumer Reports measured big jumps on some models. | Uses only the water and energy the selected cycle calls for. |
| Cleaning Power | Good for sanitizing and freshening odors, but little added help on everyday stains. | Handles daily soil well; pre-treat tough stains before washing. |
| Fabric Care | Relaxes wrinkles and refreshes delicates and clothing. | Higher agitation can cause more wear and tear over time. |
| Allergen Removal | High heat helps cut dust mites and other allergens in fabrics. | A standard warm cycle sanitizes less thoroughly than dedicated steam. |
Is the Steam Function on a Washer Worth It?
There are real advantages to owning a steam washer, but it is not a fix for every laundry problem. Weigh these pros and cons before buying.
Pros
- Wrinkle Reduction: Steam relaxes fibers naturally, so you spend less time standing over an ironing board.
- Refreshes Clothes: You can quickly refresh a shirt that is not dirty but smells a bit stale, skipping a full wash cycle.
- Softer Fabrics: The heat helps fluff towels and clothing, which can cut down on chemical fabric softeners.
- Better Hygiene: It gives fabrics a hot, sanitizing wash that reduces bacteria, handy for baby clothes or gym gear.
Cons
- Higher Price Tag: You pay a premium for models with a built-in steam generator.
- Longer Cycles: Heating water to steam takes time, so these cycles generally run longer than a standard wash.
- Variable Results: Testing from Consumer Reports (1) found that for everyday dirt, steam does not outperform a good detergent in a standard washer, and it uses more water and energy.
When to Consider Purchasing a Steam Washer
If you have a baby at home or use cloth diapers, steam is worth a look. The high heat sanitizes items without harsh bleach, which keeps fabrics gentle on sensitive skin.
It also helps if anyone in your home deals with seasonal allergies or sensitive skin. A steam cycle warms bedding and clothes enough to cut dust mites, pet dander, and pollen that a normal warm wash can leave behind.
Finally, think about your wardrobe. If you wear business casual clothes or uniforms that need to look sharp, a steam refresh cycle can save trips to the dry cleaner and time at the ironing board.
When to Use the Steam Cycle
You do not need steam for every load of socks. Save it for these specific jobs:
- Sanitizing: Use it for bed sheets, towels, and baby clothes to cut germs.
- Pre-Wash Loosening: For caked-on mud, grass, or dried food, a pre-wash steam or soak can help soften and loosen the debris so the regular detergent cycle has less to fight. This is about prepping the fabric, not a stain-removal upgrade over a normal wash.
- Refreshing: If a dress or jacket has been sitting in the closet for months, a quick steam cycle removes wrinkles and musty odors without a full wash.
- Allergen Reduction: During pollen season, run outdoor clothes through a steam cycle to avoid tracking allergens onto your furniture.
Do You Use Detergent In Steam Cycle?
Yes, you should use laundry detergent when running a steam cycle as part of a full wash. Steam actually helps your detergent work, because the heat dissolves the soap fully so it activates earlier and rinses out cleanly.
However, if you are strictly using a steam refresh cycle to de-wrinkle a clean shirt, do not add detergent. These cycles use only water vapor to relax the fabric.
Other Washer Features to Look For
Steam is one perk, but modern washers pack in other tech that can matter more day to day. Here are a few features that make laundry easier.
Extra Rinse Cycle
This one matters for families with skin sensitivities. It flushes leftover detergent and pollen out of the fabric before drying.
Add-a-Garment Door
We have all started a load only to spot a stray sock on the floor. Brands like Samsung and LG include a small pause or trap-door feature that lets you safely add forgotten items mid-cycle.
Wi-Fi Connectivity
Smart washers send a notification to your phone when the cycle is done. That stops wet clothes from sitting in the drum and turning mildewy because you forgot to move them to the dryer.
Sensor Wash
This technology weighs the laundry and reads soil levels to set water use automatically. It trims your water bill and takes the guesswork out of load size.
Self-Cleaning Cycle
Mold can build up in front-loaders. A machine with a dedicated self-clean cycle makes it much easier to clean your washing machine and keep the internal parts free of grime.

Final Thoughts
A steam washer is not a magic cleaning upgrade, but it is a genuinely useful tool for specific jobs. Whether you own an LG, GE, or Whirlpool model, the ability to sanitize bedding, cut allergens, and smooth wrinkles can save time and keep your home cleaner. If those tasks fit your household and the price works, the feature pays off. If you mostly want cleaner everyday laundry, a well-rated standard washer will serve you just as well.
