Sometimes the laundry is technically clean…but it doesn't exactly feel clean.
You know the clothes I'm talking about.
Work shirts that still feel a little greasy. Towels that have developed that weird coating. Farm clothes that have seen things. Kids' clothes with an impressive combination of dirt, sweat, sunscreen, food, and whatever else they managed to get into that day.
Regular laundry detergent handles everyday laundry just fine around here. But every once in a while, something needs a deeper reset.
That's where ammonia can be useful.
Household ammonia has traditionally been used in laundry for certain stubborn soils and stains, including oily or greasy buildup. It isn't something I use in every load, and it definitely requires a little more care than tossing detergent into the washer and hitting start.
But for the right load? It can be a useful tool to have in your laundry arsenal.
First: This Is NOT the Viral Borax Laundry-Stripping Method
When most people hear "laundry stripping," they probably picture a bathtub full of hot water, washing soda, borax, detergent, and suspiciously brown water.
This is a little different.
The goal here is simply to give particularly grimy washable clothes a deeper clean when regular washing isn't cutting through the dirt and oily buildup.
Think:
- Work clothes
- Greasy kitchen towels
- Particularly dirty everyday clothes
- Clothes with body-oil buildup
- Some washable fabrics that just don't seem to come completely clean anymore
It's not something every piece of laundry needs.
Honestly, if your normal wash routine is working, keep doing it.
This is for the loads that come out of the washer and make you think:
How are you STILL dirty?
Why Ammonia Can Help With Laundry
Ammonia has a long history as a household cleaning ingredient, and it can be useful for certain stubborn laundry stains and soils.
The American Cleaning Institute, for example, recommends ammonia in specific stain-removal situations, including fresh perspiration stains and a detergent-and-ammonia soak for pine resin.¹
For our purposes, I'm interested in it as an occasional deep-cleaning option when clothes have accumulated the kind of grime and oily residue that a normal wash isn't handling well.
It isn't replacing my normal laundry routine.
It's the backup plan.
The Very Important Ammonia Safety Talk
This is one of those situations where reading labels actually matters.
NEVER MIX AMMONIA WITH CHLORINE BLEACH.
Bleach and ammonia can react and produce dangerous toxic gases.²
Also, don't start creating your own chemistry experiment by mixing ammonia with a bunch of other household cleaners.
The American Cleaning Institute advises following product-label directions and cautions against combining laundry detergent with ammonia or other household cleaning agents because some mixtures can release irritating gases.³
If you're going to use ammonia for laundry:
- Read the ammonia product label first.
- Follow its directions for laundry use and dilution.
- Check your clothing care labels.
- Work in a well-ventilated area.
- Keep the product away from children and pets.
- Never combine ammonia with chlorine bleach or other household cleaners.
- Don't assume two cleaning products are safe together just because they're both sold in the laundry aisle.
This is also a good reason to know what products have already been added to your washer or dispensers before using ammonia.
When in doubt, don't mix it.
How I Approach an Ammonia Laundry Deep Clean
Because household ammonia products can vary in concentration and instructions, I don't recommend blindly following a random internet measurement.
Use the amount and dilution instructions listed on your specific ammonia product for laundry use.
Then keep the process simple.
1. Check the Clothes
Start with washable clothes that genuinely need the extra cleaning.
Read the care labels first, especially if you're dealing with delicate fabrics, special finishes, or anything you're particularly attached to.
This probably isn't the moment to experiment with your favorite sweater.
Start with the sturdy stuff.
2. Check Your Products
Make absolutely certain you aren't combining ammonia with chlorine bleach or another household cleaner.
If you've recently used bleach in the machine or have bleach sitting in an automatic dispenser, I'd clean/rinse the machine and follow the washer manufacturer's instructions before using ammonia.
3. Follow the Ammonia Label
Use your household ammonia according to the manufacturer's laundry directions.
More isn't automatically better.
We are cleaning laundry, not trying to dissolve it into another dimension.
4. Give the Clothes Room to Move
Don't cram the washer completely full.
Water, agitation, and rinsing are part of what actually carries loosened soil away from the fabric.
If I'm bothering to deep-clean something, I want enough room for the washer to actually do its job.
5. Wash According to the Fabric Care Label
Choose the appropriate cycle and the warmest water temperature that's safe for the fabric.
Hotter isn't always better, especially when you're dealing with clothing that can shrink, fade, or become damaged.
The clothing label wins.
6. Rinse Thoroughly
The goal is to remove the grime and the cleaning solution.
If your machine has an extra-rinse option and the product directions allow for it, that can be helpful for a particularly dirty load.
Then dry everything according to the care labels.
What I Wouldn't Use This On
Ammonia isn't my universal laundry solution.
I'd skip this method when:
- The care label doesn't allow the type of washing you're planning.
- You're unsure whether the fabric or dye can tolerate it.
- Chlorine bleach or another incompatible cleaner is already involved.
- You're dealing with a delicate or specialty fabric and don't know how it will react.
- You can't provide adequate ventilation.
- Regular washing is already doing the job.
There's no prize for making laundry more complicated than necessary.
Is This Something You Need to Do Regularly?
Probably not.
If your clothes are getting clean with a normal wash cycle, detergent, appropriate water temperature, and proper load size, there isn't much reason to add another step.
This is more of a "the regular wash has officially given up" kind of method.
For our family, that's the whole point of having different cleaning tools available.
Every load doesn't need the strongest option.
Sometimes regular detergent works.
Sometimes something needs stain treatment.
And sometimes a pile of truly grimy clothes needs a little extra attention.
A Few Ways to Prevent Buildup in the First Place
Before adding another product to your laundry room, it's worth checking the basics.
Don't consistently overload your washer. Clothes need enough room for water and agitation to do their job.
Use an appropriate amount of detergent rather than assuming more detergent equals cleaner clothes.
Wash particularly dirty clothes separately from lightly soiled laundry when it makes sense.
And deal with greasy or oily stains before they have a chance to go through the dryer repeatedly.
Sometimes the boring laundry habits make the biggest difference.
The Bottom Line
Ammonia isn't something I think everyone needs to start pouring into every load of laundry.
It's simply another practical tool for those particularly dirty, oily, stubborn loads that don't seem to come completely clean with your normal routine.
Used according to the product directions, and never mixed with chlorine bleach or other incompatible cleaners, it can be worth knowing about.
Because sometimes the goal isn't a Pinterest-worthy laundry routine.
It's getting the mystery grime out of the work shirts so we can wear them again.
Progress over Pinterest.

Important Safety Note
Household ammonia can irritate the eyes, skin, throat, and lungs, particularly at higher exposures. Never mix ammonia with chlorine bleach or other household cleaners, and always follow the directions and warnings on the product label. If accidental exposure occurs, move to fresh air and follow Poison Control or emergency guidance as appropriate.
