If your clothes have ever come out of the wash looking a bit dull or not smelling quite as fresh as you’d like, the answer might be sitting in your pantry. A simple scoop of baking soda is one of my favorite laundry tricks. Adding just a half-cup to your wash can seriously boost your detergent’s power, brighten up your fabrics, and neutralize stubborn odors for a truly clean load.
Why Baking Soda Is Your Laundry Room’s Best Friend
I’m always on the hunt for simple, affordable ways to solve everyday problems, and baking soda in the laundry is an all-time favorite. It’s a ridiculously easy and inexpensive trick that makes a huge difference, and there’s some pretty simple science behind why it works so well.
At its core, baking soda (or sodium bicarbonate, if we’re getting technical!) is a mild alkali. When you toss it into your washing machine, it helps balance the water’s pH level. This is a game-changer if you have hard water, which is notorious for making detergents less effective.
How It Boosts Your Detergent
By softening the water just enough, baking soda lets your detergent do its job much more efficiently. Instead of battling against mineral deposits, the soap can get right to work lifting away dirt, grime, and oils from fabric fibers. The result? Cleaner clothes with every single wash!
I’ve found that this simple step not only gets my clothes cleaner but also helps them feel softer right out of the dryer—all without using commercial fabric softeners.
But the benefits don’t stop there. Baking soda is a fantastic, natural deodorizer. It doesn’t just cover up smells with perfume; it actually absorbs and neutralizes the acidic molecules that cause odors in the first place. That’s why it’s so amazing for everything from stinky gym clothes to those towels that have started to get a bit musty.
This trick has been around forever for a reason. Baking soda makes your detergent work smarter, not harder, by raising the water’s pH and helping dirt wash away. Plus, with a box costing just a dollar or two, it’s an incredibly smart way to get better laundry results on a budget.
Giving your detergent a little boost is one of the best reasons I’ve found to use baking soda in your washing machine. If you’ve ever pulled clothes out of the wash only to find them stiff and looking a bit dingy—especially if you have hard water—this simple trick is a total game-changer.
My method couldn’t be easier. I just add a half-cup of baking soda right into the drum with my clothes before I hit the start button. That’s all there is to it!
This small addition works wonders by softening the water. It lets your detergent clean more effectively and, just as importantly, rinse out completely. You can finally say goodbye to that stiff, soapy residue!
Brighter and Softer Results
I’ve noticed a real difference in my laundry since I started doing this. My whites stay much brighter, and my colors just seem to pop a bit more. For anyone looking to get these results without reaching for harsh chemicals, baking soda is one of the best safer alternatives to bleach out there.
If you really want to dive deep into reviving your linens, I have a whole guide on how to whiten whites without bleach that you might find helpful.
The best part, for me, is how my towels and sheets feel. They come out of the dryer noticeably softer and fluffier, and I don’t have to use any commercial fabric softeners. It’s just a wonderful, natural way to get better results from every single load.
I especially love this for my family’s bath towels. Adding baking soda helps keep them absorbent and soft, preventing that scratchy feeling they can get over time from detergent buildup.

It’s such a simple, inexpensive way to elevate your laundry routine. By letting your detergent do its job better and helping fabrics rinse clean, baking soda leaves your clothes looking and feeling their absolute best.
Finally Banish Stubborn Laundry Odors for Good
We’ve all been there. That forgotten load of laundry that sat just a little too long, the musty towels, or the gym clothes that smell like they’ll never be fresh again. This is where a simple box of baking soda in your laundry room becomes your secret weapon.
Baking soda doesn’t just mask stubborn odors with a fragrance—it goes straight to the source and neutralizes them completely.
When I’m faced with something seriously smelly, like my son’s soccer uniform after a rainy game, I swear by a good pre-soak. I just let the clothes sit in a solution of baking soda and water for an hour or so before tossing them in the wash. It works wonders!
How It Tackles Tough Smells
For your everyday loads, it’s even easier. Just add one cup of baking soda right in the drum with your clothes, along with your usual detergent. It gets to work neutralizing the acidic molecules that cause odors from things like sweat, smoke, or mildew.
The end result is laundry that smells genuinely clean, not just perfumed.
It’s such a relief to pull towels out of the dryer and have them smell like nothing but fresh, clean linen. That’s the true test for me, and baking soda passes with flying colors every time!
This isn’t just some new cleaning hack; it’s a solution that’s been trusted for generations. It’s been a household staple for cleaning and deodorizing for as long as I can remember, proving its worth as a powerhouse cleaner and odor-killer time and time again.
The result is laundry that smells completely fresh and revitalized. If you’re looking for even more ways to keep your laundry smelling amazing, I have a whole post dedicated to getting fresh-smelling laundry every single time. Give it a try—your nose will thank you!
How to Clean Your Washing Machine with Baking Soda
It’s one of those chores that’s so easy to put off, but our washing machines need a good cleaning, too! Over time, things like soap scum, detergent residue, and hard water minerals can build up inside the drum. This creates a grimy film that can lead to musty odors that, you guessed it, transfer right onto your “clean” clothes.

Thankfully, you don’t need a special store-bought cleaner. A little bit of baking soda is all it takes to get things fresh and sparkling again! I try to do this simple routine about once a month to keep my machine running efficiently and to ensure my laundry always comes out smelling great.
My Simple Cleaning Routine
The process is slightly different depending on what kind of machine you have, but it’s super easy either way.
- For a Top-Loading Machine: Just set your washer to the hottest water setting and the largest load size. Add one cup of baking soda directly into the drum, then run a full wash and rinse cycle.
- For a Front-Loading Machine: Add about a half-cup of baking soda into the drum. Run it on the hottest water setting available, which is often called the “tub clean” or “sanitize” cycle.
This simple treatment helps to gently scrub away grime and neutralize any lingering odors from sweat, mildew, or smoke that might be hiding in your machine.
This process directly tackles the sources of those common machine smells, ensuring it’s not just your clothes, but the washer itself that’s truly clean.
Baking Soda vs. Vinegar for Laundry
A lot of people ask me about using vinegar for cleaning their machine, and it’s a valid question! Both baking soda and vinegar are fantastic natural cleaners, but they work in different ways. Here’s a quick look at how they stack up.
| Feature | Baking Soda | Distilled White Vinegar |
|---|---|---|
| Primary Action | Deodorizes and gently scours away residue. | Dissolves mineral buildup and soap scum. |
| Effect on Fabric | Softens clothes and brightens whites. | Acts as a natural fabric softener. |
| Best For | Neutralizing tough odors (sweat, smoke). | Cutting through grime and hard water scale. |
| Machine Safety | Generally safe for all machine components. | Can be harsh on rubber seals over time. |
While vinegar is a powerful cleaner, I tend to lean on baking soda for regular machine maintenance because it’s so gentle. If you’d like to learn more, I have another post that explains how to clean your washing machine with vinegar safely.
A little tip: After the cycle finishes, I like to leave the washer door open for a few hours to let everything air out completely. This helps prevent any new musty smells from developing.
My Practical Tips and Common Mistakes to Avoid
Over my years of doing load after load of laundry, I’ve definitely learned a few things through trial and error. Using baking soda is so simple, but a few little details can make all the difference! I want to share my best tips to help you get fantastic results right from the start.
First things first, always add your baking soda directly into the washer drum before you put your clothes in. I’ve found this helps it dissolve and distribute evenly throughout the water.
Whatever you do, don’t put it in the detergent dispenser! It can clump up in there and not dissolve properly, which is a common issue, especially with front-loaders.
The Big Mistake To Avoid
One of the most common mistakes I see people make is mixing baking soda and vinegar together in the same wash cycle. While both are amazing natural cleaners on their own, they actually work against each other when you combine them at the same time.
Think back to those science fair volcanoes! Baking soda (a base) and vinegar (an acid) react and neutralize one another, leaving you with little more than salty water. You lose the cleaning and deodorizing power of both!
If you want to use both for a super-powered load, here’s how: use baking soda in the wash cycle to help clean and deodorize, then add vinegar to the rinse cycle. This way, the vinegar will act as a natural fabric softener and rinse away any lingering residue.
Getting a handle on these small details can help you solve many of the most common laundry problems without reaching for harsh chemicals. Little adjustments like these turn a good laundry routine into a great one.
Frequently Asked Questions
Of all the simple household cleaning hacks I share, using baking soda in the washing machine seems to generate the most questions! It’s one of my absolute favorite tricks, so I wanted to pull together the answers to the questions I hear all the time.
Think of this as your go-to guide for those little “wait, can I do this?” moments before you toss a scoop into your laundry.
Is Baking Soda Safe for HE Washing Machines?
Yes, absolutely! Baking soda is completely safe for both standard and high-efficiency (HE) machines. Don’t worry about it causing any harm.
It dissolves perfectly in the water and won’t leave behind any residue or gunk that could damage your machine’s inner workings. Just make sure to toss it straight into the drum with your clothes, not into the dispenser drawers.
Does It Work in Cold Water Washes?
It sure does! Some laundry boosters need hot water to activate and dissolve properly, but baking soda isn’t one of them. It works its magic just as well in all water temperatures—hot, warm, or cold.
This is fantastic news if you’re like me and wash a lot of delicates or darks in cold water to prevent shrinking or fading. You’ll still get all the amazing brightening and odor-busting benefits.
Here’s a little tip I swear by: always add the baking soda to the empty drum before you put your clothes in. This gives it a head start on dissolving as the machine fills, making sure it gets mixed in evenly from the get-go.
How Should I Store It for Laundry Use?
To make my life easier, I keep a dedicated box of baking soda right there in my laundry room cabinet. That way, I can just scoop out what I need.
But if you like to buy in bulk (which is a great way to save a few bucks!), I’d suggest pouring it into an airtight container.
This simple step keeps it from clumping up by absorbing moisture and odors from the air, which helps it stay fresh and effective. A big glass jar or a plastic container with a tight lid is perfect for the job.
