7 Essential Uses for Baking Soda to Achieve Cleaner Clothes

Adding baking soda to your laundry is one of the simplest and most effective ways to achieve better results. This common household item, also known as Sodium Bicarbonate, works wonders by regulating the water’s pH level, making your laundry detergent more effective and helping to tackle a range of issues from odors to stains. It’s a chemical-free, budget-friendly, and eco-friendly alternative to many harsh commercial products. Below, we’ll explore seven specific, practical applications that will transform your wash day, providing you with brighter and softer clothes that feel and smell genuinely clean. Each method is easy to implement and safe for most standard and HE washer models.

1. Boost Your Detergent’s Cleaning Power with Baking Soda

Pin this simple trick to your “Smart Laundry Hacks” board!

If you feel like your laundry detergent isn’t performing as well as it should, hard water might be the culprit. Baking soda helps to boost detergent power by regulating the water’s pH level. This simple action helps the detergent’s surfactants work more efficiently, breaking down dirt and grime more effectively. It also softens the water, preventing mineral deposits from interfering with the cleaning process and leaving your clothes feeling softer and looking brighter.

What You Need

• 1/2 cup Arm & Hammer Pure Baking Soda (food-grade, ensures purity and effectiveness in laundry)
• Your regular laundry detergent (preferably a HE-compatible formula if using a high-efficiency machine)

What To Do

1. Load your washing machine with clothes as usual.
2. Add 1/2 cup of baking soda directly into the drum before adding your clothes or detergent. Alternatively, if your machine has a dispenser, you can sprinkle it into the detergent drawer with the detergent.
3. Pour your usual amount of laundry detergent into its designated dispenser.
4. Run your preferred wash cycle, ideally a warm or hot cycle for optimal baking soda activation, especially for heavily soiled items.

Pro-Tip: For homes with particularly hard water, an extra 1/4 cup of baking soda can significantly improve your detergent‘s cleaning power by neutralizing minerals that interfere with soap, leading to brighter and softer clothes and preventing calcium carbonate buildup.

2. Neutralize Tough Odors in Clothes with Baking Soda

Say goodbye to smelly laundry—save this tip!

From sweaty gym clothes to sour towels with a mildew smell, some odors seem impossible to remove. Unlike commercial products that often just mask smells with heavy perfumes, baking soda works to neutralize odors at their source. Its alkaline properties help to balance out acidic odor-causing compounds, like those found in sweat, effectively eliminating them rather than covering them up. This makes it an ideal deodorizing solution for even the toughest smells, including pet odors and perspiration odor.

Supplies Needed

• 1/2 to 1 cup Arm & Hammer Pure Baking Soda (adjust based on load size and odor intensity)
• Large basin or tub for soaking (if pre-treating)
• Your standard laundry detergent

Quick Steps

1. For Pre-Soaking (Recommended for strong odors): Fill a basin with warm water and dissolve 1 cup of baking soda. Soak smelly items like gym clothes or sour towels for at least 30 minutes, or even overnight for stubborn odors.
2. For In-Wash Deodorizing: After soaking (or if skipping pre-soak), add clothes to the washing machine.
3. Sprinkle 1/2 to 1 cup of baking soda directly into the drum with the clothes.
4. Add your usual laundry detergent to its dispenser.
5. Wash on a normal cycle with warm water. The baking soda will neutralize odors during the wash.

Pro-Tip: For persistent pet odors or deep-set smells, combining baking soda with a cup of white vinegar in the rinse cycle can create a powerful deodorizing duo. The baking soda and vinegar react to release gases that lift and eliminate odors, leaving items extra fresh.

3. Whiten and Brighten White Clothes Naturally

Achieve brilliant whites—save this eco-friendly trick!

Over time, white fabrics can become dingy or develop a dull yellowing due to residue buildup. Baking soda serves as a gentle yet effective bleach alternative to whiten white clothes and restore their brilliance. It helps lift grime and break down mineral deposits from hard water that can cause discoloration. As a natural way to whiten clothes, it’s much gentler on fabrics than chlorine bleach and is a fantastic non-toxic option for keeping your bright whites looking their best.

Supplies Needed

• 1/2 cup baking soda
• Your preferred laundry detergent
• Optional: white vinegar for extra boost

Quick Steps

1. Add your white clothes to the washing machine drum.
2. Sprinkle 1/2 cup of baking soda directly over the clothes or into the detergent dispenser.
3. Add your usual amount of laundry detergent.
4. Wash on the hottest cycle recommended for your fabric type. Hot water helps to activate the baking soda‘s whitening properties.
5. For extra whitening power: In the rinse cycle, add 1/2 cup of white vinegar to the fabric softener dispenser. Do NOT mix baking soda and vinegar directly in the same dispenser or at the same time in the wash cycle, as they will neutralize each other.

Pro-Tip: For severely dingy whites or specific yellowing spots, create a thick paste of baking soda and a little water. Apply it directly to the problem areas, let it sit for an hour, then scrub gently before washing as usual. This can also help with some types of stubborn stains.

4. Soften Fabrics Naturally Without Commercial Softeners

Get luxuriously soft clothes the natural way!

Commercial fabric softeners work by coating fibers with chemicals, which can reduce towel absorbency and irritate sensitive skin. Baking soda is an excellent fabric softener alternative that works by preventing mineral and detergent residue from redepositing on your clothes. This residue is a primary cause of stiff fabrics. By helping to rinse it away, baking soda allows clothes to emerge from the wash naturally soft and fluffy, without any waxy buildup. It’s a perfect chemical-free way to soften clothes naturally.

Supplies Needed

• 1/2 cup baking soda
• Your regular laundry detergent

Quick Steps

1. Add your clothes to the washing machine.
2. Sprinkle 1/2 cup of baking soda directly into the drum at the start of the wash cycle.
3. Add your usual laundry detergent to its dispenser.
4. Run your preferred wash cycle. The baking soda helps to soften the water and rinse away detergent residue, which is a common cause of stiff fabrics.

Pro-Tip: For an enhanced softening effect, particularly on towels or jeans, consider adding 1/2 cup of white vinegar to the rinse cycle (the fabric softener dispenser). The slight acidity of the vinegar works synergistically with the baking soda to leave fabrics feeling exceptionally soft and free from detergent residue, without leaving a vinegar smell.

5. Tackle Stubborn Stains with Targeted Baking Soda Treatments

Your secret weapon against stains! Pin this guide!

For many stubborn stains, a baking soda paste can be a powerful pre-treatment. The mild abrasive quality of baking soda helps to gently scrub away stains without damaging fibers. When made into a paste, it can pre-treat stains like oil, grease, and food spills by helping to absorb and lift the staining agent from the fabric. This stain-fighting ability makes it a go-to natural stain remover for your laundry room.

Supplies Needed

• Arm & Hammer Pure Baking Soda
• Water
• Optional: Hydrogen Peroxide (for tough or colored stains), small brush
• Your regular laundry detergent

Quick Steps

1. Create a Paste: In a small bowl, mix 2 parts baking soda with 1 part water (or hydrogen peroxide for colored stains like wine or grass) until a thick paste forms.
2. Apply to Stain: Sprinkle a generous amount of the paste directly onto the stubborn stain. For extra effectiveness, gently scrub the paste into the fabric using a soft brush or your fingers.
3. Let Sit: Allow the paste to sit on the stain for at least 30 minutes, or up to several hours for very tough stains like grease stains or ground-in dirt. The baking soda will help to dissolve and lift the stain.
4. Wash: After the paste has worked its magic, rinse off any excess and then wash the garment as usual with your regular laundry detergent on the hottest recommended temperature.

Pro-Tip: Always test the baking soda paste on an inconspicuous area of the fabric first, especially if using hydrogen peroxide or on delicate items, to ensure fabric safety guide and prevent discoloration. This method is particularly effective for oil-based grease stains and protein-based stains when acted upon quickly.

6. Keep Your Washing Machine Clean and Fresh

Don’t forget your machine! Clean your washer the baking soda way.

A clean washing machine is the first step to clean laundry. Over time, soap scum, mineral deposits, and mildew can build up inside your washer, leading to a mildew smell washer and less effective cleaning. A monthly cleaning cycle with baking soda and vinegar can clean washing machine parts, remove hard water buildup, and act as an odor eliminator, ensuring your machine stays fresh and runs efficiently.

Supplies Needed

• 1/2 cup baking soda
• 2 cups white vinegar
• Empty washing machine

Quick Steps

1. Add Baking Soda: Sprinkle 1/2 cup of baking soda directly into the detergent dispenser of your washing machine.
2. Add Vinegar: Pour 2 cups of white vinegar directly into the washing machine drum (do not combine with baking soda in the dispenser as they will fizz and neutralize).
3. Run Hot Cycle: Run the washing machine on its hottest water setting and longest cycle. If your machine has a “Clean Washer” or “Self-Clean” cycle, use that.
4. Wipe Down: Once the cycle is complete, wipe down the inside of the drum, gasket (for front-loaders), and dispensers with a damp cloth to remove any loosened grime or mildew.
5. Leave Door Ajar: After cleaning, leave the machine door slightly ajar to allow the interior to air dry, preventing future moldy smell and mildew growth.

Pro-Tip: Regular cleaning of your washing machine is crucial for preventing detergent residue buildup, eliminating moldy smell, and ensuring efficient operation. For HE washers, using baking soda and vinegar is a HE-compatible and environmentally safe solution, but always consult your machine manufacturer guidelines for specific cleaning instructions.

7. DIY Laundry Detergent with Baking Soda for a Natural Clean

FAQs About baking soda laundry detergent

Can I use baking soda instead of laundry detergent?

While baking soda is an excellent laundry booster and deodorizer, it is not a complete laundry detergent replacement. It excels at neutralizing odors, softening water, and boosting cleaning power, but it lacks the surfactants and enzymes found in traditional detergents that are crucial for effectively breaking down and lifting oils, dirt, and stubborn stains from fabrics. It is best used as an additive.

How much baking soda should I add to laundry?

For most standard loads, 1/2 cup of baking soda is sufficient. For heavily soiled items, extra-large loads, or clothes with strong odors like gym clothes or sour towels, you can increase the amount to 1 full cup. Always add baking soda directly to the drum or detergent dispenser, not the fabric softener compartment.

Does baking soda damage washing machines?

No, baking soda is generally safe for washing machines, including HE models. Its non-abrasive nature and ability to dissolve means it won’t scratch or corrode machine parts. In fact, using baking soda regularly can help clean your machine, prevent mildew smell, and reduce hard water buildup, contributing to its longevity.

Can you mix baking soda and vinegar in laundry?

Yes, but you should not mix them directly together in the same dispenser or at the same time in the wash cycle. They react to neutralize each other, reducing their individual effectiveness. Instead, add baking soda at the start of the wash cycle with your detergent, and add white vinegar during the rinse cycle as a natural fabric softener and deodorizer.

Is baking soda safe for HE washers?

Baking soda primarily acts as an odor neutralizer, detergent booster, and fabric softener for clothes. It raises the water’s pH, which helps laundry detergent work more effectively, reduces hard water buildup, and gently brightens fabrics. It can also help loosen dirt and act as a mild abrasive for stubborn stains.

Can baking soda replace fabric softener?

Baking soda can serve as an excellent natural alternative to commercial fabric softeners. It helps to soften clothes by neutralizing odors and rinsing away detergent residue that can make fabrics feel stiff. For enhanced softening, it works particularly well when combined with white vinegar in the rinse cycle.

How to use baking soda for smelly clothes?

To use baking soda for smelly clothes, you can either pre-soak or add it directly to the wash. For tough odors, dissolve 1 cup of baking soda in warm water and soak garments for 30 minutes to overnight. Alternatively, sprinkle 1/2 to 1 cup of baking soda into the drum with your clothes before starting the wash cycle.

Does baking soda whiten white clothes?

Yes, baking soda effectively whitens and brightens white clothes naturally. It helps to lift grime and reduce yellowing or dinginess without harsh chemicals like chlorine bleach. For best results, use it consistently and consider adding hydrogen peroxide or white vinegar (in separate cycles) for an extra boost.

Is baking soda safe for baby clothes?

Yes, baking soda is generally considered safe for baby clothes due to its gentle, non-toxic, and fragrance-free nature. It can be especially beneficial for sensitive baby skin. Always ensure it’s fully dissolved and rinsed out to prevent any residue, just as you would with any laundry detergent.
