Salt as Laundry Booster: Benefits, Uses, and Tips

July 25, 2025 by RubyHome tricks

Salt as Laundry Booster: Prepare to unlock a laundry secret that’s been hiding in plain sight! Forget those expensive, chemical-laden detergents and fabric softeners. I’m about to share a simple, yet incredibly effective, DIY trick using something you probably already have in your kitchen: salt!

For centuries, salt has been valued not just for its culinary uses, but also for its cleaning and preserving properties. Think about it – our ancestors used salt to cure meats and keep fabrics fresh long before the invention of washing machines. This knowledge, passed down through generations, highlights the power of natural solutions.

In today’s world, we’re constantly bombarded with products promising brighter whites and softer clothes. But many of these contain harsh chemicals that can irritate skin, damage fabrics, and harm the environment. That’s where this DIY hack comes in. Using salt as laundry booster is a cost-effective, eco-friendly, and surprisingly powerful way to enhance your laundry routine. I’ll show you how to use it to brighten whites, prevent colors from fading, and even tackle stubborn stains. Get ready to say goodbye to dull, lifeless laundry and hello to fresh, vibrant clothes – all thanks to the humble power of salt!

DIY Laundry Booster: Unleash the Power of Salt!

Hey there, fellow laundry enthusiasts! Are you tired of dull whites and faded colors? Do you wish your clothes could just *pop* a little more? Well, I’ve got a secret weapon for you: good old table salt! Yes, you read that right. Salt isn’t just for seasoning your food; it’s a fantastic, inexpensive laundry booster that can seriously up your laundry game. I’m going to walk you through exactly how to use it.

Why Salt? The Science Behind the Sparkle

Before we dive into the how-to, let’s talk about why salt works so well. Salt, specifically sodium chloride, has several properties that make it a laundry superstar:

* Color Brightener: Salt acts as a mordant, helping to set colors and prevent them from bleeding or fading during washing. Think of it as a color bodyguard!
* Stain Remover: Salt can help loosen certain stains, especially those caused by mildew or sweat. It’s not a miracle worker on every stain, but it’s a great first line of defense.
* Mildew Fighter: Salt inhibits the growth of mildew, which is especially helpful in damp climates or if you sometimes leave wet clothes in the washing machine (we’ve all been there!).
* Water Softener: In hard water areas, salt can help soften the water, allowing your detergent to work more effectively. This means cleaner clothes with less detergent!
* Prevents Yellowing: Salt can help prevent white clothes from yellowing over time, keeping them looking fresh and bright.

What You’ll Need

This is a super simple DIY, so you probably already have everything you need:

* Table salt (iodized or non-iodized, it doesn’t matter)
* Your regular laundry detergent
* Your washing machine
* A measuring cup or spoon

Using Salt as a Laundry Booster: Step-by-Step

Okay, let’s get down to business! Here’s how to use salt to boost your laundry’s cleaning power:

1. Sort Your Laundry: As always, start by sorting your laundry into whites, lights, and darks. This is crucial to prevent color bleeding, even with the salt’s help.
2. Load Your Washing Machine: Place your sorted laundry into the washing machine. Don’t overload it; clothes need room to move around for proper cleaning.
3. Add Detergent: Add your regular laundry detergent according to the manufacturer’s instructions. I usually use a little less detergent when I’m using salt, as the salt helps boost its effectiveness.
4. Add Salt: This is the magic step! Add 1/2 cup of salt to the washing machine drum. You can add it directly to the drum with the clothes, or you can add it to the detergent dispenser if your machine has one. I usually just toss it in with the clothes.
5. Start the Wash Cycle: Select your desired wash cycle and water temperature. For colors, I recommend using cold water to further prevent fading. For whites, you can use warm or hot water.
6. Dry Your Clothes: Once the wash cycle is complete, dry your clothes as usual. You can tumble dry them or hang them out to dry.

Specific Laundry Situations: Salt’s Superpowers Unleashed

Now, let’s talk about some specific laundry situations where salt can really shine:

Brightening Whites

Do your white shirts look a little dingy? Salt to the rescue!

1. Pre-Soak (Optional): For extra brightening power, you can pre-soak your white clothes in a solution of warm water and 1/2 cup of salt for about 30 minutes before washing.
2. Wash as Usual: Follow the steps above, using warm or hot water for the wash cycle.
3. Check for Results: After washing, check your whites to see if they’re brighter. If they’re still not as bright as you’d like, you can repeat the process.

Preventing Color Bleeding

Worried about that new red shirt bleeding onto your other clothes? Salt can help!

1. First Wash is Key: The first time you wash a new, brightly colored garment, it’s especially important to use salt.
2. Cold Water is Your Friend: Always wash new, brightly colored clothes in cold water to minimize color bleeding.
3. Add Salt: Add 1/2 cup of salt to the wash cycle.
4. Wash Separately (If Necessary): If you’re really concerned about color bleeding, you can wash the new garment separately for the first few washes.

Tackling Mildew Smells

Did you accidentally leave wet clothes in the washing machine for too long? Don’t worry, salt can help get rid of that mildew smell!

1. Re-Wash Immediately: As soon as you realize you’ve left wet clothes in the machine, re-wash them immediately.
2. Hot Water is Essential: Use hot water for the wash cycle to kill the mildew.
3. Add Salt and Vinegar: Add 1/2 cup of salt and 1/2 cup of white vinegar to the wash cycle. Vinegar is another great natural laundry booster that helps eliminate odors.
4. Dry Thoroughly: Make sure to dry your clothes thoroughly after washing to prevent the mildew from returning.

Dealing with Stains

While salt isn’t a miracle stain remover, it can help loosen certain stains, especially those caused by sweat or mildew.

1. Pre-Treat the Stain: Before washing, pre-treat the stain with a paste made from salt and water.
2. Apply the Paste: Apply the paste to the stain and let it sit for about 30 minutes.
3. Wash as Usual: Wash the garment as usual, adding 1/2 cup of salt to the wash cycle.

Important Considerations

While salt is generally safe to use in laundry, there are a few things to keep in mind:

* Test on Delicate Fabrics: If you’re washing delicate fabrics, such as silk or lace, it’s always a good idea to test the salt on a small, inconspicuous area first to make sure it doesn’t damage the fabric.
* Don’t Overdo It: Using too much salt can actually damage your clothes or your washing machine. Stick to the recommended amount of 1/2 cup per load.
* Check Your Washing Machine’s Manual: Some washing machines have specific instructions regarding the use of additives like salt. Be sure to check your machine’s manual before using salt.
* Not a Substitute for Detergent: Salt is a laundry booster, not a substitute for detergent. You still need to use detergent to properly clean your clothes.

My Personal Experience

I’ve been using salt as a laundry booster for years, and I’ve been consistently impressed with the results. My whites are brighter, my colors are more vibrant, and my clothes smell fresher. Plus, it’s such an inexpensive and easy way to improve my laundry routine! I especially love using it on my kids’ clothes, which tend to get stained and dirty very quickly. It really helps to keep them looking their best.

I hope you give this DIY laundry booster a try! I’m confident that you’ll be amazed at the difference it can make. Happy washing!

Conclusion

So, there you have it! Transforming your laundry routine with the simple addition of salt is not just a cost-effective hack; it’s a game-changer for brighter whites, vibrant colors, and a fresher overall clean. We’ve explored how salt acts as a natural color sealant, preventing dye from bleeding and fading, and how its mild abrasive properties help to lift stubborn stains without harsh chemicals. Beyond stain removal and color preservation, salt also works wonders in softening fabrics and reducing mildew buildup in your washing machine.

This DIY trick is a must-try because it’s accessible, affordable, and environmentally friendly. You likely already have salt in your pantry, eliminating the need to purchase expensive and potentially harmful commercial laundry boosters. By incorporating salt into your laundry routine, you’re not only saving money but also reducing your environmental footprint.

But the benefits don’t stop there! Feel free to experiment with different types of salt to see what works best for your laundry needs. Coarse sea salt can be particularly effective for stain removal, while Epsom salt (magnesium sulfate) adds an extra softening boost. You can also enhance the scent of your laundry by adding a few drops of essential oil, such as lavender or lemon, to the salt before adding it to the washing machine. For heavily soiled items, consider pre-soaking them in a salt water solution before washing.

Don’t just take our word for it – try this simple yet effective laundry booster yourself! We’re confident that you’ll be amazed by the results. From brighter whites to more vibrant colors and a fresher, cleaner scent, salt can truly transform your laundry experience.

We encourage you to experiment with different amounts of salt and various types of fabrics to find the perfect balance for your needs. Remember to always test a small, inconspicuous area of the fabric first to ensure colorfastness, especially with delicate or brightly colored items.

Frequently Asked Questions (FAQs)

1. How much salt should I add to my laundry?

The amount of salt you add to your laundry depends on the size of your load and the type of washing machine you have. As a general guideline, we recommend adding about ½ cup of salt to a standard-sized load of laundry. For larger loads, you can increase the amount to ¾ cup or even 1 cup. If you have a high-efficiency (HE) washing machine, you may need to reduce the amount of salt slightly to prevent oversudsing. Start with ¼ cup and adjust as needed. Remember, it’s always best to err on the side of caution and start with less salt, as you can always add more if needed.

2. What type of salt is best for laundry?

While regular table salt works perfectly well for most laundry purposes, you can also experiment with other types of salt to see what works best for you. Coarse sea salt can be particularly effective for stain removal due to its slightly abrasive texture. Epsom salt (magnesium sulfate) is a great option for softening fabrics and reducing static cling. Kosher salt is another good choice, as it dissolves easily and doesn’t contain any additives that could potentially harm your clothes. Avoid using iodized salt, as the iodine can sometimes stain fabrics.

3. Can I use salt on all types of fabrics?

In most cases, salt is safe to use on all types of fabrics. However, it’s always a good idea to test a small, inconspicuous area of the fabric first to ensure colorfastness, especially with delicate or brightly colored items. Avoid using salt on fabrics that are known to be sensitive to salt, such as silk or wool. If you’re unsure, consult the care label on the garment or test a small area before washing the entire item.

4. Will salt damage my washing machine?

No, salt will not damage your washing machine. In fact, salt can actually help to prevent mildew buildup in your washing machine by absorbing excess moisture. However, it’s important to use the correct amount of salt and to avoid using too much, as this could potentially clog the drain. Always follow the manufacturer’s instructions for your washing machine and use the appropriate amount of detergent and salt.

5. Can salt remove all types of stains?

While salt is effective at removing many types of stains, it may not be able to remove all stains completely. Salt works best on fresh stains, such as blood, grass, and ink. For older or more stubborn stains, you may need to pre-treat the stain with a stain remover before washing the item with salt. You can also try making a paste of salt and water and applying it directly to the stain. Let the paste sit for a few minutes before rinsing and washing the item as usual.

6. Can I use salt in combination with other laundry boosters?

Yes, you can use salt in combination with other laundry boosters, such as baking soda or vinegar. Baking soda can help to brighten whites and neutralize odors, while vinegar can help to soften fabrics and remove soap residue. When using salt in combination with other laundry boosters, be sure to use the correct amounts of each ingredient and to avoid using too much, as this could potentially damage your clothes or your washing machine.

7. How does salt help to prevent colors from fading?

Salt acts as a natural color sealant by helping to lock the dye into the fabric fibers. This prevents the dye from bleeding and fading during the wash cycle, keeping your clothes looking vibrant and new for longer. To maximize the color-preserving benefits of salt, add it to the wash during the first few washes of a new garment.

8. Can I use salt to freshen up my laundry?

Yes, salt can help to freshen up your laundry by absorbing odors and preventing mildew buildup. To freshen up your laundry with salt, add ½ cup of salt to the wash cycle along with your regular detergent. You can also add a few drops of essential oil, such as lavender or lemon, to the salt before adding it to the washing machine for an extra boost of freshness.

9. What if I don’t see a noticeable difference after using salt in my laundry?

The effectiveness of salt as a laundry booster can vary depending on the type of fabric, the severity of the stains, and the type of washing machine you have. If you don’t see a noticeable difference after using salt in your laundry, try increasing the amount of salt you use or pre-treating stains with a salt water paste. You can also try using a different type of salt, such as coarse sea salt or Epsom salt. If you’re still not satisfied with the results, you may need to consider using a stronger laundry booster or stain remover.

10. Is using salt in laundry safe for septic systems?

Yes, using salt in your laundry is generally considered safe for septic systems. Salt is a natural mineral and does not contain any harsh chemicals that could harm the bacteria in your septic tank. However, it’s important to use the correct amount of salt and to avoid using too much, as this could potentially overload your septic system. If you have any concerns about using salt in your laundry with a septic system, consult with a septic system professional.
