Does Baking Soda Damage Washing Machines? The Whole Truth Explained
Baking soda, a common household staple, is well-known for its cleaning, deodorizing, and stain-removing abilities. When it comes to laundry, many people use baking soda to freshen clothes, boost detergent performance, and even clean their washing machines themselves. But is this popular advice really safe for your washing machine? Let’s get to the bottom of whether baking soda can cause damage—and how to use it safely if you decide to give it a try.
Is Baking Soda Safe for Your Washing Machine?
In short, using baking soda in your washing machine is generally safe and unlikely to cause damage when used correctly and in moderation. Many appliance experts, cleaning professionals, and experienced home-keepers recommend using baking soda as an occasional laundry booster or cleaning agent.
However, like anything else, too much of a good thing can backfire. Excessive or improper use of baking soda could, over time, lead to certain issues in both high-efficiency (HE) and traditional washing machines. That’s why it’s essential to know how to use baking soda wisely for the best results—and to protect your appliance.
Why Do People Use Baking Soda in Laundry?
Before diving into the nitty-gritty, it helps to understand what makes baking soda such a go-to for laundry routines:
- Odor Removal: Baking soda neutralizes acidic odors and freshens both clothes and the washing machine.
- Detergent Booster: It helps soften water slightly, allowing detergent to work more effectively.
- Stain Removal: It can gently help lift stains from fabrics.
- Cleaning Agent: Many use it to clean residue and reduce musty smells in the drum.
How Baking Soda Affects Washing Machines
The Science in Simple Terms
- Baking soda (sodium bicarbonate) is mildly alkaline but not corrosive.
- It dissolves easily in water.
- Used sparingly, it does not harm metal, plastic, or rubber components found in modern washing machines.
Potential Benefits
- Residue Reduction: Baking soda can tackle detergent build-up, leaving the drum and internal hoses cleaner.
- Fresh-Smelling Machine: It helps eliminate damp or musty odors that sometimes linger, especially in front loaders.
- Gentle Cleaning: Unlike harsh chemicals, baking soda cleans without leaving scratches or corroding surfaces.
Possible Challenges and Risks
Even though baking soda is safe for the vast majority of machines, it’s important to be aware of a few caveats:
- Excessive Use: Overuse, especially in every cycle or in large amounts, can occasionally cause undissolved powder to accumulate in hose lines or dispensers.
- Mixing with Vinegar: While baking soda and vinegar are often paired together, they neutralize each other. When mixed inside the machine, their combined action is less effective than when used separately.
- Rinse Quality: If not fully dissolved, baking soda can leave a film or residue on clothing and inside the machine.
How to Safely Use Baking Soda in Your Washing Machine
Using baking soda safely is straightforward. The key is moderation and proper technique.
Steps for Using Baking Soda in Laundry
- Add to the Drum: Sprinkle up to half a cup of baking soda directly into the empty drum before adding clothes.
- Add Detergent: Add your usual detergent as you normally would.
- Choose the Cycle: Run your preferred wash cycle as usual.
- For Cleaning: To clean the machine itself, add baking soda (about half a cup) to the drum and run an empty hot water cycle.
Tips for Best Results
- Don’t Use Excessively: Once or twice a month is plenty for machine cleaning; use smaller amounts (1/4 to 1/2 cup) in laundry as needed.
- Don’t Overfill the Dispenser: Only use baking soda in the dispenser if your machine’s manufacturer states it’s safe—otherwise, stick to adding it in the drum.
- Avoid with Bleach: Never mix baking soda with bleach during the wash; stick to detergent and baking soda if you choose to combine.
- Run an Extra Rinse: If you notice residue, an extra rinse cycle can help.
Best Practices for Cleaning Your Washing Machine with Baking Soda
Regular cleaning keeps your machine running efficiently and odor-free. Here’s how you can do it:
- Monthly Cleanse:
- Add half a cup of baking soda to the drum.
- Run a hot, empty cycle.
-
Wipe down the drum and seals after the cycle for a spotless finish.
-
For Tough Odors:
- Add half a cup of baking soda and (in a separate cycle) a cup of white vinegar, running the machine empty each time.
-
Do not mix both together in the same cycle to ensure maximum effectiveness.
-
Detergent Dispenser Care:
-
Occasionally remove and wash the detergent drawer with a baking soda paste and warm water.
-
Door Seals & Gaskets:
- Use a damp cloth and a little baking soda to gently scrub rubber gaskets, where grime and mildew gather.
Does Baking Soda Work for Both Front and Top Loaders?
Good news: Baking soda is suitable for use in both front and top-loading washing machines.
- Front Loaders: Since front load machines can retain moisture and develop mildew smells, baking soda is especially helpful here.
- Top Loaders: It works equally well to freshen the drum and boost cleaning.
Just remember that modern machines, especially those labeled as “High Efficiency,” require low-sudsing agents. Baking soda fits this requirement when used in moderation.
When to Avoid Using Baking Soda
While safe in most situations, there are a few times you might want to skip the baking soda:
- If Your Manufacturer Says No: Always check your washing machine’s manual. If there are restrictions, follow them closely.
- If You Have Septic Systems: Baking soda is usually septic-safe, but overly frequent use of any additives can disrupt the balance.
- If Clothes Are Especially Delicate: Most fabrics tolerate baking soda, but delicate items should always be treated according to care labels.
Myths and Misconceptions
Let’s address a few misconceptions about baking soda and washing machines:
- “Baking soda will corrode my machine.”
False! Baking soda is gentle, not corrosive, and won’t react with plastic or metal parts. - “It will clog pipes and hoses.”
Only if used to excess and not properly dissolved—stick to the right amount, and you’re safe. - “It replaces detergent entirely.”
Baking soda is a great booster, not a full replacement for quality laundry detergent.
Practical Advice to Get the Most Out of Baking Soda in Laundry
- Store Correctly: Keep baking soda in a cool, dry place so it doesn’t clump before use.
- Check for Dissolving: Use warm water cycles to help baking soda dissolve if you have hard water.
- Pair with Vinegar (Separately): Use baking soda and vinegar in separate cycles for deep cleaning, not together at the same time.
Concluding Thoughts
When used correctly, baking soda is a safe, inexpensive, and effective addition to your laundry routine—and it won’t harm your washing machine. Limit usage to occasional doses, follow the right steps, and your washer (and laundry) will benefit from this household hero. As with any cleaning habit, moderation and attention to manufacturer guidance are key for keeping your appliance in top condition.
Frequently Asked Questions (FAQs)
1. Will baking soda corrode the parts inside my washing machine?
No, baking soda is mild and non-corrosive. Used in small to moderate amounts, it won’t harm metal, plastic, or rubber parts inside your washing machine.
2. How much baking soda should I use in a wash cycle?
A quarter to half a cup is plenty for boosting your laundry. Avoid using more, as it won’t improve cleaning and might leave behind residue.
3. Can I use baking soda in every laundry load?
It’s unnecessary to use it in every load. Occasional use is best for both laundry and machine cleaning to avoid build-up in hoses or dispensers.
4. Is it safe to combine baking soda and vinegar in my washing machine?
You can use both, but not at the same time. For a thorough clean, run a cycle with baking soda, followed by another with vinegar. Mixing them neutralizes their effects.
5. Will baking soda fade or damage colored fabrics?
Baking soda is generally safe for colored laundry when used in small amounts. However, always check garment care instructions and try a test with especially delicate or new colored items.
With these tips, you can safely harness the cleaning power of baking soda without worrying about your washing machine’s longevity or performance. Happy washing!
