How to Put Baking Soda in the Fridge? Effectively Eliminating Odors
Baking soda neutralizes odors by absorbing acidic and alkaline molecules, making it an effective and inexpensive way to keep your refrigerator smelling fresh. For optimal use, place an open box or container of baking soda in the back of your refrigerator.
Understanding Fridge Odors and Why Baking Soda Works
The unpleasant smells that plague refrigerators are often caused by the breakdown of food, spills, and trapped moisture. These processes release volatile organic compounds (VOCs), many of which have distinct and often offensive odors. Unlike air fresheners that simply mask these smells, baking soda (sodium bicarbonate) works by neutralizing them. It’s a chemical compound with the ability to react with both acidic and alkaline odor molecules, effectively binding to them and preventing them from becoming airborne.
The Benefits of Using Baking Soda in Your Fridge
Using baking soda is a simple, budget-friendly, and safe way to combat fridge odors.
- Odor Neutralization: Eliminates, rather than masks, unpleasant smells.
- Cost-Effective: Far cheaper than commercial fridge deodorizers.
- Non-Toxic: Safe for use around food and children.
- Simple to Use: Requires minimal effort to set up and maintain.
- Versatile: Can also be used in freezers and other areas prone to odors.
Step-by-Step Guide: Placing Baking Soda in Your Fridge
Follow these simple steps to effectively utilize baking soda in your refrigerator:
- Choose Your Container: You can use the original baking soda box (opened), a dedicated open container, or a jar with a breathable lid (e.g., cheesecloth secured with a rubber band).
- Prepare the Baking Soda: If using a new box, tear off the perforated section on the side. If using a container, simply pour in a fresh supply of baking soda.
- Placement is Key: Place the open container of baking soda in the back of your refrigerator, away from the door. This area typically has the most consistent temperature and is less susceptible to temperature fluctuations caused by opening and closing the door.
- Monitor and Replace: Replace the baking soda every month or two. You’ll know it’s time when you start noticing odors returning.
Optimizing Baking Soda’s Effectiveness
Several factors can influence how well baking soda works in your fridge:
- Surface Area: The larger the surface area of the baking soda exposed to the air, the more effectively it will absorb odors. Using a shallow, wide container maximizes surface area.
- Airflow: Ensure good airflow around the container of baking soda. Avoid overcrowding your fridge with food, which can restrict air circulation.
- Regular Replacement: As baking soda absorbs odors, its effectiveness decreases. Replace it regularly to maintain optimal performance.
- Quantity: While a single box or container is generally sufficient, larger refrigerators or fridges with persistent odor problems may benefit from multiple containers.
Common Mistakes to Avoid
- Using an Unopened Box: This defeats the purpose entirely! The baking soda must be exposed to the air.
- Placing it Near Food: While baking soda is safe, avoid placing it directly next to uncovered food to prevent accidental contamination.
- Forgetting to Replace It: Baking soda doesn’t last forever. Set a reminder to replace it regularly.
- Ignoring the Source of the Odor: Baking soda helps neutralize odors, but it won’t eliminate the underlying cause. Clean up spills and dispose of spoiled food promptly.
- Using Baking Powder Instead of Baking Soda: They are not interchangeable. Baking powder contains baking soda plus an acidifying agent and will not work the same way.
Alternative Uses for Used Baking Soda
Don’t throw away the used baking soda! It can still be used for other purposes:
- Cleaning: Use it to scrub sinks, countertops, and stovetops.
- Drains: Pour it down drains with hot water to help freshen them.
- Composting: Add it to your compost pile to help neutralize acidity.
Baking Soda vs. Commercial Fridge Deodorizers
While commercial fridge deodorizers often contain activated charcoal or other odor-absorbing agents, baking soda remains a compelling option due to its cost-effectiveness and simplicity.
| Feature | Baking Soda | Commercial Fridge Deodorizers |
|---|---|---|
| Cost | Very inexpensive | More expensive |
| Effectiveness | Effective for general odor control | Can be more effective for stronger odors |
| Safety | Non-toxic and safe for use around food | May contain chemicals, check product label |
| Maintenance | Requires monthly or bi-monthly replacement | Varies depending on the product |
| Environmental Impact | Biodegradable and environmentally friendly | May contribute to landfill waste |
Frequently Asked Questions (FAQs)
How long does baking soda last in the fridge?
Baking soda typically remains effective for one to two months in the refrigerator. After this time, its odor-absorbing capacity diminishes, and you should replace it with fresh baking soda. Setting a calendar reminder can help you remember to change it regularly.
Can I use a closed box of baking soda in the fridge?
No, a closed box of baking soda will not absorb odors. The baking soda needs to be exposed to the air in order to neutralize the volatile compounds causing the smells. Make sure the box is properly opened before placing it in your refrigerator.
What happens if I accidentally eat baking soda that was in the fridge?
Eating a small amount of baking soda is generally not harmful, but consuming larger quantities can cause digestive upset. It’s best to avoid eating baking soda that has been sitting in the fridge, but a tiny amount consumed accidentally shouldn’t be a cause for serious concern.
Does baking soda expire?
While baking soda itself doesn’t truly “expire,” its odor-absorbing effectiveness decreases over time, especially after it has been opened. Store unused baking soda in a cool, dry place to maintain its potency. For optimal use in the fridge, it should be replaced regularly, even if it seems like there’s still a lot left in the container.
Can I use baking soda in the freezer?
Yes, baking soda works just as well in the freezer as it does in the refrigerator. The cold temperatures can sometimes trap odors, making baking soda even more valuable in this environment. Follow the same placement and replacement guidelines as for your fridge.
My fridge still smells bad even with baking soda. What else can I do?
Baking soda is just one part of maintaining a fresh-smelling fridge. Thoroughly clean your refrigerator regularly, removing all food items and wiping down surfaces. Check for expired or spoiled food and discard it immediately. Consider using a commercial fridge cleaner for stubborn odors.
Is there a better alternative to baking soda for fridge deodorizing?
While baking soda is a great option, activated charcoal is another popular and effective choice. It has a larger surface area than baking soda and may be more effective at absorbing stronger odors. However, it is typically more expensive than baking soda.
Can I reuse the baking soda after it’s been in the fridge?
Yes, but not for baking. Once the baking soda has absorbed odors in the fridge, it’s no longer suitable for baking purposes. However, you can reuse it for cleaning or deodorizing other areas, as mentioned earlier.
Will baking soda change the taste of my food?
No, baking soda will not change the taste of your food, as long as it’s contained in an open container and not directly touching any food items. It only absorbs odors, it does not emit anything that would alter the taste of your food.
Where is the best place to buy baking soda?
Baking soda is widely available in most grocery stores and pharmacies. It’s typically found in the baking aisle. Buying in bulk can save you money if you plan to use it regularly for fridge deodorizing and other purposes.
Can I mix baking soda with other ingredients for better odor absorption?
While you can find recipes suggesting adding ingredients like lemon juice or vinegar to baking soda for enhanced cleaning, it’s not recommended for fridge deodorizing. The mixing will cause a reaction, using up the baking soda before it can neutralize the odors.
How often should I clean my fridge?
Ideally, you should clean your refrigerator at least once a month. This involves removing all food items, wiping down shelves and drawers, and discarding any expired or spoiled food. Regular cleaning, combined with the use of baking soda, will keep your fridge smelling fresh and clean.
