Baking Soda Alone Received’t Repair Your Funky Fridge Odor—Right here’s What Really Works

A reader letter implored us for assist on the planet of bizarre fridge smells. The word had extra questions than a Dr. Seuss ebook, and I cherished it. I am additionally so happy by the truth that this particular person went proper from “secret compartment” to “haunted.” They had been clearly raised proper:

I’ve a fairly historic fridge that, about six months in the past, began emanating a barely gross, funky odor each time I would open the fridge door. As luck would have it, we misplaced energy a few months in the past, offering me with a superb alternative to scrub out the fridge and freezer, toss outdated/questionable meals, and clear all of the cabinets and drawers. However, every week later, I began noticing the scent once more. WHAT COULD IT BE!? Is there some secret compartment I am lacking and forgetting to scrub? Is the fridge simply outdated and nasty? Is it haunted? I’ve tried leaving a bowl of baking soda inside to soak up odors, however no cube. Ought to I simply get a brand new fridge?

Let’s dive in.

What Causes Fridge Odors?

Earlier than we get into the nitty-gritty, let’s check out the how and why of this explicit drawback. The sorts of odors which can be plaguing your fridge are brought on by molecules of what we’ll name “stuff,” that are emitted out of your meals and float within the air, circulating in that small, enclosed area. If you open the door, these molecules enter your nostril and set off receptors that make you say “ew.” If it helps, you may think about these offending odor molecules as ships, aimlessly wandering the ocean of your fridge, searching for a port. By default, the sleek partitions of a fridge cannot maintain many ships, however your nostril, filled with receptors, makes an excellent port. Your aim right here? Present a spot for these boats to dock earlier than they make it to your nostril.

Conserving Odors at Bay

On the brilliant facet, you’ve got already carried out the very first thing I’d have steered—you’ve got completely inventoried and cleaned the within of your fridge. And, fortunately, you’ve got additionally stumbled into asking precisely the precise query: There IS a secret compartment in most fridges. It is known as the drip pan, and it is simply what it seems like—a pan to catch drips. However, as you may think, it could actually additionally catch greater than drips, resulting in a pool of foul-smelling water over time. The drip pan may be very doubtless the supply of your scent state of affairs.

The pan shall be positioned underneath your fridge, and, relying on the mannequin, you will both entry it from the entrance (behind a kick plate), otherwise you’ll have to drag out the fridge to entry it from the again. (Examine your guide, or discover it on-line by looking for the model and mannequin quantity.) As soon as you’ve got eliminated it, clear it with a sponge or rag and dish cleaning soap, all-purpose cleaner, or bleach resolution.

After you’ve got eliminated, cleaned, and changed the drip pan, the odor ought to noticeably enhance. That stated, there should still be a lingering scent, and, after all, you will need to preserve new odors from creating. Which implies you’ve got additionally given me an ideal excuse to speak about the easiest way to maintain low-level fridge smells at bay—one thing virtually everybody has to take care of sooner or later in his or her grownup life.

Typically talking, there are two fundamental techniques we will deploy to unravel a persistent odor drawback. We are able to attempt to drown it out by introducing different molecules of a much less offensive nature—we’ll name these the deodorants of the cleansing world. Or, we will attempt to take them out of circulation fully, by offering different locations for them to dock—our antiperspirants.

How Deodorants Work

The previous methodology could be low-cost, straightforward, and comparatively efficient, nevertheless it comes with a couple of caveats. That is as a result of, like deodorant, these merchandise (particularly, espresso grounds, white vinegar, and gel odor eliminators) emit smells of their very own. Odor is a really subjective factor, so I can not say whether or not you’d get pleasure from getting a whiff of, say, espresso each time you attain into the fridge for a carton of orange juice. However, even when that does sound somewhat interesting, you will need to take into account that these merchandise do not simply have their very own odors—they will additionally impart these smells to different foodstuffs within the fridge. If you wish to give them a shot, merely set a small bowl within the fridge, crammed with both espresso grounds or vinegar (or purchase a canister of odor-eliminating gel to maintain on a shelf). Simply take into account that it’s possible you’ll discover a new scent invading your fridge and its contents, somewhat than what we actually need—no scent in any respect.

Does Baking Soda Actually Remove Odors?

For higher outcomes, we have to take a look at possibility quantity two: lowering the variety of odor molecules floating round your fridge. Since you’ve got already tried baking soda with no complete lot of luck, let’s discuss why it does and doesn’t work notably properly as an odor neutralizer.

In case you have the impression that baking soda works by attracting dangerous smells after which systematically destroying them, you are not alone. However you are additionally improper. Baking soda is not a magic beacon for smelly molecules. Its repute as an odor eliminator exists as a result of it could actually seize and maintain scents—a course of scientists name adsorption.

Adsorption works by offering a floor on which smelly gaseous molecules can land and cling. In comparison with, say, the partitions of your fridge, baking soda makes for a fairly respectable, porous floor, however in case you’re maintaining it in its field, its results shall be restricted. For starters, it’ll have to be in shut proximity to the supply of your drawback. And even then, the comparatively small floor space would not have the form of capability you most likely have to neutralize the scent.

One resolution to this quandary is to decant small quantities of baking soda—say, an eighth to 1 / 4 cup at a time—from the field to a plate or bowl with a view to improve the floor space, after which change it often. However that is a bit cumbersome, proper?

So, if baking soda will not do an important job at maintaining fridge smells at bay, what is going to? Do not hand over on adsorption but!

A Higher Odor Answer: Activated Charcoal

Enter activated charcoal, which additionally goes by the names lively charcoal, lively carbon, and activated carbon. Activated charcoal has an enormous ratio of floor space to quantity. To return to our ship metaphor, it is kind of like a marina, with slips for a lot of, many boats packed effectively in a really small area. In different phrases, it is nice at trapping the offending odor molecules. It is obtainable in brick kind, in addition to in sachets, although you may also DIY it by pouring free activated charcoal into small material baggage, or perhaps a clear sock.

For a lot of, the most important downside to activated charcoal is that it would not come low-cost. No less than, not the type that is labeled to be used in your fridge. However this is the factor: It is also generally used for aquarium filters, and pet suppliers will promote it for a complete lot much less. The activated charcoal marketed as an odor eliminator prices round 81¢ per ounce, whereas the identical stuff marketed for aquarium filters will run you solely 35¢ per ounce.

The tl;dr model of that is, primarily, that people treatments like utilizing baking soda (or white vinegar, or espresso grounds) to eradicate odors within the fridge could also be unhazardous and exceedingly cheap, however they simply do not work all that properly. Fortuitously, activated charcoal does work and, in case you do not thoughts a small DIY effort, could be fairly cost-effective if bought free and transferred into sachets. As a bonus, you may also use these sachets to clear the air, so to talk, in different areas of the house, like a stuffy closet or a musty basement, or—if we’re being actually sincere with one another—the toilet.
