The bathroom is one of the most important spaces in the home when it comes to cleanliness and hygiene. It is also the room that tends to accumulate unpleasant odors the quickest, even when it appears spotless. No matter how often you scrub the sink, tiles, and toilet with fragranced cleaning products, it’s not uncommon to find that the freshness fades soon after. This can be frustrating, especially after you’ve put time and effort into deep cleaning.
Fortunately, there’s a simple and natural method that can help your bathroom stay fresh for days after every cleaning session. This easy trick uses common household items—a sponge, some coarse salt, a piece of soap, and an elastic band—to neutralize unpleasant smells and release a gentle fragrance every time you flush the toilet.
Why bathrooms lose their freshness quickly
Bathrooms, by their very nature, are prone to dampness, humidity, and the constant flow of water. These conditions create an environment where odors can linger, no matter how much air freshener you spray. Residue inside the toilet drain or pipes often becomes the main culprit, as even small buildups of waste or limescale can trap smells.
Air fresheners or cleaning sprays may mask the problem for a short while, but they rarely address the underlying issue. That’s why this sponge and salt method is so effective—it works directly at the source, inside the toilet system itself.
The natural deodorizing power of salt and soap
Before diving into the method, it’s helpful to understand why these ingredients are so effective.
-
Coarse salt is a natural deodorizer and mild disinfectant. It absorbs odors, reduces bacteria buildup, and helps prevent unpleasant smells from lingering.
-
Soap not only cleans but also releases fragrance each time it comes into contact with water, adding a light, fresh scent to the bathroom.
Combined, these two ingredients create a small but powerful tool that refreshes your bathroom in a natural and inexpensive way.
What you will need
To prepare this bathroom freshening solution, gather the following items:
-
A regular dishwashing sponge (the kind with a soft yellow side and a green abrasive side works perfectly)
-
A tablespoon of coarse salt
-
A small piece of bar soap (any type you usually use for hands or body)
-
A simple elastic band (like those used on masks or for bundling small items)
-
A pair of scissors
All of these items are likely already available in your home, making this method not only practical but also cost-free.
Step-by-step guide to making the sponge deodorizer
-
Prepare the sponge
Take the sponge and, using scissors, make a small hole in the yellow, softer side. The hole should be deep enough to hold the salt without breaking through the other side. -
Fill with salt
Place about one tablespoon of coarse salt into the hole. Use your fingers to gently push the salt further inside so it stays secure at the bottom. -
Seal with soap
Take the piece of bar soap and press it into the hole to cover the salt. The soap acts as a seal, keeping the salt in place while also adding its own fragrance. -
Attach the elastic
Make a second, smaller hole in the sponge to thread the elastic through. This will serve as a “handle” later, allowing you to easily place and retrieve the sponge from the toilet system.
At this stage, your homemade bathroom deodorizer is ready for use.
How to use it in the bathroom
The sponge works best when placed in the toilet system itself. To do this, lift the cover of your toilet’s flush tank or drain section. Place the sponge inside, ensuring that the elastic band remains slightly outside for easy retrieval later. The sponge should be in contact with the water so that each time you flush, both the salt and soap are gently released.
Once the sponge is in place, replace the cover of the flush tank or drain lid. The elastic band can rest discreetly on the side, ensuring the sponge stays in a vertical position without being visible.
What happens after installation
Every time you flush the toilet, the water comes into contact with the sponge. The salt works to reduce odors at the source, while the soap gradually dissolves and releases a pleasant fragrance into the bathroom. Instead of unpleasant smells, you’ll notice a light freshness that lasts for days.
This method also has the added benefit of being very inexpensive. Rather than constantly buying toilet fresheners, rim blocks, or chemical sprays, you can rely on everyday household items. The sponge can easily be refreshed by adding more salt and replacing the soap when needed.
Benefits of this method
-
Long-lasting freshness: Unlike sprays that fade quickly, the sponge releases fragrance with every flush.
-
Eco-friendly: No harsh chemicals are needed—just natural ingredients.
-
Budget-friendly: Uses items you already have at home, saving you money on air fresheners.
-
Practical and discreet: The sponge remains hidden inside the flush system, so it doesn’t interfere with the look of your bathroom.
Final thoughts
A clean bathroom should not only look spotless but also smell fresh and inviting. With this simple sponge and salt trick, you can keep unpleasant odors at bay for days without relying on expensive or chemical-laden products. The preparation takes just a few minutes, but the results are impressive and long-lasting.
Next time you finish cleaning your bathroom, try this easy DIY method. You’ll be surprised at how effective a small sponge filled with salt and soap can be at transforming your bathroom into a fresher, more welcoming space—flush after flush.
