Here's an uncomfortable truth about bathroom cleaning. Most of us just give the toilet brush a decent rinse, drop it back into its canister or wall mount holder, and consider the job finished. The brush might look fine, but the holder has been quietly collecting everything that has dripped off the brush for the last eight months.
That container at the bottom is almost always the dirtiest thing in the room. Not the bowl. Not the seat. The holder.
If you've ever lifted the brush out and been hit with a smell you couldn't quite place, or a sight you’d rather not investigate, this guide is for you. Whether your toilet brush holder sits on the floor or is attached to the wall, the cleaning job is largely the same. We'll cover the full cleaning process for typical toilet brush holders below, then look at the one design on the market that actually gets rid of the difficult-to-clean, oversized, heavy, or breakable brush holder altogether.
Why toilet brush holders get so dirty, so fast
It comes down to four things happening at once.
Water has nowhere to go. Every time you put a wet brush back, a small amount of water runs off the bristles and into the base. In a sealed or deep brush holder there's no airflow to dry the water out, so it just sits there. Over time it can build up to a shallow pool that marinates the brush when stored.
Bacteria and mould have everything they need. Standing water, organic residue, low light, no ventilation are an ideal set of conditions. What builds up is biofilm - a thin slimy layer that clings to the plastic or ceramic and won't shift with a casual rinse. That's the source of the smell, and it's why just tipping the water out every now and then doesn't fix anything.
Australian bathrooms make it worse. If you're in Queensland, Darwin, or anywhere with a proper wet season, summer humidity means the toilet brush holder essentially never dries out. Further south it's the opposite problem: during winter most of us keep the bathroom window shut and run the exhaust fan for about four minutes before forgetting about it. Same result either way.
Then there's the water itself. Adelaide and Perth tap water has higher mineral content, or “hard” water, so households there can get a chalky white ring of limescale in the holder on top of everything else. Melbourne and Sydney have softer water and usually escape that particular problem, though soft water won't save you from the biofilm build up.
What you'll need
Nothing exotic. Most of these are already under your sink.
- Rubber gloves (non-negotiable)
- White vinegar
- Bicarb soda
- Bleach or a bathroom disinfectant - White King, Domestos, Pine O Cleen, whatever you already use
- An old toothbrush or bottle brush
- A bucket, or a laundry tub you don't mind sacrificing for twenty minutes
- Paper towel or a Chux you're happy to bin
- Boiling water from the kettle
One safety note, and please take this one seriously. Never mix bleach with vinegar, and never mix bleach with anything containing ammonia. These combinations release chlorine gas, and in a small unventilated bathroom creates a dangerous environment. Only ever use one, rinse thoroughly, then use the other if you need to. Not both at once. Open a window for ventilation while you work.
How to clean a toilet brush holder: the step-by-step
1. Rinse the brush and park it
Hold the brush inside the toilet bowl and flush, rotate the brush letting clean water run over all sides of the bristles. Then hold the brush against the top of the toilet with the head hanging over the bowl, and close the toilet seat to clamp the brush in place. This allows the brush to drip into the bowl while you deal with the holder. It looks ridiculous, but it works.
2. Empty the holder into the toilet
If your brush holder is wall mounted, twist or pull the canister out of the wall bracket. Tip any liquid contents from the brush holder straight into the toilet and flush. If you’re worried about splashing or making a mess, take the whole holder out to the garden or somewhere you can rinse with water afterwards.
3. Pour boiling water into the holder
Straight from the kettle. This does more than people expect - it loosens the biofilm on the walls of the container and takes the edge off the smell before you've scrubbed anything. Let it sit for two or three minutes, then tip it out.
4. Scrub with bicarb
Sprinkle a generous amount of bicarb soda into the damp holder and work it around the inside with your old brush. Pay attention to the bottom corner where the wall meets the base - that seam is where the worst of it accumulates and where a cloth simply can't reach. This is the part most people skip, but it's the part that actually removes the grime causing the odour. Rinse any residual bicarb out before moving on.
5. Deal with the build-up (hard water households)
If there's a white crusty ring, that's limescale and bicarb won't affect it. Fill the holder with white vinegar, or a half-and-half vinegar and hot water mix, and leave it for a couple of hours. Even overnight if it's really set in. The acidity dissolves the mineral deposit and it wipes away with minimal effort afterwards.
Rinse the vinegar out completely before using any bleach.
6. Disinfect
Now the surface is physically clean, disinfect it. Fill the holder with a diluted bleach and water solution, or spray it down with your bathroom disinfectant and leave it for the time recommended on the label, which is usually five to ten minutes. Disinfectant applied over a layer of grime doesn't achieve much, which is exactly why this step comes after scrubbing.
7. Dry it completely
This is an important step that determines whether you're doing this again in three weeks or three months. Rinse any remaining disinfectant, then leave the holder upside down in the sun for an hour if you can, or wipe it dry with paper towel and leave it out overnight. Moisture is the entire problem; we don’t want to reintroduce it.
Give the brush the same treatment before it goes back - a soak in hot water with a splash of disinfectant, then let it dry fully.
Not all holders clean up equally
Worth knowing before you spend an afternoon on one that's beyond saving.
Floor standing holders are the ones most people have. A deep enclosed canister is the hardest to keep clean - the narrow opening means you can’t get your hand in, the base is often unreachable, and many have sharp internal corners that trap residue permanently. Ceramic and metal versions clean up beautifully and resist staining, but they’re heavy, and once the surface goes – a chipped glaze, pitted chrome plating – so does the holder’s ability to be cleaned properly. All of them sit directly on the floor, so any drips around the base leave a damp ring on the tiles and work grime into the grout. Remember to clean the floor underneath every time, not just the holder.
Wall-mounted holders get everything up off the floor, so you’re not dealing with the dust and grime collecting around the base. They typically have a removable plastic canister that you twist or pull out from the wall mount. But the canister itself is just as much effort to clean as the floor standing version – same narrow opening, same trapped residue, just mounted higher.
There’s one exception to all of this – a wall mounted design that does away with the bulky canister altogether. More on that below.
How often should you actually do this?
Realistically:
- After every use: rinse the brush in the flush, tap it dry against the inside of the bowl, letting as much water as possible drain from the bristles before it goes back
- Weekly: tip the holder contents into toilet, rinse, and dry it out
- Monthly: the full clean above
If your toilet brush holder is permanently damp inside, or you're cleaning monthly and it's smelling again within a fortnight, the design is working against you. That's not an issue with your cleaning technique.
When to stop cleaning and start replacing
Some toilet brush holders can't be recovered. Bin it if you're seeing:
- Staining that survives bleach
- A smell that returns within days of a full clean
- Visible mould in seams or areas you can't access
- Rust on metal components or flaking of the metallic plated finish
- Cracks or chips in ceramic, which trap moisture permanently
A holder that needs scrubbing to remove smell weekly isn't worth keeping.
The quiet cost of a cheap holder
Worth doing the sums, because most people never have.
The $25 holder from the hardware store lasts eighteen months if you're lucky. Two years, if you're diligent and fortunate enough that the finish lasts. Then it's stained, or it smells, or the chrome is flaking off, and you replace it. Over ten years that's five or six of them, plus the hours spent over those ten years trying to rescue something that was never designed to be rescued.
It's not really about the money, it's that you keep buying the same problem.
The alternative is to buy the problem out once. Stainless steel doesn't stain or flake. A drip cup that detaches and rinses in thirty seconds never accumulates enough to need a deep clean. And a brush that sheds water instead of retaining it doesn't create the pool of water in the first place.
Designing the problem out
The honest conclusion after all of this: the best toilet brush holder is one that doesn't hold water to begin with, and as far as we're aware, Valet is the only toilet brush holder built this way.
The Valet Toilet Brush Ensemble was designed for exactly that, by an architect and a mechanical engineer who had a combined thirty-five years of bathroom design and product manufacturing experience, and had grown tired of the one fitting nobody had bothered to solve properly.
It's Australian designed and wall mounted, so nothing sits on your floor collecting dust. The stainless-steel holder keeps the brush fully enclosed between uses - no open bowl of liquid, no exposure, no mess. The plastic drip cup at the base detaches in seconds and is small enough to rinse under a basin tap, which means no reaching into a container you can't see the bottom of.
The anti-microbial silicone bristles are short and widely spaced, so they shed water and tap dry rather than carrying half a bowl's worth back into the holder. Less water in means less to clean out. It also stores two spare rolls, which is a small thing right up until you need one.
For anyone maintaining toilet brushes in bathrooms across hotels, healthcare and aged care facilities, the even more efficient approach is to keep additional drip cups on hand. Swap the dirty one out for a clean one during rounds, take it away to be cleaned properly. The amenity is back in service in seconds, and the drip cup cleaning can happen in bulk elsewhere rather than individually in each room.
It comes in a variety of finishes to match your existing tapware, and it won an A'Design Award in Italy, which for a toilet brush, gives you some sense of how seriously it was taken.
If you've read this far, you already know this is the easier and more hygienic way to do this. Pre-order yours, or get in touch if you'd like to talk through finishes or ask about multiple units for a project.
One thing worth knowing about timing
The first production batch hasn't shipped yet. Valet is currently open for pre-orders, and the initial run is limited. Once it's allocated, the next batch is some months away.
Frequently asked questions
Can I put a toilet brush holder in the dishwasher?
Please don't. Even on a hot cycle it's not hygienic and not a risk to take with something you eat off. Hand clean it in a laundry tub or outside, and keep it well away from the kitchen.
Why does my toilet brush holder smell even after cleaning?
Almost always biofilm in a seam or area you haven't reached - usually the sharp inside corner where the base meets the wall of the container. Scrub it mechanically with a narrow brush rather than relying on disinfectant, and make sure it dries completely afterwards.
How do I clean a wall mounted toilet brush without taking it off the wall?
You shouldn't need to remove it from the wall – most designs have a plastic or metal canister that twists or pulls out from the holder. Empty and clean the canister in the same way as any other holder. Remember to also wipe down any drips or grime on the wall mounted parts.
Should I keep disinfectant sitting in the bottom of the holder?
It's a common habit but it doesn't really work well. The solution dilutes with water from every wet brush, loses effectiveness within days, and by the end of the week you've got a container of contaminated liquid. A dry holder beats a wet one holding weak disinfectant.
Is vinegar or bleach better for cleaning a toilet brush holder?
They do different jobs. Vinegar is acidic and dissolves limescale and mineral build-up. Bleach contains sodium hypochlorite and acts to disinfect. Use vinegar if there are crusty white deposits, rinse it out fully, then disinfect. Never combine the two chemicals.
How do I stop mould growing in the holder?
Airflow and dryness. Run the exhaust fan for at least twenty minutes after a shower, always tap the brush as dry as possible before returning it to the holder, and choose a toilet brush holder that is easier for you to clean.
What if something goes wrong with a wall mounted unit after installation?
Check what the manufacturer stands behind before you buy - mounting hardware and finishes are the two things that tend to fail first. Every Valet is covered by warranty, and the installation instructions come with each unit and are available to download from the product page.
