The best toilet cleaners, tried and tested for a squeaky-clean loo every time
Bust stubborn stains and stinky smells with ease
Tested by Blossom Boothroyd, Reshma Akhter and Jasmin Joyce
Let’s face it — cleaning the toilet is nobody’s idea of fun. It’s arguably the least glamorous of all household chores, yet one of the most important. A sparkling loo isn’t just about appearances; it’s essential for good hygiene, helping protect your home from bacteria and unpleasant odours. And when the job matters this much, you’ll want products that actually do what they promise.
That’s where our Good Housekeeping Institute (GHI) experts come in. We’ve donned our rubber gloves, armed ourselves with toilet brushes and tested countless cleaners — scrubbing, flushing and wiping to discover the best toilet cleaners you can buy. Let’s just say, our team has spent more time up close with a loo than we’d ever admit publicly.

To earn a place on our list, each product had to deliver real results in everyday homes. Our panel of testers used the cleaners over two weeks, assessing ease of use, stain removal power (on mould, limescale, and more) and that all-important fresh scent. Only the formulas that left toilets spotless — and testers genuinely impressed — made the cut.
Harpic Power Plus Toilet Cleaner
Harpic Power Plus Toilet Cleaner
Pros
- Versatile as it can be used to clean sinks, showers and more
- Required very little additional scrubbing
- Didn’t stain the bowl
Cons
- Hard to tell how much was left in the bottle
Score: 89/100
A firm favourite among our testers, Harpic impressed with its powerful cleaning performance and minimal effort required — exactly what you want from a toilet cleaner. It tackled tough stains, limescale and odours with ease, and most panellists reported that very little scrubbing was needed to achieve a sparkling finish.
The angled bottle design made it easy to reach under the rim, and the formula clung well to surfaces for an effective deep clean.
Many testers appreciated the mild, inoffensive scent, especially those sensitive to strong fragrances, although a few said they’d prefer a fresher or longer-lasting smell. The liquid’s bright blue colour divided opinion, but it didn’t stain or linger — and its coverage was notably even.
While the cleaner’s thin consistency meant some used more product than expected, and it wasn’t easy to see how much remained in the bottle, overall this bleach-based formula delivered consistent, satisfying results — making it a clear winner for reliable stain and odour removal.

Ecover Pine & Mint Toilet Cleaner
Ecover Pine & Mint Toilet Cleaner
Pros
- Popular scent
- Minimalist packaging and no neon-coloured liquid
- Plant-based and biodegradable ingredients
Cons
- It struggled with tougher stains
- The clear gel made applying the right amount of product tricky
Score: 86/100
Made with plant-based, biodegradable ingredients, this cleaner stood out as one of the most eco-conscious options we’ve tested. The fresh pine and mint fragrance was a clear hit with our panellists, and the ergonomic bottle design offered precise control when dispensing — helping you avoid waste. Plus, a little goes a long way, making it a budget-friendly and sustainable choice.
Testers found the formula clung well to the bowl and rim, effectively tackling odours and leaving the toilet visibly brighter. However, its performance on stubborn limescale and heavy stains was more varied — around half the panel felt it needed a bit of extra scrubbing power for deep cleaning.
Despite that, the feedback was overwhelmingly positive, with every tester saying they’d happily use it again — a solid everyday option for those wanting a greener clean without harsh chemicals.

HG Toilet Cleaner Gel
HG Toilet Cleaner Gel
Pros
- Thick formula coats the bowl really well
- Toilets were left noticeably brighter
- Mild and fresh scent
Cons
- Small size makes it less cost-effective
Score: 85/100
HG’s toilet gel cleaner stood out for its thick, adhesive formula and subtle, non-chemical scent, earning praise from those seeking a gentler, but still high-performing, solution.
The angled nozzle is good for targeted application and many panellists saw a noticeable difference in toilet brightness and limescale reduction after two weeks, with some calling it the best cleaner they’d used.
A few were disappointed by the small 500ml bottle, especially considering the price point. However, the majority of our testers were satisfied with its overall cleaning performance. This bleach-free gel is ideal for those who want a powerful, subtly scented option for regular or deep cleaning.

Aldi Power Force Thick Bleach
Aldi Power Force Thick Bleach
Pros
- Powerful and fast-working
- Strong results for tough stains and limescale
- Easy to dispense
Cons
- Hard to read the instructions
- Wasn't that effective at eliminating odours, despite strong bleach smell
Score: 84/100
This bleach-based toilet cleaner proved to be an excellent performer in testing, with panellists repeatedly praising how quickly it removed stains. One tester even reported seeing marks disappear within 30 minutes with no scrubbing required – the stuff of dreams. Many also noticed how effectively it brightened and whitened the bowl.
Its thick consistency helped the gel cling to the sides and reach under the rim, tackling stains and limescale with ease. Several testers also mentioned the satisfying foamy action after flushing, which reinforced its deep-cleaning feel.
The only downsides were its strong bleach scent and the small, hard-to-read label on the bottle. Overall though, testers agreed it delivered impressive cleaning power and said they would happily keep using – and recommending – it.

Pros
- Bleach-free
- Gets to work quickly
- Leaves surfaces clean, shiny and refreshed
- Great design that's easy to use
Cons
- Requires a bit more scrubbing than bleach-based alternatives
Score: 82/100
This bleach-free toilet cleaner earned strong praise for its ability to tackle limescale, everyday grime and odours, with several panellists noting how quickly it got to work.
The thick blue gel was easy to see and clung well to the bowl, leaving surfaces clean, shiny and refreshed. Testers also liked the bottle design; its contoured shape made it comfortable to hold and easy to direct under the rim for precise application.
Some users found it needed a little extra scrubbing on stubborn stains, and it wasn’t quite as powerful as bleach-based options. Still, that’s a trade-off many would make for a cleaner that’s gentler on the environment.
A few testers disliked the scent or mentioned slight residue if not rinsed thoroughly, but the majority were impressed with its cleaning ability, ease of use and overall performance.

Duck Deep Action Gel Toilet Cleaner Liquid
Duck Deep Action Gel Toilet Cleaner Liquid
Pros
- Lovely fresh pine scent that sticks around
- Cleverly designed nozzle makes cleaning under the rim a breeze
Cons
- Dispenses very quickly, so it's hard to control the amount used
Score: 80/100
Our testers loved this cleaner for its ease of use, pleasant pine scent and reliable performance on everyday grime and toilet stains.
The brand’s signature duck-neck nozzle made it easy to apply the gel under the rim, and panellists appreciated its thick texture, which clung well to the bowl for effective coverage.
However, several users found that the gel dispensed too quickly, making it tricky to control how much product was used. Some also noticed that it left faint coloured streaks, which needed extra flushing or a light scrub to remove. Its results on stubborn stains and limescale were more limited than our top performers, but it still impressed as a quick, fuss-free option for regular cleaning.

The Pink Stuff Toilet Gel Cleaner
The Pink Stuff Toilet Gel Cleaner
Pros
- Great for getting under the rim
- Pleasing floral scent
Cons
- Divisive colour
- Struggled with really stubborn stains
Score: 77/100
This toilet cleaner impressed our testers with its ease of use, pleasant floral scent and reliable performance on everyday grime. Although the formula was a little thin for some, it clung well enough for routine cleaning, and most panellists said it left the bowl looking clean and fresh.
Its bright pink colour divided opinion – some liked how visible it was during cleaning, while others found it a bit too bold.
Performance on tougher stains and limescale was mixed: most saw noticeable improvement with minimal scrubbing, but only about half felt it was truly effective on the most stubborn marks. Still, with a bleach-free formula, simple instructions and a fragrance several testers described as “divine,” this remains a solid choice for regular, fuss-free cleaning.
Key specifications
| Size | 750ml |
|---|---|
| Cost per litre | £1.54 |
| Bleach-based? | No |
Pros
- Straightforward and fuss-free
- Subtle bleach smell
- Delivered results in just 5 minutes
Cons
- Could have clung to the bowl better
- Struggled with stubborn stains
- Hard to tell how much is in the bottle
Score: 76/100
Testers praised this cleaner for its effective stain removal, easy-to-hold bottle and subtle bleach scent – a rare find in bleach-based products. Unlike harsher alternatives, it left bathrooms smelling fresh rather than chemical-heavy. The clear formula also earned points for not staining porcelain, and many noted how quickly it worked, often showing visible results within five minutes.
Despite being marketed as a “seriously thick” bleach, some users found the formula thinner than expected and felt it could have clung better to the bowl. It also needed more effort on limescale and heavy build-up.
Still, with clear instructions, a secure safety cap and a precise nozzle, this proved to be a dependable, no-nonsense choice for regular toilet cleaning.

Pros
- Great price-point for an affordable option

- Struggled on stubborn stains and limescale
- Child-proof cap proved difficult to remove
Score: 75/100
This affordable bleach-based toilet cleaner impressed testers by leaving porcelain shiny and removing everyday marks with ease. Many liked the pleasant, not overpowering, bleach scent (we tested the original version, though it’s also available in a citrus option), and the nozzle design made it simple to apply under the rim.
Some users felt the bleach was thinner and less concentrated than they’d prefer, and a few found the child-proof cap tricky to open.
Even so, most testers said they’d keep using it, making this a reliable, low-cost choice for regular cleaning and quick refreshes.

- Fragrance lingers for a fresh, clean bathroom feeling
- A reliable pick for everyday cleaning
Cons
- Gel is a little on the thin side and struggled with limescale stains

How we test toilet cleaners
To find the best toilet cleaners, our experts looked well beyond scent and sparkle. Each product was tested by a panel of 10 people who used the cleaners in their own homes, ensuring results reflected real-world cleaning needs. The goal was simple: to discover which products genuinely perform — from the first squirt to the final flush.
Testers evaluated each cleaner across key criteria, including ease of use, packaging and design, clarity of instructions, fragrance, and, most importantly, overall cleaning power. We wanted to know how well each one clung to the bowl, tackled grime and limescale, and whether it was easy to apply under the rim for a thorough clean.
Each cleaner was applied and observed in action, with testers assessing texture, consistency, and how effectively it removed dirt, stains and limescale. Depending on performance, they either flushed or scrubbed, noting whether the product worked independently or needed extra effort. Scent strength and longevity were also evaluated, along with how well each cleaner neutralised lingering odours.
To keep things fair and thorough, testers followed a detailed checklist provided by the Good Housekeeping Institute — covering everything from ease of use to the clarity of the label text. Their feedback was captured through a structured survey, with each cleaner given a numerical score. Finally, they were asked one crucial question: Would you buy and use this again?
The result? A clear, honest picture of how each toilet cleaner performs in real homes, helping you find one that leaves your loo gleaming — without the guesswork.

Pros

- Silicone head traps less dirt and water than traditional bristles
- Stylish, compact design
Cons
- No refill line
Score: 82/100

Testers loved the slim, modern, and quick-draining silicone design, which trapped less gunk than a standard toilet brush. “Feels more sanitary than your standard old school toilet brush,” said one tester, “and it looks a little more elevated next to your loo!" Others praised the built-in dispenser, with one telling us they "love the fact it dispenses toilet gel to clean while it works", making regular maintenance quick and convenient.

Bloo Self Active Fresh Flowers Toilet Rim Blocks, Pack of 2
Bloo Self Active Fresh Flowers Toilet Rim Blocks, Pack of 2
Pros
- Pleasant fragrance that isn’t too strong
- Long-lasting
Cons
- Better for maintenance than deep cleaning
Score: 76/100
This toilet rim block is a great way to make everyday loo maintenance a little more hands-free. You simply hang it from the rim of your toilet bowl where the water flows out and watch your flush turn into bright blue toilet cleaner. Most of our testers found it an effective way to get rid of stains, and it scored particularly well for removing unpleasant odours.
Panellists were also really impressed with how long the block lasted and found it easy to attach to the rim. Just note that due to the long, straight shape, it may not be the best fit for small, rounded toilets. The pleasant fragrance was also a hit, with panellists describing it as “lovely and fresh without being too overpowering”. A great way to keep a fresh toilet in between deep cleans.
Why trust the Good Housekeeping Institute
At the Good Housekeeping Institute, we’ve been testing cleaning products for over 100 years, covering everything from the best laundry detergents to the best dishwasher tablets, and we don't cut corners. Our rigorous approach combines analysis of ingredients with real-life testing to ensure every product recommendation reflects how you’ll actually use it in your home.
When it comes to toilet cleaners, each one is put through its paces by our panel of at-home testers. Their feedback is then gathered through detailed surveys and passed to our household advice writer, Ella Duggan.
Ella has written countless cleaning and decluttering guides for Good Housekeeping, with a keen eye for what really works. Whether it’s the best all-natural surface cleaners or clever solutions for tackling stains on the go, she knows how to separate the gimmicks from the game-changers.
How to get rid of brown rings around the toilet bowl
To tackle those stubborn brown rings around your toilet bowl, start by pouring about two cups (475ml) of white vinegar into the bowl, making sure it covers the stained area. Leave it for at least 30 minutes to let the vinegar break down the buildup. If the mark’s still there, sprinkle some baking soda on top and scrub gently with a toilet brush.
For stains that refuse to shift, try using a wet pumice stone and lightly buff the area — it sounds unusual, but our household advice editor swears by this trick for removing marks without scratching the porcelain.
To prevent the rings from returning, consider installing a water softener to reduce mineral deposits, and keep up with regular cleaning. A toilet cleaner containing citric acid can also help dissolve mineral buildup before it has a chance to form.
How often should you clean a toilet?
To keep your toilet hygienic and free from germs, aim to clean and disinfect it at least once a week. Regular cleaning helps stop bacteria from building up and keeps your bathroom smelling fresh. If someone in your household is unwell, it’s best to disinfect the toilet every two to three days, especially during cold and flu season.
Just as important as cleaning the toilet itself is caring for your cleaning tools. Toilet brushes can harbour mould and bacteria if left damp, so disinfect them after every use. Spray the bristles with disinfectant, then let the brush air dry by wedging it between the toilet seat and bowl (keeping the bristles above the water).
For gloves, sponges and other plastic cleaning tools, soak them in a bleach solution made from three tablespoons of bleach per litre of water for around five minutes. Rinse and allow them to air dry completely. Keeping your cleaning supplies fresh and germ-free helps ensure every scrub leaves your bathroom truly clean.
The verdict: What is the best toilet cleaner?
So, where should you put your money? Well according to our testers, Harpic Power Plus Citrus Toilet Cleaner is the best bet for a sparkling toilet bowl time and time again. It emerged as the top overall choice, earning high marks for its powerful performance.
If you prefer an eco-friendlier option, the Ecover Pine and Mint Toilet Cleaner is a standout solution. It scored highly for its plant-based, biodegradable ingredients and delightful scent.
