The best toilet cleaners, tried and tested for a squeaky-clean loo every time

Score: 89/100

A firm favourite among our panellists, Harpic’s toilet cleaner delivered dependable cleaning power with minimal effort. What more could you want? Testers praised its ability to tackle tough stains and odours, with most finding little to no scrubbing was needed, even on limescale and urine build-up. The bottle’s angled design makes it easy to apply under the rim, and it adhered well to surfaces for deep cleaning.

People liked the mild scent, particularly those with sensitivities, though a few would have preferred a more refreshing fragrance. While the liquid's bright blue colour split opinion, it didn’t stain or overstay its welcome and provided satisfying coverage.

It is quite thin, so extra product was often needed, and many found it hard to tell how much was left in the bottle. Still, this was a winner overall thanks to its bleach-based stain removal powers.

Score: 86/100

Made with plant-based and biodegradable ingredients, this is one of the more eco-friendly toilet cleaners we've tested. The fresh pine and mint scent was a hit with panellists and we liked how the design offered precise control when dispensing. A little went a long way too, making it a cost-effective choice.

Testers noted that it adhered well to the bowl and rim, effectively removing odours and improving overall brightness. However, its performance on tough stains and limescale was mixed, with only half of the panel finding it effective for heavy-duty cleaning. Some extra scrubbing should help achieve a sparkling bowl though.

All our panellists were happy with the product overall and said they'd use it again.

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.

Score: 84/100

This bleach-based toilet cleaner proved a fantastic performer in testing, with panellists repeatedly praising how quickly it cleared stains. One tester claims to have seen marks vanish within 30 minutes; no scrubbing required whatsoever (the stuff of dreams). Many also noted how effectively it whitened and brightened the bowl. Its thick consistency helped the gel cling high up the sides of the toilet and reach under the rim, tackling stains and limescale effectively. Several testers also noticed a satisfying foamy action after flushing that reinforced its “deep clean” feel.

There's no denying it has a strong bleach smell, and we weren't keen on the small, hard-to-read label on the bottle. Overall though, all said they would keep using it and recommend it to others.

Score: 82/100

This bleach-free toilet cleaner earned strong praise for its ability to tackle limescale, general grime and odours, with several panellists noting how quickly it worked its magic.

The thick blue gel is easy to see and clung well to the bowl, leaving surfaces clean, shiny and refreshed. The bottle design also impressed testers; its contoured shape makes it comfortable to hold and easy to direct under the rim for precise application.

However, some found that it required extra scrubbing to lift really tough stains and it's not as powerful as bleach-based alternatives. But that may be a compromise you're happy to make for a product that's kinder on the environment.

While a few users disliked the fragrance and some said it left residue if not rinsed thoroughly, the vast majority of panellists were satisfied with its overall cleaning power and ease of use.

Score: 80/100

Our testers loved this cleaner for its ease of use, pleasant pine fragrance, and ability to tackle general grime and everyday toilet stains.

The specially shaped duck-neck nozzle, which the brand is famous for, made it simple to apply under the rim and panellists appreciated the thick gel texture, which clung well to the bowl.

However, several users said the gel dispensed too quickly, making it difficult to control the amount used. Some also found that it left behind coloured streaks that required multiple flushes or scrubbing to fully remove. Its performance on tougher stains and limescale was more limited than some of our top scorers too.

Score: 77/100

This toilet cleaner impressed our testers with its ease of use, pleasant floral scent and effectiveness at tackling everyday grime. The formula, though on the thin side for some, clung well enough for regular cleaning, and the vast majority of testers said it left the bowl looking clean and fresh.

Its bright pink hue was a point of contention – some praised the visibility it offered during cleaning, while others found it off-putting and a bit garish.

When it came to tough stains and limescale, results were also a little mixed: while most saw visible improvements with minimal scrubbing, only half felt it performed strongly on the more stubborn marks. Still, with a bleach-free formula, easy-to-follow instructions, and a scent described as "divine" by several people, this holds its own as an effective, everyday cleaner.

Score: 76/100

Testers praised this cleaner for its solid stain-removal power, easy-to-handle bottle, and subtle bleach scent – a rare quality in bleach-based products. Unlike harsher alternatives, it left bathrooms smelling fresh, not chemical-heavy. The clear formula also got points for not staining porcelain, and many loved how quickly this worked, often delivering visible results in just five minutes.

Despite being marketed as a “seriously thick” bleach, some users found the formula runny and felt it could have clung better to the toilet bowl. It also struggled with lifting limescale and tougher build-up.

Still, with easy-to-read instructions, a reliable safety cap and a precise nozzle, it proved itself a dependable staple for regular toilet cleans.

Score: 75/100

This cheap and cheerful bleach-based toilet cleaner left porcelain shiny and removed everyday marks. Many liked the pleasant, yet not overpowering, bleach scent (we tested the original cleaner; it also comes in a citrus scent) and the nozzle design made it easy to direct under the rim.

However, some said the bleach was thinner and weaker than they'd have liked, and the child-proof cap proved difficult to open, even for adults.

Overall, the majority said they'd continue using it, making it a good budget buy for everyday cleaning.

Score: 74/100

With a fresh, clean scent, ASDA's toilet cleaner was dubbed “the nicest-smelling toilet cleaner” they’d ever used by one panellist. The gentle fragrance lingered after flushing too and made the bathroom feel fresh and clean.

It scored highly for general cleaning, leaving bowls sparkling, especially with regular use. While it’s not the most powerful against heavy limescale, for day-to-day freshness and a consistently clean finish, this gel delivered reliable results.
