In search of the best toilet cleaner? Smart thinking. Arming yourself with some quality toilet cleaner is crucial in keeping your bathroom as welcoming and hygienic as possible. Granted, no one gets excited about cleaning the toilet, but it's a job made far easier with the right gear. When your loo smells fresh as a daisy, you'll thank us.

Because there are so many different options out there to pick from, we've done the honours of rounding up the very best money can buy. Some of you might prefer the standard liquid option in a bottle. Alternatively, you might opt for a powder or tablet choice, both of which come in handy when taking down limescale-ridden toilets. Perhaps, too, you're after something that will keep the lavatory sweet and fragrant 24/7? In which case, a rim block, which works its magic every time you flush, could be ideal. And if you can't stand the cleaning process at all, there's a zero-effort option out there that slots into your toilet's tank.

Of course, all of this is down to personal preference, so we'll let you decide on your favourite.

What is the best toilet cleaner?

We rate the Astonish Toilet Bowl Cleaner Tablets so much so, that we consider them the best toilet cleaner you can buy. They're cruelty-free and vegan, easy to use and they work wonders on any limescale, rust or calcium that may be in your bowl.

How to buy the best toilet cleaner

When it comes to buying the best toilet cleaner, the most important thing is that it kills germs and bacteria, so look for products that promise this at the very least. Some stamp out germs as well as tackling limescale and if you live in a hard water area, limescale is definitely your enemy so it’s worth looking for a loo cleaner that can help with this.

Decide if you want something eco-friendly that uses plant extracts rather than chemicals – a good idea if you have a septic tank or to do your bit for the planet – and whether the smell is important to you. Most toilet cleaners have a nice fresh fragrance such as marine or floral notes, while others have a bleachy odour.

Check the thickness of the toilet cleaner and whether the bottle has an angled head so you can get right under the rim for a really hygienic clean.

How do you clean a badly stained toilet bowl?

Sure, it's not the most luxurious question we've been asked, but it couldn't be more important when keeping a home to be proud of. When it comes to tackling the dreaded bowl, there are many ways to approach the task. One smart method is to use a bleach-based cleaner to disinfect the toilet, beginning below the rim. Then, you'll want to start scrubbing the sides – be sure to wear gloves as you do so. Finally, spray the outside of the toilet bowl with a disinfectant, being careful to cover the lid, chain and tank, too. Once it has been left for 10 to 15 minutes, you can wipe it down using a clean sponge. Et voilà!
