It’s a great option for those looking to maintain a clean, fresh-smelling toilet
The Bloo Toilet Blocks Limescale Prevention offer an easy and effective solution to keeping your toilet fresh and free from limescale build-up. These toilet blocks are designed to be dropped into the toilet cistern, where they work to help prevent limescale and grime while providing a fresh, clean fragrance with every flush. Here’s an honest review of its features, pros, and cons: What’s Great: Effective Limescale Prevention: One of the key benefits of these toilet blocks is their ability to prevent limescale build-up in the toilet bowl. In areas with hard water, limescale can accumulate quickly, making the toilet look unsightly and difficult to clean. Bloo Toilet Blocks help to reduce this build-up, keeping your toilet cleaner for longer and making it easier to maintain. Fresh Fragrance with Every Flush: The Bloo Toilet Blocks come with a fresh, pleasant fragrance that’s released with every flush. The scent is clean and subtle, not overpowering, making it ideal for people who want a fresh-smelling toilet without a strong chemical or artificial odour. It helps to maintain a hygienic atmosphere in the bathroom, ensuring a refreshing experience each time you use the toilet. Convenient and Easy to Use: These toilet blocks are very easy to use – simply drop one into your toilet cistern and let it dissolve over time with each flush. There’s no need for complicated installations or messy applications. The simplicity of the product makes it a hassle-free addition to your toilet cleaning routine, perfect for those who want an easy and effective way to keep their toilet in good condition. Long-Lasting: The Bloo Toilet Blocks are designed to last for an extended period, so you won’t need to replace them frequently. Each block provides continuous cleaning and freshening for up to several weeks, making them a cost-effective option for long-term use. This means you get reliable, ongoing protection against limescale without needing constant replacement. Helps Maintain Toilet Hygiene: By preventing limescale and providing a fresh scent, Bloo Toilet Blocks also help to maintain overall toilet hygiene. They provide a bit of extra cleaning power between deep cleans, helping to keep your toilet looking and smelling fresh for longer periods. What Could Be Improved: Limited Limescale Removal Power: While the toilet blocks are great at preventing new limescale build-up, they may not be as effective at removing existing limescale deposits that have already formed in the toilet. If your toilet has significant limescale stains, you might need a more powerful cleaner in addition to the toilet blocks for a deeper clean. Fragrance May Not Last Long Enough for Some Users: Some customers have noted that the fragrance provided by the toilet blocks doesn’t last as long as they would like. While the scent is pleasant initially, it may fade more quickly than expected, especially with frequent flushing. This may require replacing the block sooner than anticipated for those who want a consistently fresh scent in their toilet. Effectiveness May Vary by Water Hardness: The effectiveness of Bloo Toilet Blocks can vary depending on the hardness of the water in your area. In places with very hard water, the blocks may not prevent limescale as effectively as in areas with softer water. If you live in an area with extremely hard water, you might need a more specialised solution for tackling limescale build-up. Noteworthy Observations: Affordable and Accessible: The Bloo Toilet Blocks are relatively inexpensive and can be found easily in most supermarkets and online stores. This makes them an affordable option for anyone looking to maintain a fresh-smelling, limescale-free toilet without spending too much on expensive cleaning products. Environmentally Friendly Option: While the product provides effective cleaning and fragrance, it’s worth noting that the packaging is plastic-based, and users concerned about environmental impact may want to look for alternative products with eco-friendly packaging or biodegradable options. However, the convenience and effectiveness of the product may outweigh this consideration for many. Verdict: The Bloo Toilet Blocks Limescale Prevention are a simple, affordable, and effective way to keep your toilet fresh and reduce limescale build-up, especially in areas with hard water. Their ability to provide a clean fragrance with every flush and prevent new limescale accumulation makes them a worthwhile addition to your toilet cleaning routine. While they may not be as effective at removing existing limescale stains and the fragrance could last longer, the product delivers on its promises of convenience and ease of use. Overall, it’s a great option for those looking to maintain a clean, fresh-smelling toilet without the need for constant scrubbing.

Smell lovely
Really pleased with these Bloo cistern blocks. They leave the toilet smelling fresh and help keep it clean between deeper cleans. The fragrance is noticeable but not overpowering. They are easy to drop into the cistern and last a good amount of time, so they feel like good value for money. The water has a nice fresh scent after each flush which makes a difference. Overall a simple product that works well and does what it should. Would definitely buy again.

Excellent value for money
Here’s a straightforward, down-to-earth “Amazon”-style review for [Bloo Toilet Blocks]() (sometimes referred to as the “Bloo toilet cube”) — what works, where it might disappoint, and who it’s good for: ⭐⭐⭐⭐☆ Good for basic maintenance — handy, though don’t expect miracles I picked up these Bloo Toilet Blocks because I wanted a quick, easy way to keep the loo fresh between full cleans. They’re dead simple to use — you just drop the cube into the cistern (wrapper “as is,” it dissolves automatically) and it works with each flush. The water goes a nice blue, there’s a fresh scent, and it definitely helps mask odors rather than letting the bowl go stale between deep cleans. For a week or two they seem to keep things cleaner than no treatment at all — less surface grime, fewer odors, and the loo smells “taken care of.” But the downsides: if your toilet already has serious limescale or staining the cube won’t blast that out — it’s more about maintenance than heavy-duty cleaning. Some reviewers say the advertised longevity (a few weeks or hundreds of flushes) is optimistic — you might find yourself replacing the block sooner than expected. So, in simple terms: it’s convenient, low-effort, and decent for keeping a toilet fresh and reasonably clean between deeper scrubs, but if you need serious cleaning or limescale removal you’ll need a supplemental product. Excellent value for money.

Effective and Convenient Limescale Remover
I’ve been using the New Bloo Toilet Blocks for a few weeks now, and I’m really pleased with how effective they are at keeping my toilet clean and free from limescale buildup. The blocks dissolve slowly, so I don’t have to replace them often, which makes them very convenient. They help maintain a fresh scent in the bathroom without being overpowering. Installation is straightforward—just pop the block into the cistern, and you’re good to go. Since using these blocks, I’ve noticed less limescale on the toilet bowl and in the cistern, which is great for prolonging the life of my toilet. Overall, I’d definitely recommend these to anyone looking for an easy, low-maintenance solution to limescale problems.

Preferred the round older version
Bought these as I could no longer buy the round toilet cleaner. It doesn't clean as well as the older version. Plus you need to regularly check it has completely dissolved in your cistern.

Better than ‘bog’ standard
Definitely worth the money , keeps the bowel clean , helps with air freshness but a bit slow fighting limescale ,in the cistern but does work if you keep using it

I thought it was just me, but seeing few reviews iam convinced. The blocks lasted for just over 5 days. It had a great fraganace but disappointed as it lasted only for few days against the 800 times that is being advertised. Would love to have a refund. I think this is the least that should be done.
