Bloo 2in1 In-Cistern Toilet Blocks Original, Pack of 4, Limescale Remover Cistern, Cleaner with Cleaning and Foaming Action, Fresheners

I’ve found they’ve lasted fairly long - about two weeks in and the block is still slowly working away. I get the bubbles after each flush but this has made no difference to the limescale in my bowl. I had to use citric acid separately to remove the bowl scale and I’ve actually noticed the limescale turning yellow from the holes under the rim since using this. So it’s a no for limescale removal and strange that it hasn’t been able to bleach that….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.

I live on a chalk hill. It's an aquifer and my tap water comes from the deep reservoir within it - which is why my tap water always comes out chalk white! I have to run it for some time for it to become clear. It deposits lots of limescale into everything that needs a water supply, including my toilet and cistern.Nothing has worked well enough to remove much of the limescale that's built up in my cistern and toilet bowl too (to a lesser degree), despite many products and much scrubbing. The flush has even become less powerful over time, from the limescale I can't reach! I bought these Bloo cubes on a whim, purely because I'd not tried this particular Bloo product yet. I'm constantly searching for anything to do the job better. These turn the water blue and smell nice. It's a clean smell and not overpowering when the loo is flushed either. It's just enough for the bathroom to smell nice. I suppose it could smell stronger but it's not the smell I'm interested in, as long as it's not a choker.Less than 24 hours after popping one in the cistern I noticed the limescale was reduced and within 1 week the flush was more powerful! I couldn't believe it. One cube lasted us 5 weeks in total and during week 4 the flush was really good, flushing almost as well as it used to!The toilet bowl is definitely not coated in as much limescale either, it's more shiny and definitely smoother. It also helps keep the toilet clean after use, meaning now it just needs a quick clean daily and a weekly scrub. As the only cleaner in my household this is definitely a good thing!As you can likely tell, I'm very pleased with this product and I hope it works as well for other people. I had a lot of scale to remove compared to a lot of other toilets I've seen or cleaned, but I assume it'll work well in a situation with less scale, although perhaps it might not be as noticeable as the changes I've seen.There's a green Bloo cube that keeps away limescale. I've not tried that yet as I'm still on my 2nd blue cube (not as much of an improvement to report as the first cube used), but I'll certainly consider it after this cube has finished. I'm hoping it'll maintain this this reduced level of limescale. If not, I'm back to these blue Bloo cubes... until I find a better product!
