Bloo New Toilet Blocks Limescale Remover, Original Blue, Pack of 2

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!

Very poor product. No blue colour. Totally in effective.

Worked good but delivery took weeks. You know is Amazon people like our stuff delivered quickly.

They are working but dissipate too quickly

Good value, quality, smell, and foam s
