Power Plus Deep Cleaning Toilet Tablets, Original, 6 pack | Cleans where the brush can't reach, For a hygienically clean toilet, Removes 100% limescale, No mess, Kills 99.9% of bacteria

Now with these, they actually foam but I had to treat multiple times for a mild stubborn stain that has been there for months. It removed most of it but what totally removed the stain was when I combined it with pumice toilet cleaner. The stain vanished and my toilet bowl returned to new. I still use it once a while to prevent build up.

These have become my preferred way of giving the toilet a really deep clean. They're incredibly easy to use. Just drop a tablet into the bowl, leave it for a few hours or overnight, then give it a scrub with the toilet brush. The results are excellent, leaving the bowl spotless with very little effort. One word of advice is to handle the tablets carefully when removing them from the packaging, as they're a strong cleaning product. It's also worth avoiding any splashes when brushing. Used sensibly, though, they do a fantastic job and I'll definitely be buying them again.

Fairly effective but have had to use 3/4 to make a noticeable difference

They’re very easy to use and leave the toilet looking noticeably cleaner and fresher. They also helped solve a strange issue I had where the water in the toilet bowl would start turning yellow after a few hours after flushing. I’m not sure if it was caused by bacteria or some build-up in the bowl, but after using these tabs four times the problem completely disappeared. They make regular toilet maintenance much easier, and I’ll definitely be buying them again 👍🏻

Not as good as others have said. Used a tab three times and still not clean. Tried two together but still not clean. Each time left for hours but no better.

Very pleased with how these performed. The smell is pleasant and they do foam up well, but only level with the water line. Value is good as only needed one for each toilet. Whist toilet not to bad, staining on base was a problem. Have use other cleaner prior and they did nothing apart from dissolve. Will purchase these again as required

Lets just say after a flush a rather unpleasant sulphur? eggy? wafting pong would emit from the loo - and I had tried a lot of things, but no joy - thought eventually I'd need a plumber in the check. Yes, I was cleaning limescale from the bowl albeit not able to get it all, but then never gave the actual piping and bend a thought so I had a really good research session. I'd already poured some white vinegar into the cistern overnight to help clean inside of that (it did, but the smell was still present) while I waited for these to arrive. Like someone else did, once they came, that night I placed two into the bowl and put the lid down, honestly crossing fingers but not expecting much. Morning came and woah, not only did my white loo bowl look white, but all the limescale that was hard to reach in it - gone. I flushed the loo and for the first time in months, no wafting pong, that was completely gone too. Give it a go before calling a pricey plumber. Hope this helps.

I use these over night (when the toiling less likely to be flushed... As they didn't remove much when trying them in the day but great after the night trial... removed stains..no foaming as such... Good value.
