Harpic Power Plus Deep Cleaning Toilet Tablets, Original, Pack 1 x 6 tablets, Deep clean without Scrubbing, Removes 100% limescale, Toilet cleaner

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.

Great for getting stubborn stains and limescale off toilet bowls. Just drop it in the bowl and leave it for a couple of hours, brush and flush. Buying this multi bundle also saves money.

Really gets rid of timescale in toilet.Easy to use,just throw into toilet bowl leave ,then flush .

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 👍🏻

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