Harpic Powerplus Active Tablets, Original Scent, Pack 1 x 8 Tablets, Deep Clean Without Scrubbing, Removes 100% Limescale, Toilet Cleaner

It just works as it says. No scrubbing is needed. My toilet was quite bad and I dropped two tablets in and left overnight. 70 % of the stain gone. Dropped one more and left it overnight again and I said it's pretty much done. Great product.

Really do the job. 4 out of 5 because if you’re not careful their blue can stain other parts of the toilet where it’s difficult to remove it from e.g. toilet seat cover

This has to be the best toilet cleaning product I’ve ever tried - and I’ve tried a LOT over the years!It is quite fast acting like the box instructions say, however I find for the best stain removal result you are best to leave it sitting over night if possible.Very easy to use; just open the packet and drop the tablet on the water, then leave to stand. Flush away when finished. I also find the smell to be pleasant and quite mild. I’m asthmatic and a lot of cleaning products can trigger an attack, but I’m perfectly fine with these. Highly recommend to all!

Love these tablets for cleaning the loo. Used regularly they keep it looking good

It works very pleased with it.

Decided to order as most of the reviews were positive but wasn't that impressed. Left the tabs from midnight to 9am the next morning and still left some staining and our loos weren't that bad. Think Harpic and bleach do just as good a job

Easy to use and effective

These are great , left over night, a quick rub and all marks were gone . Can't recommend enough
