Power Plus Deep Cleaning Toilet Tablets, Original Scent, Pack 1 x 6 Tablets, Deep Clean Without Scrubbing, Removes 100% Limescale, Toilet Cleaner

These blocks are very effective, and do remove limescale and 'bits'. I put one in the toilet cistern, another in the loo, and leave them as long as possible (8 hrs is fine). They restore order, in a way ordinary blocks don't. I don't use them all the time, just once a month is valuable though.

I first tried removing the stain at the bottom of the bowl with bicarbonate and vinegar then with the toilet brush but nearly ended up breaking it. I had my doubts and considered buying another product but decided to give it a go. Used a 2 power plus tablets and a full bottle of Harpic powerplus 10X. Left overnight and all the limescale and grey marks are gone. Now looks like new. Get your toilet looking like new again for less than a tenner. Amazing stuff.

Works very well, maybe a little pricey, but zero effort so fair enough.

Cleans base of toilet leaving a pleasant smell. Will buy again

Didn't remove stubborn timescale from the sides of the bowl.

These are the best tablets to use on toilets that have limescale/staining issues. I live in a very hard water area. Pop one in before bed and in the morning the limescale is gone. Can be used on neglected toilets too which I have done in a rental property. Might need to use more than one but it will greatly reduce the need for scrubbing. Great value.

Bought these as I was influenced by an online review and they did not disappoint! I had been getting dark water leaking at the back of the toilets, into the bowl These have eliminated the problem on both toilets! I used these in the cistern with black harpic liquid in the bowl and they are both now gleaming! Cannot recommend enough

Not so good but would get rid of miner stains
