I bought this to specifically target quite a small patch of limescale in my loo. I've applied it 3 times, left it for a few hours, brushed it furiously and it doesn't work. Made absolutely no difference. Save your money.

I had to call the ambulance I near die with this product don’t buy that is very very dangerous . I sent a letter to the company right now about how I am feeling on the bed for 3 days

10 X better than bleach!!!!! It's coloured water and has zero affect on stains! Don't waste your money, I'm gobsmacked they get away with conning people.

MISTAKINGLY I USED IT ON MY STAINLESS STEEL KITCHEN SINK AND IT HAS RUINED IT FOR GOOD. DON'T MISTAKE THIS FOR ORDINARY BLEACH

Whilst this stuff may be effective against limescale ,what marks a toilet the most ? Excretia , of course ,Harpic does no touch it ,even overnight ,where as good old household Bleach will eradicate it in two hours sometimes. Bleach retails at about 1£ a bottle ,plus you cna buy bleach with added limescale remover ,far better. Harpic and Toilet duck are a ridiculous scam in my opinion . Don't take my word for it , everybody's toilet gets marked with poop , do the test comparison for yourself .

The product works fine but the bottle is very slippery with wet hands. I have cut off the plastic sleeve which rather negates their advertising. If you drop a bottle of bleach we all know the consequences! Do they not test these things with wet hands, which we have a lot of the time when we are cleaning. I had gloves on but they were wet too.

This morning i cleaned the bathroom like normal. Squirted the toilet cleaner in the toilet bowel. Not thinking poured bleach over the seat. usually i do not at same time but was rushing. Then i got overwhelmed by fumes. Auto reaction is you take a breath. I took a breath of poisonous gas. Realising what i done. i flung the window open and flushed the Toilet. My chest has been tight since. However was tight for two days before. I just wanted to make people aware. Im 46 and was unaware this could happen> Please read the bottles and think before you use two chemicals together. On own great for keeping the limescale at bay. Never have limescale in my toilet

I used Harpic the other day and failed to notice that it had dripped onto my toilet seat.During the night it had burnt and eroded thet toilet seat. Now i am aware it is corrosive but it IS a toilet cleaner and it shouln be stated that if in contact with the seat then wipe immediately.Now i have to buy a new seat.

I have no qualms about the product, but the packaging is right over the top to make you think you have lots of the product. It does state there are 8 tablets in the pack but they are so small compared to the size of the box. I arranged the 8 tablets on a row at the bottom of the package and they lined up nicely in the depth of the package, so above this row of tablets is 60% of unfilled space. Not only that but with all that space to rattle around in the tablets do get broken. I took a photo of this (pity I can't show you) to prove the point to Harpic, so tried to log onto their website harpic.co.uk to email them with this photo - useless, try it !! So I could not even contact them. I can't stand companies who are not 'visible' As an ex-environmental employee I hate to see resources wasted. Total waste of space.

I have used this product in the past, but I can't for the life of me get the top off. I have 2 bottles and have the same problem with both. Does anyone else have the same problem? Really fed up and will try all tops in supermarket in future to see if I can get tops off. If I do get the top off I will leave it off, this then cancells the child safty aspect.

After trying different products to get rid of stains and limescale on my toilet bowl, I decided to give this a try and what a surprise.. it actually left my toilet looking like new. The smell is a bit strong, but it is bearable, I would definitely recommend this product.

This product is brilliant , i used this for the first time today and our toilet had very bad limescale all on the bottom of the inside and after 15minutes of leaving this product in the toilet the limescale just fell off i hardly had to do any scrubbing. Would definitely recommend this to friends and family. If ur toilets bad and you want to make it look new then this is the product for u.

lortet virker ikke og har man brugt flasken en gang virker spr jte effekten ikke mere - k ber aldrig det lort mere
