Toilet DESCALER HEAVY DUTY Limescale Remover for Toilet Concentrated Cleaner Formula Remove All Stubborn Stains CalSolve - Dissolve Urine Scale Destroys Smell 16x Doses 300 Grams

irstly, don't be fooled by these images on their sites. Not as big as you think you're getting, but........ results are magnificent. I tried the 30/60 minute use first. Saw that the limescale was starting to clear, so I gave the 24hrs a try and there is the results needed. PONG.... yip, it gives off a good stench. Very easy to use, I used the boiled water option and made sure before I poured, no cold water in the bends...... bailed out the water. After 24hrs, the toilet was lovely and clean, apart from a strip of scale that I poked with a screw driver and it all broke up. I then used more on a 30 min cycle and this time I was really pleased as every bit of limescale was now gone.

Best toilet descaler and cleaner I have used and pleased it is manufactured in the UK.

We live in the South in a very hard water area so our toilet often needs a good clean due to the limescale that builds up. This product is easy to use. Firstly, I boil a filled kettle and put the boiled water down the loo. I do this twice and then I put an amount of this in the water, stir it in the water and leave it overnight. It really works. The only negative comment I would have is that the container is tiny and also a funny shape. (See photo.) Quite difficult to get a spoon in the container. The last time I ordered this product the tub that came was huge and lasted me ages so I was quite surprised when this very small container arrived. Maybe they are saving on packaging? The product is expensive but does work.

This product is amazing, you activate it with boiling water. After a few hours, it cleared 4 years worth of brown stains from the toilet pan, without effort. I highly recommend this product and will be buying again.

Took a while to realise it and brave a review. BUT - this is just an expensive way to but soda crystals. Sorry!

Useless ended up putting 10 down the toilet and still didn't work might as well just flush. Five pound note down

First, some background: I had no issues with toilet staining until I started using a reasonably popular rim block product which left what I thought at the time was some sediment... I realised at some point that said 'sediment' was not actually being flushed away and then almost overnight, it turned into this really unpleasant massive brown stain around the bottom of the pan under the waterline. I tried your basics like bleach with limescale remover, cola, scrubbed it etc and all that happened was that it got worse. I could not have made it up! It started really stressing me out because I could not get rid of it. As a last ditch attempt before trying to drain the toilet and get right in there with a pumice stone, I did a search for an industrial product and this turned up. I thought a tenner was worth the risk and so I bought it. Be warned, this container only contains 8 doses if you are using it to keep stains at bay fortnightly as the packet says; otherwise, for heavy staining, it seems to be one dose. In any case, I used it all because by this point, the staining was pretty industrial and I was prepared to do almost anything to get rid! I boiled my kettle and poured the contents into the toilet, followed by the powder, stirred it around and left it overnight {from about 11:30pm - 8:45am}. I lifted the lid in the morning and the stain still appeared to be exactly as it had been other than a slight discolouration of the water. I was absolutely gutted because I thought it had been as useless as everything else I had tried... Thinking I was just going to have to get in there with a pumice stone and utterly disheartened, I flushed the chain... Imagine my amazement when the bowl completely cleared...! There was a tiny bit of residue left which I used the brush on a bit half-heartedly but even that lifted... I am so pleased with this product. Yes, it's expensive but in my opinion, well worth the money. The container is a stupid shape however, that just means it fits through the letterbox so I don't really mind that... Thank you, CalSolve, thank you!! UPDATE 07/11/23 Well the scale stain returned so I thought I would experiment with the CalSolve and just used the 2 teaspoons or so. I am delighted to report that it worked a treat. So I will continue to use it as directed :)

Worked really well on a heavily scaled toilet pan. Tried a double dose at first on our worst toilet and it did not magically fix the scaling so was disappointed. A couple of weeks later I was wondering what to do withithe rest of it and that unsightly U bend. I tipped the rest of the pack all in after using hot water as described in the instructions and the morning after using a glove tried cleaning the U bend with a washing up sponge scourer and it all lifted straight off. It looks as good as new again. Much better than fitting a new toilet. I will be buying some more
