Review: descaler is excellent - Best toilet descaler and cleaner I have used and pleased it is manufactured in the UK.
Review: I wish I had taken a 'before and after' shot! - 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 :)

## Questions & Answers

**Q: Can this be used on a Thetford plastic toilet cassette**
A: If the plastic toilet cassette can withstand very hot water, then I would say yes.

**Q: Can this be used in the toilet cistern?**
A: I have only used in the toilet pan itself with some hot water. I does work ok, if heavy stains you may need to repeat. I don't believe that it is made for use in the cistern as it cleans at source rather than via flush.

**Q: Is this product safe to use with a septic tank?**
A: How small is your tank compared with the pan in your toilet?

I am not an expert but we used about a box of the cleaner on each of two thirty year old toilets that were looking grubby. Now we put about a table spoon in once a month. I cannot think that quantity can do any harm to a septic tank. It is not that the powder fizzes when you put it in the water like some of these drain cleaners do - or did as some of them are illegal now!

**Q: I thought i would get a dilution chart,i cant be the same for a full descale of toilet overnight and say the shower hise head, can it ?**
A: Just follow the instructions - it works!

### ⭐⭐⭐⭐ Works but a tiny container!
*by M***E on 28 December 2021*

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.
