All Purpose Descaler Environmentally Friendly CalSolve Limescale Remover Cleaner for Kettles Toilets Coffee Machines Concentrated Formula 200 Grams

Update - review was based on 600g container. Now a much smaller container so no longer the same value.I'm a bit obsessive when it comes to any scale on products. My water is softened in my house, but obviously not drinking water. Over the years I've spent a small fortune on descaling products which usually take a while to react, give off noxious fumes and seem to remain in the appliance even after many rinses.I found this last week after a long search and attracted by the price placed my order. A few days later package arrived and pleasantly surprised by the excellent packaging. The tub is very well security sealed and then has an inner lid to keep moisture out and avoid spills. Inside there is a small scoop and obviously the product which is a powder not tablet which is fine as it dissolves quicker.My main scale magnet is my De'Longhi espresso machine. Which gets really noisy when it's due a clean. I added 500ml of water and 2 scoops of product to the reservoir and turned on. Allowing approx half of the water to run through into a jug, I then poured this into my kettle. Within approx 30 seconds the bottom of my kettle was shiny again.Now what amazed me was, there is very little smell. I got some on my hands it didn't burn (which Oust does)So I left my espresso machine for 30 mins, ran through again till the full 500ml was used then rinsed twice.I made an espresso which came through lovely. Now usually after descaling I can taste the acid. This time nothing, just coffee.So works very well, no smell or residue, cost effective, safe(er)than other products. And finally easy to dispense, so cleaner to use.I've already recommended this to friends and family and will continue to.

Descaling a kettle is easy with this product and effective. My only qualm is that I refill and boil the kettle a couple of times before using for tea; and in that time I can see lime scale already building up in the kettle!!

Works extremely well - probably the quickest and easiest kettle cleaner I have used. Be warned however, follow the instructions PRECISELY. I ruined my first kettle by not following the instructions - my fault entirely - as I bought exactly the same new kettle and it has kept it completely clean ever since.I use it every few weeks roughly, I'm in Scotland so water is likely not as bad as the rest of UK.I've had the same tub for a few years but I notice now the quantity is now not the same and supposedly the effectiveness has changed too. I am due a top up so will review it again when I buy and try the new version.

I was skeptical when I read the description of no acids, since traditional descalers very effectively use an acid to react with the limescale. You see the effervescence as it works, leaving a clean kettle behind but I was inspired by the description that it will “surpass ALL analogous products”.Some reviews stated “it does not work” some “it’s the best thing ever” so I took a chance as it looked affordable (if it worked) as you get many doses in a bottle. I agree now with the former: it does not work, at least not noticeably well. After following the instructions on the pack I was able to see a few flakes of scale lift from the base of the kettle. I repeated the application and used a larger quantity and a few more flakes lifted off. Despite the high temperature of the water and the concentration of the solution and leaving for several minutes to work, there was no more impact.A teaspoon of citric acid from the cupboard and 1boil later and the kettle is squeaky clean. I do not recommend this product.

I got this specially to try as an alternative to 'spirit of salt' (hydrochloric acid) to remove unsightly limescale stains from a toilet bowl. For anyone that does not know the only effective way to do that is with a fairly strong acid and on vitreous enamel like a toilet bowl which is basically a glass-like glaze on porcelain that is a safe thing to do as long as you wash the acid away with plenty of water afterwards and never, ever mix with anything else such as bleach which can result in poisonous chlorine gas being given off. 'Spirit of salt' is effective but it is a very hazardous chemical to handle so I though I would try something safer. I removed as much water as possible from the bowl and then added 2 litres of boiling hot water with the appropriate amount of CalSolve, 8 scoops. I left it for about an hour and gave it a good scrub before flushing well. It worked a treat. It had removed all the limescale staining leaving a sparking white bowl. I know it is not what the product is designed for but it does the job which I know is a problem for a lot of people and it is not an unduly risky or unpleasant product to use.

If I could give 1/2 stars then it would be 3.5. Definitely works but my kettle wasn’t that bad! However it took 2 attempts to clean it to what I call acceptable levels. However when I looked closely there were still some lime scale left so a third dose is required. I hate to think how many doses I need if my kettle was really bad!The other negative is that The instructions says use 1litre of water, add the dose of this stuff and then bring to boil. However, you are then left with the top half of the kettle still with lime scale! So you have to rinse the kettle around or take of the lid and somehow get spoon the water over the various parts and corners of the kettle that the water did not reach! You have to be very careful as you’re messing around with boiling water! I don’t know if you can add more water and up the dose, doesn’t say on the instructions!In summary, it does work but you have to give it a few goes, overall a bit disappointed though.

Last time I got this, it was 600g for £14.99. Now it is 200g for £7.99.I was expecting a bit of an increase but not this much. Interesting, the description still states 50 applications. I guess they have greatly reduced the resulting solution concentration which will affect the efficacy of the process.Whilst this product does work, I will find an alternative more cost effective descaler.
