Powerful All Purpose Descaler, New Formula, Limescale Remover – Ideal for Kettles, Coffee Machines, Irons and Shower Heads, 3 Sachets x 6 (18 Sachets Total)

Works very well and fast! It has an odour when used; however, this cleans away easily. Very simple to use and leaves the kettle looking brand new!

I’ve used this product before on my electric kettle and am always happy with the result. Easy instructions to follow and perfect results every time. Just 8mins to clean even thick scaling. Highly recommend for performance and excellent price.

Great for kettles. Cleaned mine really well Simple instructions and minimal effort to clean

The decaler comes with 3 packets, and tge instructions are in colour which is always a bonus, and they are very easy to follow. The results were excellent within minutes of using and one packet did amazing results. I would definitely buy this again. Very good value for money.

Wow, its amazed. I used this product first time. I need clean inside the kettle. Its so clean & shiny. Best product. Its easy to used and understand the information. Take you under 30 minutes.

I swear by Oust it cleans my kettle like new each time and I hate to see scale build up at all . I haven’t used it in my iron as I only use distilled water on that . Very effective from the word go and descaling starts in seconds I haven’t used tried other but Oust for me and it’s really value for money Just follow the simple instructions and you can’t go wrong

Best value I've seen works well each box contains two sachets!

I agree with another review the instructions about letting the water cool for 10mins, it works much better if it is put into boiling water. Having said that if you have a kettle that is badly stained it takes more than one, I had a old kettle that hadn't been used for ages which I did consider throwing out, it took three sachets before it was cleaned, but it did come up very clean in the end. Even the kettle I use every day and is cleaned regularly and was not badly stained still took two sachets.
