– Powerful All Purpose Descaler, New Formula, Limescale Remover – Optimal for Kettles, Coffee Machines, Irons and Shower Heads, 18 pack, unscented

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

This is the best kettle descaler I have tried. I have used many other brands & also white vinegar but the results were disappointing. Oust is the only brand that has completely cleared the scale. I did use 2 sachets as the build up was quite bad. From now on I'll only need to use 1. I will definitely keep using Oust & recommend it wholeheartedly.

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.

Used monthly to descale a kettle. Easy to use. Always clears limescale and no noxious smell or taste in the kettle if used as instructed.

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

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.

Cleaned our kettle perfectly! Very easy to use.

disappointing result, applied it to my steam iron, partially cleaned the rust limescale but had to flush the dirty water few times and still soiled my ironed clothes afterwards. besides, i got the same results using home recipes like white vinegar so as far as i am concerned, product is ove-rated.

I bought this product for my glass tea kettle. We have hard water where we are and leaves marks on the bottom of the kettle, one packet cleaned the inside of the kettle perfectly.

Would not recommend this

It really bettered the interior of my dirty kettle. Limescale has greatly diminished on the first try, but wasn't all gone. Will continue using it until everything's squeaky clean.
