Oust Powerful All Purpose Descaler, Limescale Remover – Ideal for Kettles, Coffee Machines, Irons and Shower Heads (1 x 3 Sachets)

This is my go to product when it comes to descaling my kettle.Was able to buy this packet of 3 descalers for £1. So very good value for money.Super easy to use.Boil your kettle 1st, I then place my kettle in the sink and very slowly pour in one of the liquid sachets. Be aware, you need to add the sachet slowly because otherwise the product reacts to the hot water and the kettle will be a over flowing mess of bubbles.I let the solution stand for 10 minutes, pour out the solution, rinse my kettle and then boil my kettle several times afterwards.Each time discarding of the hot water, rinsing, and adding fresh water to boil again.Kettle is left spotless with no traces of limescale left behind.Brilliant product that I will always buy for my kettle.

This product is very good for dissolving limescale in my kettle, no denying that. The last time I purchased it, in 2021, a pack of 3 sachets cost £4.10. But now, although the individual pack price has decreased - minimum 2 x 3 sachet packs @ £1.40, there is added postage of £19.99. Presumably it is being sent from overseas. So the price for 2 packs x 3 sachets is £21.39. A good way to lose customers, I will be buying something else. A shame, because this is a good product.

I use this to descale my kettle every 2 months. It is easy to use, just follow few simple steps on the instructions, it doesn’t leave any smell afterwards and it is value for money. The only pitfalls is that you can’t fill the kettle full during descale process, or the water will spill, which mean this leave the top part of the kettle unable to be descaled at the same time. Otherwise it will be given 5 stars.

Very Easy to use !!!Did a Super Job at Cleaning the inside of my Kettle.FILL KETTLE HALF FULL.BOIL KETTLE.POUR THE CONTENT OF THE PACKET INTO KETTLE.WAIT 10 -15 MINS .IT GETS RID OF LIME SCALE BUILD UP SUPER GREAT 👌👍.KETTLE LIKE NEW NOW 🙂RINSE KETTLE OUT AFTER THE SOLUTION HAS DONE THE JOB & RE FILL KETTLE WITH COLD WATER AND BOIL AGAIN THEN POUR OUT & RINSE AGAIN 👍I BOILED MINE TWICE WITH CLEAN WATER & POURED OUT EACH TIME JUST TO BE SURE THE SOLUTION WAS OUT OF KETTLE !!!ITS SUCH A GOOD FEELING WHEN YOU ACTUALLY BUY SOMETHING THAT WORKS 😊THIS STUFF IS Bloody GOOD !!!I WOULD DEFINITELY RECOMMEND THIS PRODUCT TO ANYONE.

I have tried various products and different methods to periodically clean and descale my kettle and steam-iron. Oust is the best product I have used over the years, and I keep returning to it.I find it simple to use, and extremely effective.The instructions for use are clear and set out in detail on each pouch of liquid.Note that with a steam iron, you heat the iron before you add the Oust and do not reheat it or you could have clouds of "oust steam" in the room. Only use it on your steam iron if the Instructions say that you can - some irons have special cartridges and should not be descaled with something like Oust.I have tried different products, but I find Oust the most effective.

I love this product so much! It’s so easy to use and comes with clear instructions on each packet for the product you want to use it for, iron, kettle, coffee machine etc. it’s super cheaper and does a great job at clearing the scale away. I was hesitant to try at first due to the price but now I wouldn’t use anything else.

Used two of these inside our kettle which had a small build up of limescale on it. This was making the tea and coffee have a funny taste so used two packs of these into half filled, freshly boiled water and left it for 15 minutes. Had tried one at first but didn’t lift the stains so used another one and after another 10 minutes or so, came back and the kettle was truely sparkeling inside like brand new. Brilliant stuff.Rinsed the kettle thoroughly and threw the first boiled kettle full away, then after that kettle was perfect with 0 funny or after taste etc.

It's a good product and works well but full of chemicals ... buy citric acid instead.
