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

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

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.

This descaler does a good job and works well, but I do feel the old formula was better. It still removes limescale effectively, just not quite as powerfully as I remember. Fine for regular use, but I preferred the previous version.

Does the job well, been using this brand for a while, reasonably priced too.

Value pack and best descaler ever. It makes my kettle limescale free

The best. I use it once a week as our area has hard water. My kettle gets limescale buildup quickly. I use this and rinse, soft boil up to 6 times, and then I am ready to use my kettle. It is fast, easy to use, sachet contents are enough. I am not sure if it will last longer for you, but for me, it's a weekly thing. I rinse and soft boil it 6 times to remove the weird taste. It removes scale for a week at least and stains too.

Great , does the job in couple of mins definitely would recommend

Not as quick working as it promotes. I used 3 sachets to start with not quite half a kettle of water as build up was pretty bad. After 4 hours and roughly 7 reboils there was still some stubborn scale . So I emptied it out, put just enough water in the bottom to allow kettle to boil and used another sachet and after an hour it was sparkling clean. So next time I'm only going to cover the bottom of the kettle enough to allow it to boil as more concentrated solution works better

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.

Cleaned our kettle perfectly! Very easy to use.

Would not recommend this

Its excellent
