Dishwasher & Washing Machine Descaler - 2 x 75g Sachets

Great product, works really well. I use 2/3 sachets in the kettle but our water is very hard

Have been unable to find these in any store. Only the lighter oust in shops. I am about to buy more. Especially good for hardwater areas.

Good product. Bought for my washing machine as I can’t get my regular one. Bit pricey but did the job. Just opened sachet and poured in drum.

Fast Delivery Product was excellent to use. Would Purchase Again

Have used similar brands for years and switched to this brand when old one no longer available. Hard to know how well these things work unless you want to open up the machine, but certainly it smells fresh and clean after use.

I used to purchase this Oust product many years ago to descale (remove limescale) from my washing machine. I was always very happy with results. Unfortunately several years ago it seemed to completely disappear from all retail outlets that i used to buy it from and i have never been able to locate it again until now on Amazon. Six boxes with 2 sachets in each box for £12 & free delivery is one of the best bargains i've ever had. It used to cost me more than £2 a box all those years ago from Tesco. I couldn't be more pleased with this transaction & i will definately be ordering again at a future date.

This is an awesome product; I had used the kettle descaler before and worked really well, so after moving in to a new rented flat and noticing the washing machine seemed to be all stained inside and in not very good condition in general, I used this and it actually left the tumble looking as good as new - really it is so so shiny now. And the washing machine liquid cleaning product couldn't even make it shine like that, so I am genuinely impressed. 10/10 product - would 100% recommend.

I live in a very hard water area (300+ mg/l CaCO3) and have been using Calgon tablets with every wash for 10+ years with this washing machine. I recently purchased an endoscope and thought why not take a look at the washing machine's condition? The pictures were horrifying! So straight to amazon to look for the best descaler and purchased this 12 pack of Oust. After the first application, still considerable scale, although the heating elements were looking slightly better (see photo). After a second application, the scale is slowly receding, but still a considerable amount. I think I am going to have to use all 12 before I get the machine back in a good scale free condition. Would recommend, but expect to use multiple times to really remove any hidden build up of scale.
