OUST Dishwasher & Washing Machine Descaler, Pack of 6 X 2 SATCHETS, 75G

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 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.

Just ideal for doing a kettle; not sure how many packets you'd need to do something bigger but the process always leaves me satisfied with the results.
