The average water system can be descaled in just 12 weeks. The first signs are when the water feels silkier. Many customers report softer skin and shinier hair. Many also notice that their skin is not itchy from eczema and clothes will wash better .

Scale starts to soften and fall off toilet cisterns and kettle elements. Scale on taps and shower heads will soften and can easily be scraped away. This limescale will not reform. There should be a progressive increase in hot water temperature and improvement in water flow.
