Working well with our super hard water
In our small second place, which is a condo in the city, and in which the way the water is shared single meter, we have no way to put in a water softener. We have river sourced water in a 100-year-old distribution system, which is among the hardest type of water typical of city water systems. Our washing machine requires 2x  detergent. Calcium deposits kill our faucets, toilet mechanics, and water heaters prematurely. Glass doors of our showers get cloudy. And of course our  dishwasher, without max setting of rinse aid, and unless using specialized hardwater detergent leaves the dishes, and especially glasses and utensils with serious hard water spots.<br />We have been using another quite expensive per pod specialized hardwater dishwasher detergent and it is ok. But this Finish "Quantum" works as well, or better, at a lower cost.<br />Give it a try.
