Dishwashers for Hard Water – Buyer’s Guide

Hard water.

The two words that turn any homeowner white-haired with concern. This high mineral content leaves stony sediment on plates, but more so, clogs up pipes and small apertures. As such, you can either buy into all the accessories, special liquids, and unusual home remedies, or you can invest in a machine that is designed to handle hard water as part of its repertoire of functionality.

Mind you, I personally always add the extras and the home remedies to these machines just to give them a little help. It’s sort of like giving a bodybuilder a shot of protein, helps overall performance.
In this article, I present you with the top 5 washing machines that work seamlessly and effortlessly with hard water.
