2. Water softening - Wikipedia

   en.wikipedia.org/wiki/Water_softening

   Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes

3. Dealkalization of water - Wikipedia

   en.wikipedia.org/wiki/Dealkalization_of_water

   Chloride cycle dealkalizers operate similar to sodium cycle cation water softeners. Like water softeners, dealkalizers contain ion-exchange resins that are regenerated with a concentrated salt solution - NaCl. In the case of a water softener, the cation exchange resin is exchanging sodium (the Na + ion of NaCl) for hardness minerals such as ...

4. Cleaning agent - Wikipedia

   en.wikipedia.org/wiki/Cleaning_agent

   Purposes of cleaning agents include health, beauty, removing offensive odors, and avoiding the spread of dirt and contaminants to oneself and others. Some cleaning agents can kill bacteria (e.g. door handle bacteria, as well as bacteria on worktops and other metallic surfaces) and clean at the same time. Others, called degreasers, contain ...

   Even though liquid detergents can contain mostly water, they still have the volume advantage for surfactants and enzymes — the stuff that makes soap work. However, the disparity in performance ...

6. Sodium sesquicarbonate - Wikipedia

   en.wikipedia.org/wiki/Sodium_sesquicarbonate

   It is also used as a precipitating water softener, which combines with hard water minerals (calcium- and magnesium-based minerals) to form an insoluble precipitate, removing these hardness minerals from the water. [5] It is the carbonate moiety which forms the precipitate, the bicarbonate being included to moderate the material's alkalinity.
