Water softeners do not make spot free water; can you believe it?
Hard water minerals, mostly calcium and magnesium, will leave white colored spots on surfaces where water is left to evaporate. If you buy a water softener to because you don’t want to have hard water white spots anymore you will be disappointed. Water softeners do not prevent white spots. This happens regardless of whether your softener uses ion bonding or ion exchange technology. You might be asking yourself why water softeners don’t produce spot free water.
Let’s take a look at the two technologies a little more in depth.
Ion Bond Softeners:
The white spots left behind are the hard water minerals bound with Polyhalt®. This spot is the Polyhalt® / hardness complex that simply wipes up with little effort. The treated minerals do not “stick” to surfaces.
Ion Exchange Softeners:
Ion exchange softeners exchange salt for hardness minerals in the water. The whits spots left behind are salt. Just like ion bond softening the spots simply wipe up and minerals do not stick to surfaces.
Because softeners leave white spots you might be wondering why soften your water. As you can see, when it comes to white spots, the real benefits of softened water are the reduced effort required to clean up the spots and keep your home looking its best.
