Water softness are not deionizers. Mine does nothing for spots. im sure someone here can explain why
A water softener exchanges the hardness (mainly Calcium & Magnesium plus often iron) for salt (Sodium Chloride). The harder the water, the more salt will be in the outlet of the softener. When you rinse with the softened water, it will evaporate and leave the salt behind on the surface as spots.
To really have a spot free rinse, you need deionized water. This is a much more expensive method of water treatment and not something that is economical to do except for small quantities (i.e. an RO unit for drinking water).
Personally, I like the rainwater collection idea that one of the replies mentioned.
