Considering a de-ionized car wash kit for the final rinse to greatly reduce water spots.
I'd like something mobile on a cart preferably - ease of moving around is my intent.
I haven't found much out there except the two below, they aren't cheap, nor are replacing the filters/resin which concerns me on how long they will truly last until the filter/resin is depleted. I like that they both have a TDS meter/sensor.
What have others found that work?
