Water de-minerizer?

[mark989]

Does anybody use a water de-mineriser when washing their car. An inline one that connects to the hose pipe. If so are they worth it? as i live in a hard water area and it always leaves streaks when washing the car.

Any recommended ones would be greatly appreciated.

Thanks,
Mark
