One more thing. You may be left with etched marks in the paint after the bath. The white minerals may be gone but what happen it that the calcium, magnesium, etc act like little magnifying glasses and amplify the suns rays. Depending how long the minerals have been sitting there will determine the severity of the etching. Don't worry, use a good abrasive based polish like Menzerna Intensive Polish and those marks with disappear. Follow up with Final Finish and you will be ready for waxing and showing off you shiny paint.
If you have any other questions don't hesitate to ask.
