How to remove calcium deposits on exterior

Last week, I was watering a garden that sits next to my RV. The sprinkler was on for several hours and now, there is a white haze that coats the exterior of my Tioga Montara. What can I use to safely remove that haze without damaging the exterior of the motorhome?
Thanking you in advance for any suggestions.
