Spots on car?

  • Oily spots on vehicle surface –
    • Too much drying agent applied to vehicle
    • Incomplete rinse by spot-free water
  • Powdery spots on vehicle surface
    • Water Quality – hard water leaves white spots after drying due to mineral content in water. Test water and adjust or replace water softener.
    • Too much soap being used or not properly rinsed will react with drying agent and may form a powdery white residue.
