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.
