Corrosion Investigation of Auto Surfaces and Professional Washing of Auto Paint Surfaces

This project was initiated to determine the effect of regular Car washings upon the retardation of corrosion on automobiles. A periodic problem is present in northern climates where, during the winter months, roads are often laden with salt to prevent icing of the streets. Some of the salt will become deposited on the car with accompanying possible corrosion problems. Furthermore, when the vehicle is taken to a commercial car wash establishment, the salt will become incorporated in the recycled water to be used in washing of other cars. Whether this chloride content build-up in reclaim water in northern car washes is significant needs to be determined. Thus, there are two sources where corrosion is a potential problem.
