Abstract: A system and a method are disclosed for controlling structural deterioration of a vehicle parking structure by arresting deterioration caused by road salt erosion and corrosion of concrete floors and reinforcing steel in that structure. The invention includes spray washing the underside of vehicles prior to entry into the parking structure to remove road salt and thereby reduce road salt corrosive action within the facility. The invention further comprises arresting corrosion due to road salt which already has penetrated the concrete floors within the parking structure by the application of a chemical detergent which neutralizes the road salt that previously has penetrated the concrete. The chemical detergent may include a material having galvanic characteristics, such as metallic particles, which are believed to aid in inhibiting corrosion of the reinforcing steel.
