MDOT is one of the heaviest salt-using transportation departments in the country. Salt aerosol from the roadways deposits on ground-floor glass within a quarter-mile of any plowed road and corrodes aluminum and steel sash hardware over time. Slush splatter from passing traffic coats the lower third of ground-floor glass on every house within thirty feet of a curb. The post-winter call is the entire residential spring season here.
The Woodward, Telegraph, M-59, and I-696 corridors accumulate a distinctive black-brown film from brake dust, tire wear, and engine particulate that is heavier in the Detroit metro than in most other US metros at the same traffic volumes. The film is particularly visible on white-trim window frames and on ground-floor commercial glass along the major surface arteries.
