Wind, spray and traffic film by the waterfront
Buildings close to the Hudson face steady wind that can drive grit and salt spray onto facades and entrances. Plazas around residential towers collect a dark film where cars, delivery trucks and pedestrians meet, and the stone, pavers and metal trim all respond differently to cleaning.
Further inland, older brownstones and brick rows suffer from soot and shade. Stoops, areaways and iron fences collect the same grime as their counterparts across the river. Sidewalks outside corner stores take gum, oil from vehicles and spilled drinks. We look at the material, the age and the exposure of each surface before we choose a method.
