The GM corridor industrial dust: Oshawa's General Motors assembly plant and surrounding industrial area along the 401 between Stevenson and Ritson generate fine particulate that settles on homes across south and central Oshawa. This industrial film is different from regular dust — it contains metallic particles and hydrocarbons that bond to glass. Standard squeegee cleaning doesn't fully remove it. Purified water with proper cleaning solution is the only way to break down industrial film. If you're south of Taunton Road, your windows are affected. Oshawa service hub →
