In such heavy traffic and low speeds, it is necessary to open the helmet window and vents to ventilate the helmet and remove the moisture inside.  Otherwise, intense evaporation may obstruct the driver's vision. In cases where steam lenses become dirty, they can be cleaned by dry wiping them with microfiber cloths available at opticians. If different substances are applied, the vapor glasses may lose their properties and become scratched.
