An object of the present invention is to provide a cleaning agent and a cleaning method capable of effectively removing scale stains of a hydrophilic film used for an anti-fog glass, an anti-fog mirror and the like, and adhering contaminants which make the coating water repellent. An aqueous cleaning agent capable of removing adherent contaminants due to a binding silicon oxide compound adhered on a hydrophilic film and adherent contaminants that make the film water-repellent. It has an oxidizing agent capable of oxidatively decomposing the silicon oxide compound, and appropriately has an anionic surfactant, a water-soluble organic solvent, a basic substance, and a metal chelate.
