This cleaning method is characterized in that, with respect to a substrate to be treated to which a resist film has adhered onto the substrate or a substrate to be treated to which the surface thereof has been contaminated with a metal or metal compounds, the resist film is peeled off or the metals or metal compounds are removed by spraying onto the substrate to be treated a treatment solution containing gaseous micro/nano-bubbles and having a temperature maintained at 30° C. to 90° C., the mean particle size of the micro/nano-bubbles when measured by an ice embedding method using a cryo-transmission electron microscope being 100 nm or smaller, preferably 30 nm or smaller, and also preferably the density of such bubbles being 108 or more bubbles per 1 mL.
