Abstract

A method of removing a stain from a target object and an apparatus therefor are provided. The method comprises the steps of: placing a light source at a preset distance from the stain; illuminating the stain with light having a wavelength in the range of [400nm, 500nm] generated by the light source, wherein the light generated has a preset light intensity at the surface of the stain. With the illumination of the light source having a wavelength in the range of[400nm, 500nm], some stains, i.e. stains caused by food, can be removed from some target objects, i.e. fabrics.
