The invention relates to a fast method for assisting daily stain removal. The fast method is characterized by comprising the following steps: inserting fabric with stains into a discharge space, and directly treating the stains on the fabric through plasma by adopting a dielectric barrier discharge method, wherein the discharge time is 30-200s, a power supply of 1-100kHz is used, the power of the power supply is 5-20w, and the discharge gas is a mixture of Ar and O2 or a mixture of Ar and air. The fast method has the beneficial effects as follows: through auxiliary clothes washing by virtue of the plasma, the hydrophilicity of the stains is effectively improved, the color of colored stains is removed or reduced, and the infiltration time of the stained fabric is reduced, so that the using amounts of a detergent and a dry cleaning agent are reduced, waste of water and energy are reduced, and the washing efficiency is improved.
