PROBLEM TO BE SOLVED: To provide an outstanding cleaning method of a glass plane which can cleanly finish the glass plane even if work such as wiping off is not performed after spraying a washing agent. SOLUTION: The cleaning method of the glass plane includes: the process of spraying the washing agent, consisting of a surfactant containing liquid in the form of a very fine particle having the mean particle size of 100μm or less, to make it adhere to the glass plane; the process of making the washing agent in the form of a very fine particle, which adheres to the glass plane, fall by self-weight without wiping off; and the process of removing the washing agent, which has fallen, in the lower part of the glass plane.
