Abstract: To provide a method for cleaning a glass substrate in which aggravation of surface roughness of the glass substrate in alkali cleaning is suppressed and cleaning performance is improved. In one or a plurality of embodiments, this invention relates to a method for cleaning a glass substrate, including bringing a detergent composition into contact with a glass substrate to be cleaned. The detergent composition containing an amine including 1 to 10 nitrogen atoms and an inorganic alkali, the amine content is in a range of 5.00 mass % to 70.00 mass % relative to the total mass of components of the detergent composition other than water, the glass substrate to be cleaned is a crystallized glass substrate, and a pH of the detergent composition during cleaning is in a range of 9.00 to 11.50.
