Since the problem of residual ions or organic matter remains after washing has appeared as a cause of various defects in the manufacturing of display devices, it is very necessary to study a cleaning composition that can solve these problems.

On the other hand, Japanese Patent Application Laid-Open No. 5-271699 uses quaternary ammonium hydroxide as a main agent to solve the problem of metal impurity contamination by alkali metals, and does not include metal ions containing a nonionic surfactant and alkanol. Disclosed is a detergent composition for basic glass used for washing an optical glass or a liquid crystal glass substrate, and Japanese Patent Laid-Open No. 2000-319699 discloses a quaternary ammonium carbonate and a quaternary ammonium hydroxide as main components and a pH adjusting agent.
