To provide a cleaning liquid capable of keeping high-concentration gas stably in a liquid over a long period and exhibiting high cleaning performance.
In the cleaning liquid, nano-size gas bubbles exist in a saturation solution of the gas. The cleaning liquid comprises a liquid formed of molecules forming a hydrogen bond, and the distance of hydrogen bond of molecules in the interface between the liquid and the bubbles is shorter than that of the hydrogen bond in a liquid at ordinary temperature and pressure. By controlling a pressure change, a temperature change, shock waves, ultrasonic waves, infrared rays, and vibration, the bubbles in the cleaning liquid are collapsed for cleaning. The cleaning liquid is produced by a cleaning liquid production device including a gas supplying part 2, a gas-liquid mixing part 3, a gas separating part 4, and a pressure reducing part 5.
