We introduce a surface cleaning technique called two-fluid jet method, which employs gas and liquid mixture. With this technique, droplets are accelerated by high-speed gas flow, and sprayed on a target surface. The detail of droplet impacts and the mechanisms of cleaning are discussed. Especially splash formations after droplet impact are focused. In addition, the effects of surrounding gas species on the splash formation are discussed.
