The new method is intended for cleaning solid surfaces by delivery of a liquid through a cavitating nozzle. This method distinguishes from existing ones in that it involves chemical modification of actively cavitating vapor-gas cavities by feeding them with one or more reactive gases which thermodynamic properties allow them to react with each other or with liquid of the cavitating jet.

Different versions of the new method provide for employing water as the liquid; and ammonia as well as hydrogen chloride as the reactive gases; besides, carbonic acid may additionally be fed into the vapor-gas cavities.
