Abstract: An apparatus and method for cleaning a surface comprising a gas dispensing conduit having a first end connectable to a source of pressurized gas and an open second end such that a stream of pressurized gas may be dispensed from the open second end of the gas dispensing conduit. A liquid dispensing conduit is connectable to a source of liquid and associated with the gas dispensing conduit in such a way that liquid is introduced into the stream of pressurized gas wherein the liquid dispensing conduit allows liquid to be introduced into the stream of pressurized gas at a rate that causes the liquid to contact the surface to be cleaned while substantially preventing the liquid from running off the surface.
