    Abstract: A substrate processing method includes a polymer-containing liquid supplying step of supplying, to a major surface of a substrate, a polymer-containing liquid that contains an acidic polymer and a solvent dissolving the acidic polymer, a polymer film forming step of rotating the substrate with the polymer-containing liquid adhered to the major surface to spreadingly coat the polymer-containing liquid and form a polymer film, containing the acidic polymer, on the major surface of the substrate, and a rinsing step of supplying, to the major surface of the substrate, a rinse liquid that cleans the major surface of the substrate in a state in which the polymer film is formed on the major surface.

    Abstract: An apparatus and a method are provided for an air filter cleaning wand for flushing contaminants from an intake air filter of an automobile engine. The air filter cleaning wand comprises a proximal flange, a conduit, and a distal end portion. The proximal flange is configured to receive a nozzle of a water hose. An interior of the conduit is in fluid communication with the proximal flange. The distal end portion comprises a plurality of longitudinally aligned vents in fluid communication with the interior of the conduit. Upon passing water through the water hose and into the conduit, pressurized water streams exit the vents along the distal end portion so as to flush contaminants from the air filter. The air filter cleaning wand advantageously is comprised of a material which is sufficiently durable and temperature resistant to retain its configuration during operation when coupled to pressurized water sources.
