A multi-stage brushless car wash system is disclosed. The multi-stage brushless car wash system includes an electrical separation system stage, a first wash stage, and a second wash stage that are independently controlled to wash an exterior of a vehicle. The electrical separation system stage generates an electrical potential on a surface of the vehicle. The electrical potential is greater than a zeta potential of road film thereby aiding in the removal of road film in the multi-stage brushless car wash system. The electrical separation system stage applies a plurality of different electrically charged chemical solutions onto the vehicle to generate the electrical potential. The chemical solutions may include at least one of an alkaline based solution or an acid based solution.

A washing device and system is herein disclosed. The washing device includes a washing tub, a shaking assembly, a plate bracket, a first plate, a second plate, and a controller. The shaking assembly is mounted at a lower end of the washing tub. The plate bracket is mounted on the shaking system. The first plate defines a first set of holes and is movably mounted to a first side of the plate bracket. The second plate defines a second set of holes and is movably mounted to a second side of the plate bracket. The controller is operable to selectively activate and control the shaking assembly. In use, the first plate and the second plate support a smoking device therebetween, with cleaning fluid being agitated via the shaking system to clean the smoking device.

Many conveying units for media capable of flow are used for products that are harmful to the environment and at least attack the conveying units themselves over time or deposit in them and clog them. Cleaning of the conveying units is therefore recommended, but such cleaning represents an effort that is preferably not made, because of the effort involved. Against this background, an apparatus for cleaning of conveying units, which apparatus can run both in simple manner and practically without supervision, uses a cleaning circuit in which the conveying unit to be cleaned is short-circuited with a cleaning agent tank and thereby constant circulation of cleaning agent through the conveying unit to be cleaned is pumped and the unit is thereby cleaned.

A reticle cleaning system includes a casing, a reticle holder, and a static charge reducing device. The reticle holder is in the casing and configured to hold a reticle. The static charge reducing device is above the reticle holder and includes a fluid generator, an ionizer, and a static charge sensor. The fluid generator is configured to control a humidity condition in the casing. The ionizer is configured to provide ionized air molecules to the reticle. The static charge sensor is configured to detect a static charge value on the reticle, wherein the ionizer is between the fluid generator and the static charge sensor.

Disclosed is a method for liquid-treating a substrate. In a method for treating a substrate, the substrate may be treated by supplying a treatment liquid onto the rotating substrate by using a first nozzle and a second nozzle, the first nozzle supplies the treatment liquid to an area including a central area on the substrate, and the second nozzle supplies the treatment liquid to a peripheral area of the substrate.

An apparatus and a method of washing (or pre-washing) silverware/flatware, or one or more other objects/parts is provided. The apparatus and method utilizes a fluid-push/pull pumping system and method in which generally an entire volume of fluid is pushed or pulled through a cavity of a housing in which the silverware/flatware or other objects/parts are located. The housing is configured to hold a mass of silverware or other item(s) within the cavity. The pumping system is configured to pump generally an entire volume of fluid is out of the cavity, and to direct the pumped fluid back into the cavity to create a generally continuous flow of generally an entire volume of fluid through the cavity, thereby causing the fluid to flow through the mass of silverware or other item(s).

Cleaning articles including a heat engine incorporated therein. The cleaning article may include a substrate (e.g., a non-woven wipe) including one or more layers. The heat engine may be in the wipe or pad, and includes a reactive metal composition which upon contact with a salt water (e.g., saline) composition, reacts to produce heat. The cleaning article may thus produce water vapor and/or steam upon activation of the heat engine. A venting structure may be provided adjacent to or surrounding the heat engine that includes an impermeable material (e.g., impermeable to water and/or air or other gas), which includes one or more vents through the impermeable material. The venting structure directs water vapor and/or steam to a desired face of the cleaning article, away from the user. A heat barrier layer may insulate a user's hand from the generated heat, and/or a handle may be attachable to the pad.
