Disclosed is a portable and self-contained washing and sanitizing apparatus. The apparatus finds particular application in washing small baby items such as bottles, nipples, teething rings or toys. However, the apparatus can likewise be used to clean dishware, glassware, or utensils. The apparatus includes a container with a lid, the container housing the items to be washed; an accessory holder connected to the lid for holding accessories during washing operations; a water reservoir for storing and collecting wash water; and a housing for interconnecting the container and reservoir.

Provided is a substrate treating apparatus comprising: a support unit for supporting the substrate; a discharge unit for discharging an organic solvent to the substrate supported on the support unit; and a solvent supply unit for supplying the organic solvent in a liquid state to the discharge unit at atmospheric pressure to a temperature higher than the boiling point of the organic solvent.

A process for cleaning an object, such as for instance an outdoor playground structure or other communal object, includes applying a degreaser solution to a surface of the object. The surface is also power washed using water at or above ambient temperature, and additionally steam is applied to the surface. A disinfectant solution is applied to the surface, and if a final contaminant level of the surface is below a predetermined threshold value then finally an antimicrobial product is applied. The process removes contaminants including microorganisms and organic residues and provides a surface that remains resistant to recontamination for an extended period of time.

The invention relates to a device for cleaning the pipes of the drinking water circuit of an aircraft, in which the device is independent of the aircraft and is connected to the circuit intermittently and supplied with liquid. The device is characterized in that it comprises a mobile chassis supporting a plurality of functional sub-assemblies required to produce a hot liquid, including a closed-furnace gas condensing boiler. The invention can be used to clean the pipes of aircraft.

A liquid heating method and apparatus including a heat device 7 having a flow passage member forming a tubular flow passage for passing a sulfuric acid solution, a heater arranged on an outside of at least one of opposing flow passage surfaces of the tubular flow passage, a liquid draining line 10, an atmosphere opening line 12, valves 11 and 13, a liquid draining mechanism for draining the sulfuric acid solution heated at least in a heat receiving area between the opposing liquid flow passage surfaces of the tubular flow passage, a flow meter 6 for measuring a flow rate of the sulfuric acid solution, and a control unit 14 responsive to the flow meter 6 for determining a defective liquid flow in the tubular flow passage and for draining the sulfuric acid solution using the liquid draining mechanism.

Embodiments of the present disclosure generally relate to methods for detecting end-points of cleaning processes for aerospace components containing corrosion. The method includes exposing the aerospace component to a first solvent, exposing the aerospace component to a first water rinse, and analyzing a first aliquot of the first water rinse by absorbance spectroscopy to determine an intermediate solute concentration in the first aliquot, where the intermediate solute concentration is greater than a reference solute concentration. The method further includes exposing the aerospace component to an aqueous cleaning solution to remove corrosion from the aluminum oxide layer, exposing the aerospace component to a second solvent, and exposing the aerospace component to a second water rinse, and analyzing a second aliquot of the second water rinse by absorbance spectroscopy to determine a post-clean solute concentration in the second aliquot, where the post-clean solute concentration is less than the intermediate solute concentration.

The present invention provides a system and method for cleaning and disinfecting shopping carts. The system comprises a main housing with three main systems: a steam system, an ultraviolet system and a microwave system. The combination of the systems allows for the reduction of germs and viruses without the use of chemicals which may be both harmful to the shopping carts and to the environment. A conveying means allows shopping carts to be displaced through the system. The system further provides a disinfecting box in connection with the main housing for users to disinfect their hands. The method provided allows for the cleaning and disinfecting of a shopping cart with the use of the system.

The present invention provides techniques to more accurately control the process performance of treatments in which microelectronic substrates are treated by pressurized fluids that are sprayed onto the substrates in a vacuum process chamber. control strategies are used that adjust mass flow rate responsive to pressure readings in order to hold the pressure of a pressurized feed constant. In these embodiments, the mass flow rate will tend to vary in order to maintain pressure uniformity.

A method of operating a cleaning system removes support material from parts made by a three-dimensional printer. The method operates the cleaning system to correlate data for features on a part located within a receptacle with structural data in a file used by the three-dimensional printer to fabricate the part. The method then operates one or more actuators to locate a fluid directing nozzle pneumatically connected to a pressurized fluid source opposite areas containing support material and operates the pressurized fluid source to enable pressurized fluid to be directed by the fluid directing nozzle at the support material. The method includes generating image data of the cleaned areas with an image sensor so the removal of the support material can be confirmed, and if an area is not sufficiently cleaned, the cleaning operation can be repeated.

Caustic-free detergent compositions are provided. Detergent compositions including an aminocarboxylate, water conditioning agent, non-caustic source of alkalinity and water beneficially do not require the use of additional surfactants and/or polymers to provide suitable detergency and prevent scale build-up on treated surfaces and enhance protein removal from the treated surfaces. Beneficially the detergent compositions have a concentrate pH less than about 11.5. The detergent compositions are used with a sanitizer to employ the low alkaline detergent compositions are particularly suitable for use as low temperature ware wash detergents that beneficially reduce scale build-up. Methods of employing the low alkaline detergent compositions are also provided.
