A cleaning solution for cleaning laboratory consumables comprises sodium percarbonate in a concentration of from 0.9% w/w to 1.6% w/w based on a total weight of the solution and at least one diluent to 100% w/w.

A knife cleaner for a commercial kitchen is mounted on a countertop or prep table with suction cups or similar devices, and provides three separate compartments for washing, rinsing, and sanitizing solutions. A removable cap provides a channel guide leading downward into each of the three compartments. The wash channel guide provides scrub brush components to remove food particles and other debris. The cleaner is disassembled easily without tools for cleaning purposes.

A beverage container washing system may utilize a through opening air knife to direct a flow of pressurized fluid through an opening in a concentric housing member of a beverage container washing system and onto a beverage container disposed within a wash chamber thereof.

A beverage container washing system may be used for rapid washing and/or sanitizing of beverage containers, e.g., for use in a retail environment to wash and/or sanitize customer-provided beverage containers prior to filling the beverage containers with purchased beverages, among other applications. Separate entrance and exit openings may be provided in some instances to minimize employee interaction with unwashed customer beverage containers, and a beverage container may be conveyed from the entrance opening to the exit opening past one or more stations using a holder that is capable of spinning the beverage container when the beverage container is disposed in at least one of the stations.

A sterilizing storage device may include a housing defining an interior chamber and having an opening defined in the housing to enable access to the interior chamber, the interior chamber divided into a plurality of storage compartments, each storage compartment of the plurality of storage compartments configured to slidably receive a carrier holding a plurality of laboratory consumables. A door may be affixed to the housing and selectively movable between a closed and opened position. A plurality of ultraviolet (UV) lamps may be positioned such that each storage compartment of the plurality of storage compartments receives UV light from a UV lamp of the plurality of UV lamps. At least one fan may draw air into the housing. A plurality of carriers configured to hold the plurality of laboratory consumables suspended from an upper surface of the carrier such that a distal end of each laboratory consumable hangs down into an open interior portion of the carrier. Each carrier having at least one side surface opening and at least one bottom surface opening to enable air flow and UV light to reach the distal end of each laboratory consumable.

A washing device comprises a manifold dispenser comprising at least one liquid input and a plurality of liquid outputs that operably direct fluid to contact a plurality of laboratory consumables held by a rack in the washing device. A number of the plurality of liquid outputs being at least equal to a number of the plurality of laboratory consumables such that each liquid output of the plurality of liquid outputs operably directs the liquid at a corresponding laboratory consumable of the plurality of laboratory consumables.

The invention concerns a household appliance, the household appliance comprising: a washing chamber for washing of items to be cleaned; a water system configured to feed water to and from the washing chamber for cleaning and/or rinsing of the items therein; wherein the water system comprises a UV-treatment chamber for disinfection and/or sterilization of water to be fed to the washing chamber during operation of the household appliance, wherein the UV-treatment chamber is provided with at least a first UV-light source arranged to direct UV-light towards water present in the UV-treatment chamber. The UV-treatment chamber is further provided with at least a first UV-light reflector. The invention also concerns a method for operating a household appliance.
