A faucet cleaning assembly includes a pouch which has an inner layer and an outer layer. The inner layer is comprised of a fluid impermeable material defining an interior of the pouch thereby facilitating the interior of the pouch to contain an acidic solution. The pouch is positionable around a faucet thereby facilitating the acidic solution to dissolve mineral deposits on the faucet. A band is integrated into the pouch and a drawstring is integrated into the band. The band is collapsible when the drawstring is tightened for retaining the pouch on the faucet. A lock is slidably disposed on the drawstring to retain the drawstring in a tightened condition for retaining the band around the faucet.

In one example, a fluid flow restrictor has a housing outlet offset from a housing inlet along a fluid flow direction so as to define a channel therebetween. A rotatable body that is disposed in the channel defines a bore that extends entirely therethrough such that the bore defines a bore inlet and a bore outlet. The flow restrictor has an interior surface disposed in the bore that defines an orifice having a cross-sectional dimension that is less than a cross-sectional dimension of the channel such that the orifice can restrict a flow of fluid as the fluid flows between the housing inlet and outlet. The rotatable body is rotatable between 1) a first orientation, where the bore outlet is offset from the bore inlet along the fluid flow direction, and 2) a second orientation, where the bore inlet is offset from the bore outlet along the fluid flow direction.

A liquid dispenser. The dispenser includes reversible modular components to define selective removability and rearrangement between them and a base structure such that one or more sheets of a passing liquid-receiving substrate may receive such liquid through interchangeable liquid-dispensing orientations. The removability features include tool-free operation to facilitate quick insertion and removal of the modular components that include at least a liquid-dispensing valve assembly and a seal that is selectively engageable with the valve assembly to protect liquid-dispensing nozzles of the valve assembly from becoming clogged with residual dried liquid during periods of inactivity of the liquid dispenser. Selective movable cooperation or attachment between the modules—as well as between the modules and the base structure—facilitates flexible configurations of the dispenser, including top-down and bottom-up liquid-dispensing orientations.

A fluid cartridge for a plural component sprayer is configured to receive first and second component materials and purge air from the sprayer and provide the first and second component materials and purge air to a mix chamber for spraying. The fluid cartridge includes a cartridge body, material flowpaths extending from a second end to a cartridge bore, and a purge path extending from the second end to the cartridge bore. Fluid checks are disposed in the material flowpaths and purge path to prevent backflow out of the fluid cartridge. Side seals are disposed in the material paths and are pre-loaded to extend into the cartridge bore and engage a mix chamber within the cartridge bore.

Buildup in a plumbing fixture is removed by providing a bag containing a quantity of concentrated fixture cleaning chemicals and then securing the bag to the fixture to be cleaned. After securing the bag to the fixture, the bag is filled with water from the fixture which mixes with the concentrated chemicals to create a cleaning solution that covers the fixture, and then the fixture is allowed to soak in the created cleaning solution to thereby dissolve the buildup.

An application device according to an embodiment includes a liquid nozzle part, an air nozzle part, and an ejection controlling unit. The liquid nozzle part ejects liquid to be applied to an electronic component mounted on a substrate. The air nozzle part ejects air toward the substrate. The air nozzle is concentrically arranged with respect to the liquid nozzle part. The ejection controlling unit ejects the air from the air nozzle part at a timing in synchronization with an ejection timing of the liquid to be applied by the liquid nozzle part.
