Abstract: A portable chemical dispenser for dispensing a chemical with a diluent includes a valve housing having a valve with an opened position and a closed position, an eductor housing coupled to the valve housing and including one or more eductors, and a nozzle coupled to the eductor housing and configured to direct the flow of a chemical solution to a receptacle, wherein the joint between the valve housing and the eductor housing permits relative rotations between the two housings. The portable chemical dispenser may also be devoid of metering elements that control the dosing of the chemical. A method of using the portable chemical dispenser is also disclosed.
