ABSTRACT:
An apparatus useful for providing a plurality of chemical compositions useful to clean an item, e. g., a tank comprises a plurality of reservoirs each containing a concentrated form of a different chemical composition and each having an outlet through which the concentrate exits the reservoir; a subsystem for providing diluent to the concentrates which exit the reservoir to form the chemical compositions; and a control subsystem to automatically control the time during which each concentrate exits from each reservoir. A method for providing chemical compositions useful to clean an item is also disclosed.
