A cleaning system for cleaning a plurality of service tanks located at different sites spaced widely apart from each other. A set of storage tanks is located at one site, for storing cleaning solutions, each cleaning solution being recirculated through a respective recirculating line from each storage tank. The cleaning system further includes cleaning stations, one for each service tank assembly, each located close to its respective service tank assembly, each cleaning station having a connection to each recirculating line. Each cleaning station includes a wash/motive tank for a washing liquid, a rinse tank for a rinsing liquid, and an outlet line leading from each of the wash/motive tank and the rinse tank. Liquid is conveyed from the outlet lines of the wash/motive tank and rinse tank to the respective service tank assembly via a feed line. A return line is adapted to return liquid from the respective service tank assembly. An eductor has a vacuum opening connected to the return line. A motive pump delivers liquid from the outlet line of the wash/motive tank through the eductor to create a vacuum in the return line and draw liquid from the service tank assembly. Also included is a method of cleaning the service tank assemblies by use of the cleaning stations.
