Small quantities of dirty oil used in industrial facilities, such as hydraulic fluid, lubricating oil and the like, are reclaimed by placing a batch of such fluid in a relatively small, vertically axised tank having an elongated, transversely arranged, low-temperature heater located a distance above the tank bottom. The heater causes the fluid to generally circulate upwardly and downwardly in closed loops within the tank portion above the heater so that foreign particles and water gravity-settle into the tank portion below the heater. Transversely arranged rows of permanent magnets located in the tank above the heater attract and immobilize magnetizable ferrous particles carried by the fluid. After a period of fluid circulation, the cleaned fluid located generally above the heater is pumped out of the tank for re-use. The fluid and the settled foreign materials, including the water, sludge, dirt and the like accumulated in the bottom of the tank, beneath the heater, are periodically drained from the bottom of the tank.
