A waste-oil cleaning method includes filling a processing tank (12) with waste oil, allowing non-oil liquids in the waste-oil to settle to the base (14) of the tank, then withdrawing the settled non-oil liquids from the base of the tank (74). After these non-oil liquids are withdrawn, the remaining partially cleaned oil is cleaned by pumping oil out of the tank and passing the oil sequentially through a mesh filter (26) and a centrifuge (22).
