The present invention relates to a degreasing and anti-corrosive agent for metals, metal components and metal objects, which agent consists of defined quantities by weight of phosphoric acid, zinc phosphate, at least one polymer or polymer mixture and/or corresponding quantities by weight of a reaction product with one or more of the constituents, preferably a reaction product with phosphoric acid or phosphate ions, water, preferably deionised water, and of at least one aliphatic alcohol and of at least one further non-polar solvent (chlorinated hydrocarbons) and an aromatic solvent and/or at least one polar and/or aliphatic solvent. The invention also relates to a process for producing the degreasing and anti-corrosive agent and to a process for degreasing and simultaneous anti-corrosive treatment of metals, metal components and metal objects with the use of the agent.
