    摘要: A method of conditioning the surface of a work piece, in particular of a litho-strip or litho-sheet, consisting of an aluminum alloy enables an increase in manufacturing speed in surface roughening while maintaining a high quality of the electro-chemical grained surface of the work piece with relative low effort related to facility equipment. The method of conditioning comprises at least the step of degreasing the surface of the work piece with a degreasing medium, wherein the degreasing medium contains at least 1.5 to 3% by weight of a composite of 5-40% sodium tripolyphosphate, 3-10% sodium gluconate, 3-8% of a composite of non-ionic and anionic surfactants and optionally 0.5 to 70% soda, wherein sodium hydroxide is added to the degreasing medium such that the concentration of sodium hydroxide in the aqueous degreasing medium is 0.01 to 5% by weight.
