摘要: The invention includes a method for cleaning and passivating stainless steel surface comprising: 1) contacting the with 15-48 ml/liter of an acid formulation comprising between about 1 60 % component, 1-15 surfactant, 39 98 water; 2) maintaining contact to dislodge remove residue from surface; 3) continuing complex free iron ions liberated form oxide film on 4) precipitate complexed into film.
