    Abstract: A metal cleaning process in which the metal is contacted with an alkaline cleaning solution comprising at least 0.1 weight percent surfactant, at least 0.05 weight percent hydrogen peroxide, and an effective amount of at least one sequestrant, for example so as to stabilise the solution during use at 18 DEG C in an inert container prior to use so as that the peroxide concentration decreases by less than 2 percent in 7 days. A preferred sequestrant is sodium diethylene triamine pentamethylene phosphonate, used either per se or in combination with 2,2' dipyridylamine or 1,2'-diaminocyclohexal tetrakis methylene phosphonic acid. The metal may be contacted with the solution for between 1 and 120 minutes at a temperature in the range ambient to 70 DEG C. The metal may be rinsed with water after it has been contacted with the solution and air dried after it has been rinsed. The metal may be contacted with the solution in a metal or plastics cleaning bath which is preferably agitated or stirred, or a thickened solution may be sprayed onto the metal. The solution may be formed from a concentrate by dilution with water.

    Abstract: An aqueous bath for degreasing metals contains 0.5 to 8 g/l of polyoxyethylene alkyl ether with an HLB of 12 to 17 and at least one dissolved alkali metal salt or ammonium salt, contains 1 to 15 points of total alkalinity, and has a pH from 8 to 13. If the bath also contains dispersed conventional Jernstedt salt or insoluble di- or tri- valent metal phosphates with a particle size less than 5 mu m, the surface treated is conditioned for subsequent deposition of high quality zinc phosphate coatings at the same time its is degreased and can be effectively conversion coated by bringing it into contact with a suitable phosphating bath, without any rinsing with water between discontinuing contact with the degreasing bath and effecting contact with the phosphating bath. By this method, conventional degreasing, rinsing, conditioning, and zinc phosphating processes are shortened, cost less, and have less adverse environmental impact.
