Abstract (en)
Ferrous metal parts are prepared for painting without a prewipe, but passed through two cleaning stages prior to phosphating. The parts are spray cleaned in the first stage by means of an aqueous liquid containing an alkali metal cleaner and a solvent-emulsifier, the concentration of the latter being several times that of the cleaner. In the second stage the parts are spray rinsed with a solution also containing an alkali cleaner and a lesser amount of a solvent-emulsifier.
