摘要: An aqueous alkaline cleaning composition and process for aluminum container surfaces in a manner to inhibit objectionable white-etch staining during prolonged cycles brown oxide discoloration rinse which the solution contains an alkalinity agent or agents present amount sufficient remove fines from thereof, complexing complex at least some of metal ions tend form insoluble precipitates one surfactant organic soils being cleaned suppress formation cycles. The blend surfactants employed are further characterized by having Hydrophile-Lipophile Balance (HLB ratio) about 12. can optionally contain antifoaming foaming.
