Abstract (en)
Liquid alkaline cleaner concentrates which have the following components: a) 80 to 99.7% by weight of an aqueous solution of a builder or builder mixture, containing 50 to 60% by weight of water and at least one alkali metal silicate and/or alkali metal phosphate, b) 0.3 to 22% by weight of a surfactant combination consisting of anionic surfactants, non-ionic surfactants and alkyl glucosides. Cleaner concentrates of this type are used in the cleaning of metal surfaces, in particular of steel, nonferrous metals, copper and zinc before refining processes and intermediate cleaning before working processes.
