[origin: EP0282863A2] 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.
