<p>A method of treating soiled textiles, wherein the soiled textiles are immersed in an aqueous liquor which contains at least two compounds inhibiting alkaline earth metal ion precipitation on said soiled textiles comprising using(1) from 0.2 to 10 gm of anhydrous active substance per liter of at least one finely-dispersed, water-insoluble silicate compound having a calcium-binding power of at least 50 mg CaO/gm of anhydrous active substance and having the formula, combined water not shown (M2/nO)x . Me2O3 . (SiO2)y where M is a cation of the valence n, exchangeable with calcium, x is a number of from 0.7 to 1.5, Me is aluminum or boron, and y is a number from 0.8 to 6, and (2) from 0.05 to 2gm/1 of at least one of certain complex polycarboxylates and/or polyphosphonates, as well as washing compositions containing said at least two compounds. - A</p> |
