A detergent composition containing alkali-metal silicate with an average molar ratio of SiO,/M,O of 1-4.2, preferably 2.5-4.2, wherein M is an alkali metal, the composition being non-corrosive to glass, crystal, porcelain and decorative prints thereon upon repeated washing. The composition being such that when disposed in a washing medium at a normal working concentration, a protonated silicic monomer Si(OH),is produced in a concentration of at least 2.5&times;10,mol/liter of the washing medium.

Dishwasher detergent composition containing an anticorrosive agent

Provided are methods of washing fabric articles in the presence of silicone oils to provide for color protection and/or fragrance retention in the washing of fabric articles with detergents. Fabric articles are washed in a washing medium comprised of a major amount by weight of water, a first minor amount by weight of a detergent and a second minor amount by weight of an aminosilicone having the formula: ##STR1## wherein: the variables are defined in the specification wherein said first minor amount by weight is greater than said second minor amount by weight. In preferred embodiments of this method, said washing medium is the product of mixing water with a composition comprised of said aminosilicone compound in association with an insoluble support. In particularly preferred embodiments, an aminosilicone compound wherein R.sup.1 and R.sup.8 are both alkoxy, (typically methoxy) is employed. Provided are powder detergent compositions, without inorganic phosphates, for washing textiles, in particular colored textiles, comprising:
