There is provided a cleaning liquid for semiconductor substrates having undergone CMP, the cleaning liquid being excellent in storage stability. In addition, there is provided a method of cleaning semiconductor substrates having undergone CMP. The cleaning liquid for semiconductor substrates having undergone CMP shows alkaline properties and contains: an amine compound that is at least one selected from the group consisting of a primary amine, a secondary amine, a tertiary amine, and their salts; a chelating agent; and water. The amine compound content is not less than 25.5 mass % and less than 90 mass % based on the total mass of the cleaning liquid, and the water content is 10 to 60 mass % based on the total mass of the cleaning liquid.

High active, high caustic liquid laundry detergent compositions which provide excellent stability are disclosed, including methods of making and using the same. The compositions generally comprise a source of alkalinity, a rheology modifier, one or more sequestering agents, one or more low mole ethoxylated nonionic surfactants, and an alkylpolysaccharide surfactant. The liquid detergent emulsions, provided as a concentrate, water-in-oil use solution emulsion, or oil-in-water use solution emulsion beneficially demonstrate improved stability even under high pH and high temperature conditions.

A method of cleaning soiled ware in a dishwasher the method having the step of using a water-soluble pouch, the pouch comprising a phosphate-free cleaning composition wherein the cleaning composition comprises loose powder and the composition comprises bleach, metal bleach catalyst and a complexing agent and wherein the complexing agent is slowly released as compared to the bleach catalyst.

The invention relates to a method of automatic dishwashing in a dishwasher having a wash tank, comprising: in a first step, delivering a first composition to dishware in the tank in the form of a mist; and afterwards, in a second step, delivering a second composition to the dishware in the tank in the form of a jet; wherein the first and second compositions are different, the first composition comprises a bleach, and the second composition is alkaline and comprises a builder. The invention also provides a dishwasher adapted to carry out the inventive method.

Stabilized compositions employing a sequestrant system and a binding system for improving shelf stability and dispensing stability of a solid activated bleach composition are disclosed. The compositions contain a peroxygen source and a catalyst activator which require generation of a peroxycarboxylic acid or other active oxygen sanitizing agent at a point of use. Stabilized compositions employ a sequestrant system including a phosphonic acid and/or dipicolinic acid sequestrant and a binding system comprising an anionic surfactant for a solid formulation of a catalyst activator and peroxygen source to provide shelf stability and dispensing stability for a activated bleach composition. Methods of formulating and use are further disclosed.
