Abstract
This invention relates to cleaning compositions with controlled dissolution and improved chelation system. The cleaning composition is generally comprised of a majority by weight of a percarbonate compound, a chelation system, and a binder system. The invention also relates to non-oxidizing solid cleaning compositions containing peroxide moieties. These compositions are ideal for use in cleaning appliances, such as automatic washing machines and dishwashers.
Claims33
A method for cleaning an automatic washing machine comprising the sequential steps of:
- (a) providing an automatic washing machine having a wash tub;
- (b) adding a sufficient amount of a cleaning composition to the wash tub, wherein the cleaning composition comprises:
- i. a majority by weight of a percarbonate-based compound;
- ii. a chelation system, wherein the chelation system is comprised of at least one carboxylic acid compound;
- and
- iii. a binding system, wherein the binding system is comprised of at least one polyol and a second binder component;
- (c) adding a sufficient amount of water to the wash tub to allow the cleaning composition to dissolve and form a mixture of water and cleaning composition;
- (d) agitating the mixture of step “c”;
- (e) removing the mixture of step “c” from the wash tub;
- and
- (f) rinsing the wash tub.
