- 4. A cleaning composition according to claim 1, wherein said isoascorbic acid is present in an amount between about 0.5 and about 10 weight percent of the composition.
- 5. A cleaning composition according to claim 1, wherein said isoascorbic acid is present in an amount between about 1 and about 5 weight percent of the composition.
- 6. A cleaning composition according to claim 1, wherein said surfactant system is selected from the group consisting of (a) a mixture sodium lauryl sulfate and sodium dioctyl sulfosuccinate, said sodium lauryl sulfate comprising between about 1 and about 20 weight percent of the composition, and said sodium dioctyl sulfosuccinate comprising between about 1 and about 30 weight percent of the composition; and (b) lauryl amido propyl betaine, in an amount between about 1 and about 40 weight percent of the composition.
- 7. A cleaning composition according to claim 1, further comprising an effervescing component, in an amount between about 1 and about 50 weight percent of the composition.
