16. The composition of claim 1 , wherein the composition is free of any chemical oxidizing agent.

17. The composition of claim 1 , further comprising at least one chemical oxidizing agent.

18. The composition of claim 1 , further comprising:

d) at least one sequestrant;

e) at least one surfactant chosen from anionic surfactants, nonionic surfactants, or mixtures thereof; and

f) at least one thickening polymer.
