- 11. A stonewashing composition comprising a lipolytic enzyme and a cellulase.
- 12. The composition of claim 11, further comprising a surfactant.
- 13. The composition of claim 11, wherein the lipolytic enzyme is a biopolyester hydrolytic enzyme.
- 14. The composition of claim 13, wherein the lipolytic enzyme is a cutinase (EC 3.1.1.74).
