1. A laundry method of simultaneously washing and whitening a polyester-containing textile garment, the method comprising:
- (a) treating under normal domestic wash conditions the textile garment with an aqueous solution comprising;
(i) from 1 ppb to 5 ppm of a hydrophobic dye, which is an azo dye, wherein the hydrophobic dye, when deposited onto the textile garment, provides a blue or violet shade to the garment that imparts a shading whiteness benefit thereto, and(ii) from 0.2 g/L to 3 g/L of a detersive surfactant, which is a mixture of at least one anionic surfactant and at least one nonionic surfactant, wherein the nonionic surfactant is present in an amount greater than 10 wt % of the total surfactant; and
(b) rinsing and drying the textile garment,wherein (a) provides a simultaneous washing and shading whiteness benefit to the polyester-containing textile garment.
