Persil Liquid Detergent for White Thobes and Clothes cleans effectively and gives white thobes the brightest whiteness wash after wash compared to any powder detergent, even if mixed with bleach, due to Persil’s German Opti-Bright Technology. The innovative Oud fragrance variant of the detergent was developed by Global Perfume Experts, based on an insight that GCC nationals apply Oud when wearing thobes.
