Wash mixed colours with confidence. Dr. Beckmann Colour & Dirt Collector Sheets keep your colours brighter for longer. One sheet per wash will collect the dirt and dye that can come out of your clothes, transferring to others and causing colour loss and dullness of fabrics. The proven microfibre structure locks colour securely in. At the same time colour collecting molecules, released from the sheet, bind efficiently more colour in the water. As a result, your laundry stays fresh and vibrant looking. Makes your life easier Ideal for all multi-coloured clothes with patterns, stripes or even a mixed load containing different colours. Works at all temperatures.
