The Dark & Denim Laundry Detergent doesn’t treat dark color pigments like dirt or too aggressively. That’s what makes it so special; it preserves the colors and lets your darks and denims stay vibrant.
The clever thing about a modern laundry detergent like this is that, already at 20°C, it targets dirt and bacteria and dissolves and removes the remains with the washing machine water rinse. Washing at lower temperatures prolongs the lifespan of clothes and saves water and energy.
