For synthetic fabrics, white vinegar is a fantastic option. Adding a cup of vinegar to the rinse cycle can help set the colors and prevent them from fading further. This natural solution not only enhances the vibrancy of the fabric but also helps eliminate any lingering odors.
For natural fabrics, such as cotton or linen, a mixture of salt and washing powder can do wonders. By combining two to three tablespoons of salt with your regular detergent, you can help revive the colors in your clothes during the wash. Salt acts as a natural color fixative, ensuring that the dyes remain vibrant and reducing the likelihood of fading.
