Letting the ink dry out completely makes the fabric ink last longer. Most of the fabric markers are washable, but still, some precautions need to be followed. To wash the fabric, turn it inside out and do not spray the fabric with any fabric protector as it will lead the ink to run out quickly. Always wash the fabric with cold water using any gentle detergent because harsh chemicals can cause the ink to fade out. Try to wash the fabric by hand instead of a machine and let it air dry to increase the durability and life of the painted fabric.
