Fill a container with cool water and add mild liquid laundry detergent. Avoid using bleach if your macrame is colored. Agitate and swish the macrame in the water to rinse out any detergent. Drain the water from the container and refill it with clean water. Agitate and swish the macrame in the water again, repeating this step several times to ensure thorough rinsing. Drain the water from the container and gently squeeze out any excess water from the macrame by pressing it with your hands. Hang the macrame in a well-ventilated area to air dry. Choose a location where air can freely circulate around the macrame. Allow sufficient time for the macrame to dry completely.
