Ensure that the area where you store your rayon items is free of pests such as moths that could harm the material. Placing cedar blocks or lavender sachets with stored clothing can naturally repel insects without damaging the fabric.
Stains on rayon clothes are pretty conspicuous. Fortunately, they come off relatively easily. Remove stubborn stains on your rayon garments promptly using a gentle spot-cleaning solution of equal parts vinegar and water.
