What causes rain water to stain a rayon dress, so that even a dry cleaner can remove the “spots”?
Water can cause a rayon garment labeled “dry clean only” to fade tremendously. The “spots” you see where rain drops hit the dress are caused by fading, or running of the dye, and are not actually stains on the fabric. So, whenever wearing a “dry clean only” rayon garment in stormy weather, be sure to wear a raincoat and bring an umbrella. But, read the label, because some rayon is washable.
