Select Stain Type
Rayon generally should be dry cleaned. Always follow garment label instructions when pretreating and laundering your clothes. For colored garments, test an inside seam for colorfastness.
Quick solution: Soak stained garment in cold water for 10 minutes or rub the stain away with a tab of aspirin and water. If the garment is washable, for fresh stains, apply corresponding Persil powder diluted in lukewarm water or alternatively a stain remover onto the stain, cover the stain and let it set for 20 minutes. Then wash with corresponding Persil powder and a color-safe bleach for colored fabrics. For white fabrics use a chlorine bleach, but then afterwards wash garment with Universal Persil powder once again. If dry clean only, take it to the dry cleaner for stain removal.
