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.
If the garment is washable, apply corresponding Persil gel or corresponding Persil powder diluted in lukewarm water onto the stain, cover the stain and let it set for 20 minutes. Then wash with double dosage of 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.
