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, rinse back side of the stain under cool, running water. Apply an oxygen-based stain remover onto the stain, work it in and let it set for 20 minutes. Rinse and wash with corresponding Persil powder. If the stain remains, soak the garment in a sink with a solution of one part oxygen-based stain remover to five parts water. Then re-apply oxygen-based stain remover and launder as directed above. If dry clean only, take it to the dry cleaner for stain removal.
