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.
Treat stain within ONE hour after staining, otherwise the stain may be almost impossible to remove: Carefully remove the excess stain off the surface of the fabric with a paper towel. Rinse immediately with cold water to dilute the stain. Wash in maximum recommended temperature on the garment label with a double dosage of Universal Persil powder. If stain remains, try to remove stain with cholorine bleach, but then afterwards wash with Universal Persil powder once again.
