Select Stain Type
Wool 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. Then saturate the stain with wool compatible stain remover and work it in, and let it set for 20 minutes. Rinse and launder with Perwoll Balsam Magic. If the stain remains, soak the garment in a sink with a solution of one part wool compatible stain remover to five parts water. Then re-apply wool compatible stain remover and launder as directed above. If dry clean only, take it to the dry cleaner for stain removal.
