How do I remove a grease stain from a wool dress?
assistant
The best way to remove a grease stain from a wool dress is to first pretreat it with a solvent-based prewash product and then prewash the fabric with a mild detergent. If the stain is still present, spot-treat it with a cleaner specifically designed for wool, then launder with a gentle, wool-safe detergent.
