How do you repair stain on leather couch from hand sanitizer?

To repair a stain on a leather couch from hand sanitizer, first, gently blot the area with a clean, dry cloth to remove excess moisture. Then, use a leather cleaner specifically designed for your couch type to clean the area, following the product instructions. If the stain persists, apply a leather conditioner after cleaning to restore moisture and suppleness. Always test any product on a hidden area first to ensure it won't damage the leather.
