Dish soap (ideally dye-free) diluted with water: Dish soap will gently remove stains without damaging rug fibers. When it comes to wool, avoid using too much soap. Stain remover (like Zout or Resolve): For those stubborn stains, a stain remover will come in handy. Water: For soap diluting, washing, and rinsing, use water. If the stains persist, we recommend that you hire a professional to remove them.
