The ideal way to avoid damaging the wool is to store it in a closed cellar, protected from humidity.

If bales are left outdoors, consider:

• Do not store the wool in places that can be flooded or have excessive moisture on the ground.
  
• Store the bales in a vertical position, taking care that the lid is up.
  
• Do not leave the bales directly on the ground, it is necessary to do it on pallets or platforms, so that the air can circulate.
  
• Carefully seal the finished bales to prevent them from becoming damp during storage.
  
• If the bundles have to be outdoors for a long time, they should be covered with a tarpaulin to prevent them from getting wet in the rain. Prevent bales from being stored near gutters or downspouts of the sheds.

Avoid the presence of agents or products that contaminate the wool in the shed during shearing. This includes:

• Bags of seeds, food, fertilizers and other products that must be stored in polypropylene bags.
• Animal hair or other polluting fibers, from dogs, pets or leather.
• Paints, solvents or any similar product.

In order to avoid the presence of pigmented or medullated fibers, it is recommended to shear your animals in the following order:

• Animals of wool breeds (low risk of presenting medullated fibers or pigmentation).
• Animals of white breeds that have lived with sheep of breeds or crosses with greater pigmentation and medullated fibers. 
• Animals and crosses of meat breeds with a high level of medullated and pigmented fibers.
