HOW TO CARE FOR PRODUCTS CONTAINING WOOL
Wool is naturally odor-resistant and in many cases does not need to be washed nearly as often as you might think.
Here are a few tips on how to prolong the life of your wool garment:
You can use the garment several times before washing; just air it out and let it rest for a time between uses. It gives the wool fibers time to recover their natural strength and elasticity.
When it does need to be washed, then follow washing instructions in the garment label, using cold water and a mild liquid detergent (even better if you have one designed specifically for wool) and dry it out flat.
