Care:  Boiled wool articles are easy to care for.  It should be cleaned very gently by hand.  The lanolin contained in wool protects the fabric from dirt and harsh environments.  If your boiled wool article does get dirty, you can shake or brush the dirt out very carefully.  If the boiled wool becomes stinky, just leave the article out overnight to air out, or in the bathroom while you shower (the humidity from the shower will help foul smells to disappear and will smooth out wrinkles).  If you do need to wash boiled wool, just wash by hand in tepid water using a mild wool wash.  Do not wring, squeeze, or rub wool.  Lay flat to dry.  You can read more here about wool care.  Don't forget your wool care products!
