Basic Wool No No's
First, it is important to check with the manufacturer on approved washing methods and products. Washing wool in a machine or using products with synthetic fragrances may render the return/refund policy null and void. Although all of these methods and products are generally accepted, often used, and considered safe, its always best to check the manufacturers policies.
Never ever....
- shock wool with abrupt temperature changes.
- twist or wring wool.
- run wool through the dryer.
