Wash the leggings in your sink with cool water and a small amount of mild detergent. Swish your leggings around in the soapy water for a few minutes, making sure to press the water into the leggings rather than wringing them. Afterwards, drain the sink and rinse your leggings in cool water until they run clear and there are no suds left. Hang them to dry and your all set. This is a safe way to get your leggings clean and feeling brand new!
