Not all socks are made of washable materials, and you may need to know what cleaning products to use and how much soap. But don't overthink it! A good rule of thumb is a cold hand wash with extra care with wings and other accessories. Also, make sure you read the label before tossing your adult novelty socks in the washer for the first time - we recommend hand-washing Madmia socks to prevent any possible damage. Madmia is not liable for any damages caused by not following these instructions.
