Of course you want to keep your socks looking and performing as awesome as the day you bought them. We recommend cold machine wash with like colours, no bleach, tumble dry on low or even better hang up to dry inside. You want to protect the brilliant colours on your socks from the harsh sun, especially fluro colours so they stand out in the bunch forever. Do not iron (who irons socks anyway?) and no softeners as these break down the fibres of the knit. And here is a little tip if you get grease on your socks, wet the spot, rub lightly with a bar of sunlight soap or sard wonder soap rinse well in cold water and wash as recommended above.
