Hand wash like a plate, in cold water using a mild washing up liquid like Ecover, Bio D or Method (better for the environment too).
Hot water and excessive scrubbing of the beeswax wrap will lessen the life of the wrap. I usually rub the washing up liquid on with my hands or if using a brush on certain areas only apply light pressure.
Leave to air dry, roll up and store ready for next use. Keep out of the dishwasher, microwave, washing machine, tumble drier or other hot surfaces!
Do not dry on heated surfaces!
