Please follow the manufacturer's instructions on the laundry label. We recommend that you always turn garments inside out and close all zips. You should also avoid using fabric softener as it can cause skin irritation and prevent possible allergic reactions. For children's clothes, use a detergent that is labelled "sensitive". Another recommendation is to use a sensitive hygiene rinse, especially if the clothes can only be washed at 40° Celsius. Hygiene rinse agents remove 99% of the bacteria even at very low temperatures.
