Like all clothing, swimshorts don't like it if you treat them badly. They don't appreciate the contact with sun screen or with oil. We advice you to wash your swimshorts with clear water directly after you went for a swim in the sea or in the swimming pool. Afterwards, the best is to wash your swimshorts by hand and with cold water, in any case at a maximum of 30°C. Avoid dryers and dont iron the your new favorite. Take care - like this you will enjoy the swimshorts for a longer time.
