Beach wear care. Three easy tricks to get more swim from your suit. Before you jump in the sea, or the pool, take a shower and saturate your suit in fresh water. Pool and seawater can deteriorate stretchy fabrics and fade colors. Keep your creams and suntan products on skin and off swimwear. After the beach, rinse out salt, sand and sweat in fresh water, roll in a clean dry towel. Handwash at home in mild detergent and warm water. Be gentle and rinse well before air drying in the shade. Keep your swimwear in a cool, dry and ventilated place, ready for the next wave.
