Handwash your swimwear in cold water with a gentle detergent or soap. Avoid using typical laundry detergent or harsh chemicals as their pH levels are unsuitable for swimwear and can weaken the fabric and cause colours to fade. Gently rubbing the fabric together helps to remove any dirt or oils without causing abrasion. We strongly advise that you do not use a washing machine. The harsh tumbling and hot temperatures of machine washing can easily loosen and breakdown the swimwear's fibers, which then leads to fabric pilling, colour fading, and the fabric and rubber may stretch. A usual 40 degree wash will damage your swimwear due to the hot temperature of the water.
