To launder, fill your sink or a plastic tub with cool tap water, adding one squirt of detergent to the water for each bathing suit you’ll be washing. Add your beach bathing attire. Let it soak for up to 30 minutes, swishing the water gently to help the cleaner reach deep into the fibers to pull out chlorine, oil, and dirt. Rinse well in cool water. Voila! Aside from that smile and the tan lines, it’s like beach day never happened.
