How do you get the smell of sulfur out of a swimsuit?

To remove the smell of sulfur from a swimsuit, first rinse it thoroughly in cold water to eliminate any chlorine or chemicals. Then, soak the swimsuit in a mixture of water and white vinegar (1 part vinegar to 3 parts water) for about 30 minutes, which helps neutralize odors. After soaking, wash it gently with mild detergent and rinse well. Finally, air dry the swimsuit in a well-ventilated area.
