Cleaning a stinky neoprene bag can be done effectively with a few simple steps:

Rinse with Water: Start by rinsing the neoprene bag thoroughly with fresh water. This helps remove any surface dirt, debris, or salt residue.

Prepare Cleaning Solution: Create a cleaning solution by mixing mild detergent or dish soap with water. Ensure that the detergent is gentle and doesn't contain harsh chemicals that could damage the neoprene material.

Spot Clean: Use a soft brush or cloth dampened with the cleaning solution to spot clean any stubborn stains or areas of the bag that are particularly smelly. Gently scrub the affected areas in a circular motion.

Rinse Thoroughly: After spot cleaning, rinse the entire bag again with fresh water to remove any soap residue and ensure thorough cleaning.

Air Dry: Hang the neoprene bag in a well-ventilated area to air dry completely. Avoid direct sunlight, as prolonged exposure to sunlight can degrade the neoprene material over time.

Deodorize: If the smell persists after cleaning, you can try deodorizing the bag by placing it in a well-ventilated area with good air circulation. You can also use products like activated charcoal sachets or baking soda placed inside the bag to absorb odors.

Store Properly: To prevent future odor buildup, make sure to store the neoprene bag in a clean, dry place when not in use. Avoid storing it in damp or humid environments, as these conditions can promote mold and mildew growth, leading to unpleasant odors.

By following these steps, you should be able to effectively clean and freshen up your stinky neoprene bag, restoring it to its original condition.
