Simple detergent or dishwashing soap can be more than sufficient already. Simply add this solution to a tub or small bath with water, and then let your snorkel soak. Simply soak it in the solution, clean the outside with a sponge, scrub the snorkel inside with this brush and wash off any dirt that may have gotten stuck inside. If you clean your freediving snorkel regularly, it will keep the snorkel looking as new.
