How to clean your Neoprene boots?
· Unless you dive exclusively in freshwater, it's important to rinse all neoprene items after every dive.
Salt water causes neoprene to degrade and lose its flexibility.
All divers should clean their boots with a prolonged soak in warm water.
Here are the basic steps:
1- Undo Velcro and open all zippers , submerge and gently massage items then rinse thoroughly
2- Dry the boots and zippers open, store in a well-ventilated area away from direct sunlight.
