Our advice for keeping your board as long as possible
After every session, use the beach shower to rinse your board before the sand dries on the wax. If you don't have fresh water nearby, dip your board in the sea one last time on both sides.
Be sure to also rinse the rip-tab parts of your leash thoroughly to remove any remaining grains of sand which could make them more difficult to fasten during your next session.
We recommend that you then dry your board with a towel or your poncho and store and transport it in an anti-UV cover to prevent the foam of the board from yellowing or, worse still, deforming. The high temperatures in cars can damage your foam board.
Always try to store your board in your garage between sessions rather than in your car.
