It is not uncommon for some debris to get stuck in the paddle. We recommend you soak the paddle in hot water over night and then try to separate the pieces. If this does not work, we would use some WD-40 along the connector pieces and see of that releases the paddle.
For future use, after paddling make sure to spray the paddles with fresh water to remove any debris or salt water before storage. Feel free to reach out to us at firstname.lastname@example.org if you have any questions!
