Cleaning your scuba fins is one part of the equation and the next would be storing it away. Whether you are planning on storing it away for the winter or just for a couple of weeks, you can still do so in the following manner. For starters, you want to ensure that your fins are dry as storing them in moisture is not ideal. To do so, simply allow it to air dry; making sure to avoid direct sunlight. Now that your fins are dry, all you need to do is find a dry and relatively cool location.
No matter where you decide to store your fins, though, they need to be completely flat. Even the smallest angle can cause the fins to warp and permanently have a bend. Also, avoid hanging them up by their straps as this can wear down the straps faster.
