Winter’s ice and snow is hard on your spa cover. The weight of ice and snow will cause the cover to sag and water to collect and puddle on the cover, causing it to fail sooner. Flipping your cover inserts can help prolong the life of your cover. Unzip the cover and pull your inserts out. Flip them over and reinsert them so that now, the crown is up. Clean your cover with a little baking soda and water.
