Sunlight Pros and Cons
Hot sunny days are an ideal time to remove the foam inserts out of your hot tub cover to air them out and dry up any moisture in the foam.
However, prolonged exposure to sun can damage the acrylic surface of the hot tub (shell). Always keep your cover on the hot tub when not in use unless you are adding chemicals. In this instance leave the cover off for a minimum of 30 minutes.
