Your Beachcomber Heatshield Cover should last from 3 to 5 years, depending on the weather, snow load, local conditions, usage and many other factors. Ensure that there are no extra loads on your hot tub Heatshield, like a sleeping dog, or other weight. Do not allow children to climb on, sit or stand on your hot tub Heatshield. Observing common sense and caring for your hot tub cover will help it last and perform for you for many years. Beachcomber’s water care product called ‘CoverAll’ is a specially formulated protectant and cleaner that you can use on your Heatshield to keep it clean, free of mold or mildew, and looking new for years to come.
