How do I clean my hot tub cover?

A hot tub cover is an essential part of hot tub maintenance. A proper and diligent hot tub cover care routine can be the difference between needing to buy a replacement cover in 7 years instead of 5 years. Here are some tips to increase the lifespan of your spa cover.

  • Keep the cover clean.The vinyl needs to stay clean and conditioned. Use a very mild detergent and water solution to clean the vinyl portion of the cover at least twice per month to keep your spa looking great and help expand the life of your spa cover.
  • Wipe chemical residue from the underside of the cover every chance you get. These residues, if left on the cover, start to break down the material causing it to become porous.
  • Maintain proper spa water chemistry.The better your spa water chemistry is maintained, the less corrosive vapors will be coming off the tub. Corrosive vapors cause the protective layers of the cover to degrade. More vapors results in more damage, and a shorter cover lifespan.
  • Unzip the cover and clean just inside the zipper at least twice per year. Mildew has a tendancy to build up indide the xipper, and if you have not kept your sanitizer levels up, this may develop into problem.
  • Remove the cover for 20-30 minutes after shocking your spa water. As the shock is burning out the Chloromines and Bromimines in your spa, highly corrosive vapors are released. Again, these vapors could lead to a shorter cover lifespan.
  • Completely remove the cover at least once per week to allow the water to drain out of it. Always completely remove the cover while using your hot tub.

Cover life expectancy depends on a lot of factors including the amount of direct sun the cover receives, how much rain or snow is allowed to gather on top, if it is cared for correctly or abused, how the spa chemical regimen is followed, and varying weather patterns.
