YES ! Proper and routine maintenance for your hot tub chemicals can make the difference between your cover lasting 3-4 years instead of 5-7 years.
It’s very important to maintain your hot tub chemistry. Vapours from the water will be less harmful to your cover if they are balanced.
Remove the cover after treating your hot tub water to avoid corrosive vapours deteriorating the underside or liner of your cover.
A thermal blanket can reduce harmful chemical vapours from seeping into the cover and drastically cut down on evaporation.
