In time the sheathing breaks down, enabling water vapor to obtain entry to the core insulation, creating the lid to get in weight.
Cleansing the lid underside with a light quantity of hot tub surface area cleaner and a soft washing brush prior to washing completely with a hose, will reduce both the chemical attack as well as the mildew which grows and builds upon the wet vinyl which if you allow proceed will certainly start to rot the material, accelerating failing.
