When constantly exposed to sunlight or mildew vinyl covers degrade quickly. Hot tub cover cleaners and protectors are the key to keeping your cover looking and performing like new.
The outer layer of nearly all hot tub covers is made from poly-vinyl chloride (PVC). In the manufacturing process the PVC is sealed with a special top coat containing compounds called plasticizers, plus softening agents to keep the material supple and attractive.
Vinyl is a UV-sensitive material which can degrade over time, particularly when exposed to sunlight or mildew. Sunlight breaks-down an unprotected vinyl surface, the plasticizers escape and the vinyl cracks, fades and fails.
Maintaining the integrity of the top coat and protecting against UV damage is the key to keeping your cover looking and performing like new.
