To maintain the cabinet finish, clean with soap and water. To maintain a “nearly original” appearance on your vinyl cover, apply a protectant with a high SPF at least once a month if exposed to direct sunlight. You will also want to clean and condition your spa’s cover monthly (or as needed based on the exposure of your cover). For more information on cover care, consult your dealer. The bottom line – don’t get obsessed about the numbers. The top manufacturers employ certified engineers to balance the plumbing system, place the jets in optimal locations, and decide which EXPERIENCE is best for you.
