Cleaning and polishing the acrylic surface
Each time you drain your spa, before you refill it
you should clean your spa shell with an all-purpose cleaner and apply a
coat of surface protectant.
Use a low detergent, non-abrasive cleaner
specifically formulated to clean the spa without damaging its acrylic
Use a non-oil based surface protectant that is
specifically formulated to protect the spa’s finish from the chemicals
and minerals associated with normal spa use.
