I actually found the following info online from a hot tub dealer. Any thoughts on which one would work best? Also what sort of brush / sponge do you think would work well on the shell without scratching it? I need something to help me scrub it.
Thanks.
When the hot tub is empty, you
can clean the surface by using a mild, nonabrasive liquid detergent, or specially formulated hot tub cleaner. For general
cleaning, any of the following items can be used: Ivory (soap & water solution), Formula 409, Windex, Spic and Span,
Scrubbing Bubbles, Fantastik, Simple Green, Pine Sol or any product available at your local hot tub dealer. For heavy
cleaning, you may try one of the following cleaning items: Soft Scrub (may slightly abrade surface), Bug & Tar Remover
or OOPS. Do not use an abrasive brush or cleaning agent, as it will scratch the finish. DO NOT USE any of the following items to clean your tub: Acetone, Goof Off or any cleaners that contain esters, ethers, ketones, aromatic or chlorinated hydrocarbons, Isopropanal (concentrations greater than 25%).
