I have posted several times that IMO selecting a dealer is an integral part of the spa experience, so I don't want to sound like I am questioning his advice but was curious about something I was told yesterday. (our tub sits covered and empty until Tuesday when the electrician can get here). The Optima's manual states something about using a cleaner and polish prior to use. Since I have a few days, I called to ask him about it and he said not to use spa cleaners because some of them will leave a residue that will only come off in the water and filter. Likewise for any wax products. He stated just a wipe down with a damp towel should be enough, and that he uses Formula 409 to clean his. He said don't spend money where you don't need to. He also said to only use saddle soap on the cover, and definately not Armorall etc. Any comments?
