   Sodium hypochlorite is chlorine bleach, reasonably safe on most metals.  Probably the biggest concern would be that it might cause paint to fade on painted metal, though it could in theory cause rust to appear on bare steel surfaces.

   "Wood bleach", on the other hand, often contains oxalic acid, a chemical which miraculously removes rust from steel, but also removes the protective anodizing coating from aluminum.  One needs to take considerable care to keep it away from aluminum.  And some wood cleaning products may contain potassium hydroxide, a highly corrosive product that will attack most metals.

   Of course, it's always wise to test a bit of the product on the proverbial "inconspicuous area" before committing to its use.

   Question for the deck cleaner manufacturer.

   " the deck cleaner warns against coming into contact with metal"

   How do you avoid the nails, screws or the other fasteners holding the decking?

   Being around the causic enviroment of a pool is far more damaging then spraying and rinising witha little bleach.

   Makes sense.
