Composite deck and acids

[mike movila 78]

I have been requested to clean a composite deck that has composite floor and the railing is made of wood I cleaned the wood part and now I want neutralize the deck with acid. Correct if I am wrong my understanding is that acid is not meant to touch the composite, therefore composite should be protected

Prewet the composite first since you have to neutralize the wood rails.
