Treatment of Teak Decks

In bygone years it was generally sufficient to scrub down a teak deck with green soap every now and again. This would lend the wood a beautiful white-grey tone which would protect the surface from the elements like a patina. Sadly this is no longer sufficient.
The wood needs protection from aggressive industrial emissions, otherwise dirt will penetrate too deeply to be removed, damaging the wood, particularly between the grain.
