Everyone who overwinters in the UK gets green fungus, and sometimes some black fungus, on their teak
decks by spring. It's a function of cold rain water
on the decks, and not being at sea enough. Once you start to get sea water
on them, followed by sunshine, it disappears. A good scrub accelerates the process.
Well, this year it didn't work for me. The problem I think was that I didn't go to sea AT ALL because my boat was being repaired for months after my collision
in October. The green has formed a kind of hard green-black coating which comes off with your fingernail, but otherwise is remarkably persistent. I have used Boracol (which previously worked miracles), we have scrubbed them twice (gently and across the grain with a soft sponge, of course), and since I'm in the brackish Baltic
, in lieu of seawater we have dumped buckets of fresh water with sea salt
dissolved in it. Nothing works.
I'm starting to think I need ScotchBrite pads -- carefully and across the grain. Will this destroy the teak
? Or what can I do? I've got to get this carp off somehow; it really looks awful.
