Re: Teak Fungus
Fungi spread by showering their spores all over the area. The spores are extremely resistant to chemicals. You'll need a fungicide. If having teak fungus is a common problem where you keep your boat, possibly one of the local shipwrights will know what is working best at your location.
Fungus infections can be very hard to get rid of, and sometimes, one can't.
Household bleach does kill lots of organisms, and sorry, I don't know what kills fungus, only have failed to eliminate it under a toenail. Full strength bleach could bleach your teak, and I don't know if it will kill the fungus spores. If in fact it is fungus....do you know that for a fact? or is it hearsay?
