I'm no sure how long the boat was in this condition but once it was drained there was a 12 inch band of black residue around the perimeter of the interior. The wood is teak and is in excellent shape except for this mess. I took a door off and tried cleaning it with mineral spirits. The oil came off but not the black stain. Any ideas how I can restore the wood back to its orange color. Thanks

Here is what you need to do:
1. Using a small screwdriver, anvil - heck even a nail... poke into the "blackened" areas. If the object injects itself easily - the black is ROT and not just mildew.
2. If the case is above - you are gonna have to consider one of two things. Digging it all out - and filling with epoxy, taking the effected pieces out - cutting off the rotted areas and tab in replacement.
3. If its just soft kinda soft - meaning it pierces but doesn't go anywhere - (like a scratch)... first try a 10:1 water / bleach solution. Use a brush and liberally coat the area. Let sit for 24 hrs - and if it is just mold it will go away with a greenie or fine grit 3M sand pad - and you'll have to do this and try to go with the grain - I prefer doing a wet sand as it helps bring out the bleach.
The reason I state this - is that there is a big difference between rot and mold although esthetically they will have they same appearance initially until some physical test is conducted outside of sanding a horizontal surface.
Acid solutions are not good because most do not due the diligence of rinsing the wood of the acid and in the case of teak - acid strips the wood of it oils causing the grains to lift and inducing a weakness in the wood as those fibers are now expanded to a lesser density. Bleach is mild - but is extremely effective.
