I have had a similar problem on internal teak coamings and this worked really well



But I will add a couple additional steps..

Mix the Oxcalic Acid ( powder) with hot water, stir for a long time and make sure it completely dissolves. I use a small utility spray bottle on stains to "feather" it into the surrounding surface. The same thing will work to remove stains of tannic acid stains from numerous woods.
