I have a friend who owns this wooden trunk/chest. I do not recognize the wood. The chest was purchased in the late 50s in the Marshall Islands or possibly Japan. A couple years ago my friend put a tray of plants on the chest and the tray wasn’t waterproof as they had been led to believe. In addition to the water damage, it also appears to be growing mold. I have not tested the finish but I suspect it is some sort of laquer. They would like the chest refinished and the mold removed. My expertise is really in art more than woodworking.
Can someone offer some advice on this?

My best guess from what I can see, is that it is made of teak.
I agree with Bruce that it appears to be teak. Lacquer,or possibly shellac are the likely finish would think. But, if the trunk is now in a dry environment it isn't likely to be mold currently growing. It may well be that the dark area is a mineral stain caused by iron or other minerals in the water.
The repair calls for chemically stripping the old finish. Those containing Methylene Chloride are most effective though the fumes are hazardous and it should be used only with AMPLE ventilation. You will need some stiff brushes to remove stripped finish from the carvings.
Then you can address the darkened area. I suspect that your best bet is Oxalic Acid--it is found in most paint and hardware stores, sometimes labeled wood bleach. (Don't confuse it with the two-part product also labeled wood bleach--that's likely to be major overkill.) Oxalic acid usually does a pretty good job on such stains, and doesn't dramatically alter wood color. You may want to apply it tom the full surface of the panel to help ensure a more even overall result.
Thanks guys .. good advice. I'll test the finish to be sure. I'll give the oxalic acid a try. Thanks again!
