Staining teak is generally a bad idea. I've seen it tried twice (Albin
trawler and Jeaneau 41). and in both cases it was a disaster.
The problem is that teak is oily and hard to stain evenly. If your teak
has been ignored over the years and drier (In that you didn't oil it),
it might stain more evenly. Depending on the condition of the wood and
it's depth, it may be hard or even impossible to undo the staining
process.
After he tried it, the owner of the Albin told me it had been as dumb
as painting a DeLorean. Teak is a gorgeous wood. Don't stain it.

Good luck in any case!
