Bob,
As the other poster indicated, if you can find out what caused the
stain, the better off you will be in selecting a "bleaching" mechanism. What
I have found to be dam near impossible to fix is urine stains from a cat.
Not sure why, but this seems to be the toughest staining problem to fix. I
gave up and replaced those boards in my house. Previous owner I guess was
not too clever at taking care of thier animals. When you do select something
keep in mind most of these stains are not a fixed darkness. You will have to
be careful not to "overbleach" a area. That will stick out just as bad. I
would use any solution in a diluted state and try repeated treatments rather
that one heavy treatment. This way you can adjust the approach based on the
results.

What type of wood and what caused the stains?
Possibilities are:
