If its stain, that means it has penetrated the wood, albrit, not all
that deeply. To remove it, you have to remove the layer of colored
wood. Sanding would work; sandblasting could create a disaster...you
would probably need to use a material - maybe ground walnut shells? -
that is gentler than sand.

As well, simple pressure washing may work well enough. It depends on the
condition of the wood and the stain. I have had great success using a
pressure washer on stained wood, but it all depends...
