A contracter sanded down one room and the stairs in my home, then never showed up again. The wood on the stairs is very old (1936) and porous and some of the irregularities are very dark colored from stain in the woodgrain and I suspect water damage. What can I use to clean and finish these surfaces to at least make them acceptable looking? I've been living with this mess for almost a year and am anxious for a solution. I live in a very remote community and would rather take the job on myself than hire a local "professional".
Your help would be greatly appreciated.
