In the downstairs bathroom there is this tongue and groove wood on the wall, I don't know what kind it is, but it looks simular to hardwood flooring kind of wood. Except it's raw, not painted or anything. Is there a way to get all the water stains off? The water got on by brushing my teeth, shaking my hands dry, and other careless things I try not to do with water. It's looking really bad now, not serious, but you can notice them if you cock your head a certain way. If I sanded it I think it would be more noticable than if I left it be. I could always sand every square inch and paint with with a clear coat or something, but that takes time, which I don't have a lot of with school. Suggestions?
