We purchased our log home less than a year ago. We have noticed that some of the rafters are black as well as some of the walls (knotty pine). Could this be mold? Is there a way to clean this such as bleach. Are most rafters stained to prevent this? If so, what type of stain is recommended? Thanks!

You could clean this with a mixture of one cup TSP & one cup bleach to 4-5 gallons of warm water. You should try rinsing with clean warm water also. It sounds like that you have an insulation problem and I do not think that staining or clear coating is going to help stop this problem.
