I am in the process of building a log home. We had to cut the all thread, that run through the logs, shorter for the center beam to be hung. We ended up cutting the all thread with a grinder and then it rained so the ash ran down the logs. The log walls are now a black dingy color. We tried to spray off the logs with water but that only made it worse. How can I get the black residue off the logs?
