Hi, I have a 5 yr old log home I recently purchased. The logs have never been stained or sealed. On the interior there is a grayish, colour randomly throughtout the logs. It looks like smoke, it’s it’s not, just the best description I can give. What can u suggest I do/use to remove this prior to staining, I live in Ontario Canada. Thanks
