52 year old log cabin (half logs). Outside has been maintained periodically with creosote. 5 gal of creosote is still in garage. How do I prep surface before applying more creosote? or if not creosote, what should I use? North side is starting to fade and some areas leave dark residue on fingers when logs are rubbed. Browish liquid came off when I hosed it down to get rid of spider webs. Please advise.
