osoteI’ve a 35 year old cabin that has several ‘railroad tie’ style retaining walls. While the cabin itself has been oiled/stained every 3-4 years and looks great, I doubt anything has been put on these logs since they were set in place. They are still doing the job but are greying out, getting deep grooves in the grain pattern. I’ve no idea if they were originally treated with creosote or what type of dark oil was used for original water sealing. Is there something I could spray/apply to
