Bad move on the bleach. Old school! It will not be as much of an issue on the interior, but definitely do not use it on the outside. Borate should be applied to bare wood before staining and helps stop log rot and keeps wood boring/eating bugs from getting into the logs. Shell Guard from Perma Chink is the best in my opinion, but it needs at least two weeks of drying time before staining. Call Timeless Wood Care for more help at 800-564-2987.
