We prepped this log church for restaining yesterday. My deceased father in law was a member there. All the sons and son in laws helped me. We did it in his honor.
It was a homebrew. Sodium Hydroxide, Potasium Hydroxide, Sodium Hypochlorite , TSP and soap. Neutralized with oxalic.
They are coming back over it with a semi solid. It would have been better if they hadn't let the front get in such bad shape to start with I guess.
Is there any way to get that deep black stain out of the logs?
