Hi All! We are completing a renovation of our carriage house and have retained a lot of the old barn walls and beadboard. Once the contractors are out, I'm in to clean the walls! All I find on a search is about cleaning the wood after it's been removed to use at another location. (That entails hosing it down, etc. Not appropriate in this case.) Does anyone know of the correct product and method to do this for an indoor space? I was thinking of just good old Murphy's oil with a sponge or brush, but ... Attaching photos of what will be an exercise room. THANK YOU! (Sorry.... I don't know why one photo is so much bigger than the other. Hopefully, it'll correct itself when I post.)
