I have real knotted pine 1962 - MURPHYS OIL SOAP - if some grease build up,
add a little dawn to it with HOT WATER. Don't drown the wall just a wet wipe.
It's finish is is LINSEED OIL which can be purchased at just about every
hardware store. Brush it in, let it dry. It takes time for the wood to suck up
the linseed oil. It will be tacky for a couple days to a week but will harden
to it's shine high gloss. Hope this helps you.
